Explanation

Dry ice is the common name for solid carbon dioxide (CO2). It is referred to as "dry" because, at standard atmospheric pressure, it sublimes directly from a solid state to a gaseous state without passing through a liquid phase. This property makes it useful as a cooling agent, as it does not leave any wet residue upon warming.

Explanation

Long-sightedness, medically known as hypermetropia or hyperopia, occurs when the eye focuses light behind the retina, causing close objects to appear blurry. To correct this vision defect, a converging lens is required. A convex lens is a converging lens that helps to converge the incoming light rays before they enter the eye, ensuring they focus precisely on the retina, thereby restoring clear vision for near objects.

Explanation

A rainbow is an optical and meteorological phenomenon caused by reflection, refraction, and dispersion of light in water droplets, resulting in a spectrum of light appearing in the sky. For a rainbow to be visible, the sun must be behind the observer and the rain in front. At 12 o'clock noon, the sun is directly overhead or very high in the sky. In this position, the angle required for the sunlight to reflect within raindrops and return to an observer's eye is such that the center of the rainbow would be below the horizon, making it impossible to see a rainbow.

Explanation

For shaving purposes, a mirror that provides a magnified image of the face is generally preferred to allow for greater precision and to see fine details. A concave mirror has the property of producing a magnified and upright (erect) image when the object (the face) is placed between its pole and focal point. This magnification helps users to shave more effectively compared to a plane mirror, which produces an image of the same size, or a convex mirror, which always produces a diminished image.

Explanation

Blood group O negative is widely recognized as the universal donor blood type. This is because red blood cells of O negative individuals lack A, B, and Rh antigens, which are the primary antigens that can cause severe immune reactions during a transfusion. This makes it compatible with most other blood types, especially in emergency situations.

Explanation

Photosynthesis is a complex biochemical process by which green plants, algae, and some bacteria convert light energy into chemical energy. This process is highly dependent on the availability of sunlight, as it drives the light-dependent reactions. While some parts of the photosynthetic process, like the Calvin cycle, can occur in the absence of light, the initial energy capture and conversion critically require light, making it primarily a daytime phenomenon for most photosynthetic organisms.

Explanation

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll. The overall chemical equation for photosynthesis shows that carbon dioxide (CO2) and water are reactants, converted into glucose (sugar) and oxygen. Carbon dioxide serves as the essential source of carbon atoms for building the carbohydrate molecules produced during the process.

Explanation

Jean-Baptiste Lamarck was a French naturalist who proposed one of the earliest theories of evolution in the early 19th century, before Charles Darwin. His theory, often referred to as Lamarckism, suggested that organisms acquire characteristics during their lifetime in response to their environment and can then pass these acquired traits on to their offspring. Although largely disproven, he was a pivotal figure in initiating discussions on the transformation of species over time.

Explanation

Har Gobind Khorana, an Indian-American biochemist, was awarded the Nobel Prize in Physiology or Medicine in 1968 for his work on the interpretation of the genetic code and its function in protein synthesis. A significant part of his pioneering research involved the chemical synthesis of nucleic acids, specifically the first artificial gene, which demonstrated the principles of DNA synthesis in a laboratory setting.

Explanation

Water exhibits an unusual property regarding its density compared to most other substances. As water is cooled, its density increases, but only up to a certain point. Its maximum density occurs at approximately 4 degrees Celsius. Below 4 degrees Celsius, water begins to expand, and its density decreases until it freezes at 0 degrees Celsius, which is why ice floats on water.

Explanation

Mango showers refer to the pre-monsoon showers that occur during March-April in parts of India, particularly in southern states like Karnataka and Kerala, and also in eastern states like Bihar and West Bengal. These localized rainfalls are crucial for the ripening of mangoes, coffee, and other seasonal crops, hence their name.

Explanation

The Nilgiri Hills are a prominent mountain range located in the southern part of India, specifically at the trijunction of Tamil Nadu, Kerala, and Karnataka. This region is widely recognized as the geographical point where the Eastern Ghats and the Western Ghats converge. The Eastern Ghats gradually merge into the Western Ghats in the Nilgiri massif, forming a significant biodiversity hotspot and a complex mountain system.

West Bengal held the first position, followed by Kerala in the second position. Bihar's population density was 497 persons per square kilometer, placing it after West Bengal (767) and Kerala (749).

Explanation

In 1999, and for a significant period before and after, India has been a leading producer and exporter of tea globally. Its production consistently exceeded domestic consumption, making it a net exporter. While India is largely self-sufficient in foodgrains, it is a net importer of petroleum to meet its substantial energy needs. Petrochemicals production meets some domestic demand but also involves imports for certain products.

Explanation

The Narmada and Tapti (also known as Tapi) are two of the most significant west-flowing rivers in peninsular India. They originate in the central part of the country and flow westward into the Arabian Sea, forming estuaries. In contrast, the Rapti River is a tributary of the Ghaghara River, which itself flows into the Ganga River. The Rapti generally flows in an eastward or southeastward direction through Nepal and Uttar Pradesh, making it an east-flowing river. Therefore, only Narmada and Tapti flow west.

It was established in 1958 as the Central Public Health Engineering Research Institute (CPHERI) and was renamed NEERI in 1974. Its headquarters and main campus are located in Nagpur, Maharashtra, where it conducts extensive research on environmental science and engineering.

Explanation

As of 1999, Bihar included the territory that would later become the state of Jharkhand in November 2000. Therefore, the undivided Bihar bordered four Indian states: Uttar Pradesh to the west, Madhya Pradesh to the southwest, Orissa (now Odisha) to the southeast, and West Bengal to the east. It also shared an international border with Nepal to the north.

Explanation

According to the Census of India 1991, the decadal population growth rate for Bihar during the period 1981-1991 was 23.54%. This figure reflects the demographic changes and trends prevalent in the state during that decade.

Explanation

In 1999, Bihar included the present-day state of Jharkhand, which is exceptionally rich in coal reserves and production. Therefore, the undivided state of Bihar (Bihar + Jharkhand) was the leading coal-producing state in India at that time. It was followed by Madhya Pradesh and then West Bengal in terms of coal production volumes.

Explanation

Among the given options, National Highway No. 22 (NH 22) was a significant national highway that crossed through the state of Bihar in 1999. NH 22 connected Mohania in Rohtas district to Patna, the capital city of Bihar, serving as a crucial artery within the state.

Explanation

TISCO, the Tata Iron and Steel Company (now Tata Steel), is located in Jamshedpur, which falls within the Singhbhum district of Jharkhand. Historically and traditionally, the primary source of iron ore for TISCO has been from the rich iron ore mines situated in the Singhbhum district itself, such as Noamundi and Gua. This proximity to the raw material was a key factor in the plant's location and its sustained operation, especially in 1999.

Explanation

Jamshedpur was a significant industrial city in undivided Bihar. Prior to the bifurcation of Bihar and the creation of Jharkhand in 2000, Jamshedpur was one of the largest urban centers within the state. Its large population and extensive industrial infrastructure, particularly around Tata Steel, made it a prominent and major city in the region, exceeding the other options in terms of urban spread and population at that time.

Explanation

The Damodar River is historically known as the 'Sorrow of Bengal' because of the destructive floods it caused in the plains of West Bengal. The river originates in the Chota Nagpur Plateau region, which was located in the southern part of undivided Bihar at the time of this question (now in Jharkhand). Its seasonal flooding and the subsequent efforts to control it through the Damodar Valley Corporation highlight its historical significance.

Explanation

According to the Census of India 1991, Uttar Pradesh was the most populous state in India. Bihar ranked second in terms of population at that time, with approximately 8.63 crore people. Maharashtra followed in the third position, and West Bengal was fourth among the major states. This demographic distribution made Bihar the second most populous state in India prior to the creation of Jharkhand.

Explanation

Before Jharkhand was carved out in November 2000, Bihar's coal-based thermal power stations included Barauni Thermal Power Station in Begusarai, Chandrapura Thermal Power Station, and Bokaro Thermal Power Station. Panchet is a hydroelectric dam on the Damodar river, not a coal-based thermal plant. Santaldih Thermal Power Station is located in Purulia, West Bengal, and was never part of Bihar. The three correct coal-based thermal stations of pre-2000 Bihar are Barauni, Chandrapura, and Bokaro.

Explanation

In the late 20th century, particularly during the 1990s, Bihar experienced significant social and political unrest marked by the rise of private caste armies, often referred to as 'senas'. These groups, formed along caste lines, engaged in widespread violence and massacres, which were often characterized as casteist terrorism. This phenomenon was a dominant feature of Bihar's political and social landscape, especially in its central plains, and contributed to severe law and order challenges in the state.

Explanation

In 1999, before the bifurcation of Bihar and the creation of Jharkhand, the region was home to significant heavy industries. While major steel plants like Bokaro Steel Plant were located in Bokaro and Tata Steel in Jamshedpur, Dhanbad was a prominent industrial hub known for its extensive coal mines, which are crucial for steel production. Although not the direct site of a primary steel plant, Dhanbad formed part of the broader industrial belt in undivided Bihar that supported and was closely associated with the steel industry.

Explanation

In 1999, Ranchi, which was then part of undivided Bihar, was home to a prominent institution for mental health care. The Central Institute of Psychiatry (CIP), located in Kanke, Ranchi, was established in 1918 and was historically referred to as a "lunatic asylum" or mental hospital. It served as a major center for psychiatric treatment in the region.

Explanation

The PIO (Person of Indian Origin) Card scheme was introduced in 1999 for people of Indian Origin who held foreign passports and resided abroad.

Explanation

In 1999, and for several years prior, the pricing of petroleum products like diesel in India was often linked to international crude oil prices, even under an administered pricing mechanism. When global crude oil prices increased, domestic fuel prices were typically revised upwards to reflect these international market dynamics and to manage the oil import bill. Option C, "Price assessment as per International price level, which is the same as the last government," indicates that the recent price increase was due to adjusting domestic prices in line with global price trends, a policy approach that often showed continuity across different governments.

Explanation

In 1999, Bihar faced severe challenges regarding poverty, with a large proportion of its population living below the poverty line. This complex issue was attributable to multiple interconnected factors. The failure of effective land reforms (A) led to continued agrarian inequalities and landlessness. A lack of strong political will (B) often hampered the implementation of development policies and poverty alleviation programs. Furthermore, a large number of labor classes (C), particularly in the unorganized agricultural sector, faced low wages, underemployment, and lack of social security, contributing significantly to widespread poverty. Therefore, all these factors collectively contributed to the high incidence of poverty in Bihar.

Explanation

The World Bank Group consists of five international organizations: the International Bank for Reconstruction and Development (IBRD), the International Development Association (IDA), the International Finance Corporation (IFC), the Multilateral Investment Guarantee Agency (MIGA), and the International Centre for Settlement of Investment Disputes (ICSID). The International Monetary Fund (IMF) is a distinct international organization, though it is often referred to as a "sister institution" to the World Bank due to their common origin at the Bretton Woods Conference and their close collaboration on global financial stability and development. Therefore, the IMF is not a part of the World Bank Group.

Explanation

The Narasimham Committee, particularly its first report in 1991 (Committee on the Financial System) and its second report in 1998 (Committee on Banking Sector Reforms), recommended extensive reforms in India's financial sector.

Explanation

As of 1999, India had adopted full convertibility of the Indian Rupee on the current account. This measure was introduced in August 1994, allowing free inflows and outflows of foreign exchange for all current account transactions such as trade in goods and services, remittances, and interest payments. However, the capital account convertibility remained partial and subject to restrictions at that time.

Explanation

MODVAT (Modified Value Added Tax) was a system introduced in India in 1986, designed to replace the cascading effect of Central Excise Duties. It allowed manufacturers to claim credit for the excise duty paid on inputs and capital goods against the excise duty payable on their final products, thereby reducing the tax burden and promoting efficiency. While the question's specific effective date of April 2001 might refer to a particular extension or the transition to CENVAT (which replaced MODVAT), MODVAT's core function was always in relation to Central Excise Duties.

Explanation

Regional Rural Banks (RRBs) are financial institutions established with the objective of providing credit and other banking facilities to small and marginal farmers, agricultural labourers, and artisans in rural areas. They are classified as Scheduled Commercial Banks because they are included in the Second Schedule of the Reserve Bank of India Act, 1934. This inclusion grants them certain privileges and subjects them to RBI's regulatory framework.

Explanation

First, calculate the cost price (CP) of the cycle. Given that the selling price (SP1) is ₹ 450 and there's a 20% loss, SP1 = CP - (0.20 CP) = 0.80 CP. So, CP = 450 / 0.80 = ₹ 562.50. To find the selling price (SP2) with a 20% profit, SP2 = CP + (0.20 CP) = 1.20 CP. Therefore, SP2 = 1.20 * 562.50 = ₹ 675.

Explanation

For a relation to be a function from set A to set B (f: A -> B), every element in the domain set A must be mapped to exactly one element in the codomain set B. In this case, the domain is x,y,z and the codomain is a,b. The given definition of f = (x,a), (y,b) maps x to a and y to b, but the element 'z' from the domain is not mapped to any element in the codomain. Since 'z' does not have an image, f does not satisfy the definition of a function.

Explanation

The compound interest (CI) can be calculated using the formula CI = P(1 + R/100)T - P, where P is the principal amount, R is the annual rate of interest, and T is the time in years. Given P = ₹ 4000, R = 5%, and T = 2 years. First, calculate the amount (A) after 2 years: A = 4000 (1 + 5/100)² = 4000 (1.05)² = 4000 * 1.1025 = ₹ 4410. The compound interest is then A - P = 4410 - 4000 = ₹ 410.

Explanation

Pi (π) is a mathematical constant representing the ratio of a circle's circumference to its diameter. It is universally recognized as an irrational number, meaning it cannot be expressed as a simple fraction (p/q) and its decimal representation extends infinitely without repetition.

Explanation

The given expression is in the form of (a³ - b³) / (a² + ab + b²). We know the algebraic identity a³ - b³ = (a - b)(a² + ab + b²). Substituting this into the expression, we get [(a - b)(a² + ab + b²)] / (a² + ab + b²). This simplifies to (a - b). Here, a = 0.05 and b = 0.04. Therefore, the value of the expression is 0.05 - 0.04 = 0.01.

Explanation

Let the original radius of the circle be r. The problem states "half-diameter" which is synonymous with radius. "Increased by twotimes" means the new radius is two times the original, i.e., 2r. The original area of the circle is Aₒld = pi r². The new radius is rₙew = 2r. The new area is Aₙew = pi (rₙew)² = pi (2r)² = 4 pi r². The increase in area is Aₙew - Aₒld = 4 pi r² - pi r² = 3 pi r². The percentage of increased area is (Increase in Area / Original Area) 100 = (3 pi r² / (pi r²)) 100 = 3 100 = 300%.

Explanation

For a system of two linear equations, A1x + B1y = C1 and A2x + B2y = C2, to have no solution, the lines must be parallel and distinct. This condition is met when the ratio of coefficients of x and y are equal, but not equal to the ratio of the constants: A1/A2 = B1/B2 != C1/C2. For the given equations: 2x + ay = 1 and 3x - 5y = 7, we have A1=2, B1=a, C1=1 and A2=3, B2=-5, C2=7. Setting A1/A2 = B1/B2: 2/3 = a/(-5). Cross-multiplying gives 3a = -10, so a = -10/3. Checking the constants ratio: C1/C2 = 1/7. Since 2/3 is not equal to 1/7, the condition for no solution is satisfied for a = -10/3.

Explanation

The "half-radius" means the radius of the circle. So, the radius (r) is 7 cm. The angle of the sector (theta) is 120 degrees. The formula for the area of a sector is (theta / 360°) pi r². Substituting the given values: Area = (120 / 360) (22/7) (7)². Area = (1/3) (22/7) 49. Area = (1/3) 22 7. Area = 154 / 3. Area approximately equals 51.33 cm².

Explanation

Given sets are X = a, b, Y = 2, 3, and Z = 3, 4. First, we need to find the intersection of sets Y and Z, denoted as Y interset Z. The common elements between Y and Z is 3. So, Y interset Z = 3. Next, we need to find the Cartesian product of X and (Y interset Z), which is denoted as X x (Y interset Z). This means forming ordered pairs where the first element is from X and the second element is from (Y interset Z). The elements of the Cartesian product will be (a, 3), (b, 3).
