Answer: (A) watershed

Explanation

A watershed is a topographically delineated area of land that acts as a natural geo-hydrological unit by collecting all precipitation within its boundaries and funneling it through a network of streams to a single common outlet. The boundary of a watershed is defined by the highest elevations surrounding a drainage area, known as the drainage divide, which ensures that all surface runoff and groundwater flow originating within the perimeter converge at a specific discharge point. This integrated system allows for the comprehensive management of water, soil, and biological resources, making it the fundamental unit for hydrological modeling and ecological conservation efforts.

Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) Stagflation

Explanation

Stagflation is a portmanteau of stagnation and inflation, describing an economic condition where the growth rate slows, the unemployment rate remains steadily high, and the price levels of goods and services continue to rise. This scenario is particularly challenging for a country's central bank and fiscal authorities because traditional monetary and fiscal policies used to combat one issue often worsen the other. For instance, increasing interest rates to curb inflation can further suppress economic growth and increase unemployment. It typically occurs due to supply-side shocks, such as a sudden rise in the cost of essential commodities like oil, which increases production costs while reducing consumer purchasing power and industrial output.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) Coral

Explanation

Corals are marine invertebrates belonging to the phylum Cnidaria. As sessile animals, they remain permanently attached to a substrate on the ocean floor for the duration of their adult lives. Reef-building corals maintain a critical mutualistic relationship with microscopic algae known as zooxanthellae that live within their tissues. Through photosynthesis, these algae provide the corals with essential nutrients and oxygen, which the coral polyps use to secrete calcium carbonate. Over vast periods, the accumulation and cementing of these calcium carbonate skeletons result in the formation of massive coral reefs. These reefs represent the largest structures of biological origin on Earth, extending for thousands of kilometers and providing habitats for a significant portion of marine biodiversity.

Show answer & explanationHide answer

Answer: (D) Tonometer

Explanation

A tonometer is a medical diagnostic instrument used by eye care professionals to determine the intraocular pressure (IOP), which is the fluid pressure inside the eye. Measuring intraocular pressure is a fundamental part of a comprehensive eye examination and is the primary screening method for glaucoma, a condition where increased pressure can damage the optic nerve and lead to permanent vision loss. The measurement is typically recorded in millimeters of mercury (mmHg). The Goldmann applanation tonometer is the most widely used version and is considered the clinical gold standard; it operates on the Imbert-Fick principle, calculating the pressure based on the force required to flatten a constant area of the cornea. Other types include non-contact tonometers, which use a puff of air to measure the eye's resistance, and electronic indentation tonometers.

What do you call a proportionate saving in costs gained by an increased level of production?
Tap an option to check yourself

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (B) Economies of scale

Explanation

Economies of scale refer to the cost advantages that a business obtains due to its scale of operation, where the cost per unit of output generally decreases as the scale of production increases. This occurs because fixed costs, such as administrative expenses or machinery investment, are spread over a larger number of units. Mathematically, if TC represents the total cost and Q represents the quantity of output, the average cost AC is given by AC = (TC)/(Q). As Q increases, the average fixed cost component of TC declines, leading to a reduction in AC. Additionally, increased production levels often allow for greater specialization of labor, bulk purchasing discounts for raw materials, and the implementation of more efficient technological processes, all of which contribute to proportionate savings in total production costs.

The decision was taken during a virtual meeting of the board of trustees to fill the vacancy created by the death of the previous chairman, former Gujarat Chief Minister Keshubhai Patel, in October 2020. By accepting this role, Narendra Modi became the eighth chairman of the trust and the second Prime Minister of India to hold the position, after Morarji Desai. The Prime Minister had already been serving as one of the trustees of the temple for several years prior to his elevation to the chairmanship.

Answer: (B) Jonas Salk

Explanation

Jonas Salk developed the first successful polio vaccine, known as the inactivated poliovirus vaccine (IPV), in the early 1950s. Working at the University of Pittsburgh, Salk utilized a killed-virus method to stimulate the immune system to produce antibodies without the risk of causing the disease itself. Following one of the largest clinical trials in medical history involving nearly two million children, the vaccine was declared safe and effective on April 12, 1955. This breakthrough played a pivotal role in the global effort to eradicate paralytic poliomyelitis.

Answer: (A) Calamine

Explanation

Calamine is the traditional name applied to a natural admixture of two distinct zinc minerals: zinc carbonate (ZnCO₃), now known as smithsonite, and hydrous zinc silicate (Zn₄Si₂O₇(OH)₂ · H₂O), known as hemimorphite. Historically, these minerals were not distinguished from one another and were collectively referred to as calamine by miners and early mineralogists. They typically occur together in the oxidized portions of zinc ore deposits, formed through the weathering of primary zinc sulfide ores like sphalerite. While modern mineralogy uses specific names for the individual components, the term calamine persists in commercial and medicinal contexts to describe zinc-based ores and preparations.

Correct

Not quite — the correct answer is highlighted

Show answer & explanationHide answer

Answer: (C) Raman Effect

Explanation

The Raman Effect is the inelastic scattering of photons by molecules, resulting in a change in the energy and frequency of the light. When monochromatic light interacts with the molecules of a medium, the energy of the incident photons can be partially absorbed by the molecules, exciting them to higher vibrational or rotational energy levels. This results in scattered light with a lower frequency, known as Stokes radiation. Conversely, if the light interacts with a molecule already in an excited state, the molecule can transition to a lower energy level, transferring energy to the scattered photon and resulting in a higher frequency, known as anti-Stokes radiation. The energy difference between the incident and scattered light, Δ E = h(ᵢ - ₛ), corresponds directly to the quantized vibrational or rotational energy transitions of the specific molecules.
