Limonite is an important iron ore, primarily consisting of hydrated iron(III) oxide-hydroxides, often found in bog and swamp environments. It is a common ore for extracting iron due to its relatively high iron content and ease of processing. In contrast, Bauxite is the primary ore for aluminum, and Cinnabar is the main ore for mercury. While Pyrite contains iron, it is primarily a sulfide mineral and not typically processed as a main source of iron ore.

Which type of rock is formed from cooling and solidification of lava?
● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (B) Igneous
Explanation
Igneous rocks are formed directly from the cooling and solidification of molten rock material. When this molten rock is below the Earth's surface, it is called magma, and the resulting rocks are intrusive igneous rocks. When the molten rock erupts onto the Earth's surface as lava, it cools and solidifies to form extrusive igneous rocks. This process distinguishes them from sedimentary rocks, which form from compacted sediments, and metamorphic rocks, which form from existing rocks altered by heat and pressure.

● Correct

Answer: (D) i, ii and iv
Explanation
Dalton's atomic theory, proposed in the early 19th century, successfully provided a theoretical basis for several fundamental chemical laws. It explained the Law of Conservation of Mass by stating that atoms are merely rearranged in chemical reactions, not created or destroyed. It also accounted for the Law of Constant Composition (or Definite Proportions) by assuming compounds are formed from fixed ratios of atoms. Furthermore, it led to the formulation of the Law of Multiple Proportions. However, the Law of Radioactivity, which involves nuclear transformations, was discovered much later and is not explained by Dalton's theory.

For ORUX: O(15) -> R(18) is +3, R(18) -> U(21) is +3, U(21) -> X(24) is +3. The pattern is (3, 3, 3).
For JMPS: J(10) -> M(13) is +3, M(13) -> P(16) is +3, P(16) -> S(19) is +3. The pattern is (3, 3, 3).
For CFIL: C(3) -> F(6) is +3, F(6) -> I(9) is +3, I(9) -> L(12) is +3. The pattern is (3, 3, 3).
Since PSVX follows a different pattern (3, 3, 2) compared to the others (3, 3, 3), it is the distinct group.

Answer: (D) i and iv
Explanation
Exothermic processes are those that release energy, typically in the form of heat. The combustion of methane (1) is a classic example of an exothermic reaction, where methane burns to produce carbon dioxide and water, releasing substantial heat. The formation of water from hydrogen and oxygen (4) is also a highly exothermic reaction, as energy is released when the H-O bonds are formed. In contrast, the decomposition of water (2) requires energy input and is endothermic. The dissolution of salt in water (3) can be either exothermic or endothermic depending on the specific salt, but options 1 and 4 are definitively and strongly exothermic.

Explanation
The Constitution of India is divided into various parts addressing different aspects. Part I deals with the Union and its Territory. Part II covers Citizenship. Part III outlines Fundamental Rights, and Part IV contains the Directive Principles of State Policy. Therefore, matching List I items to their respective parts in List II: The Fundamental Rights are in Part III (c), The Directive Principles of State Policy are in Part IV (d), and The Citizenship is in Part II (a). Assuming "The Constitution" refers generally to the foundational structure, aligning with Part I (b), the correct mapping sequence of List II indices for List I items (1, 2, 3, 4) is (2, 3, 4, 1), which corresponds to option B.

Under Article 200 of the Indian Constitution, the Governor has several options when a bill is passed by the State Legislature and presented to them. They can assent to the bill, withhold assent, or in the case of a bill that is not a Money Bill, return it to the State Legislature for reconsideration. The Constitution does not prescribe a specific time limit within which the Governor must return the bill for reconsideration. This means the Governor can effectively delay a bill indefinitely by not taking action, which is referred to as a 'pocket veto'.

● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (B) Low temperature, high pressure
Explanation
For a gas to be converted into its liquid state, or liquefied, its molecules must be brought closer together and their kinetic energy must be reduced. This is achieved by applying high pressure, which forces the gas molecules into a smaller volume, and simultaneously lowering the temperature, which reduces the kinetic energy of the molecules. These conditions allow intermolecular forces to become significant enough to hold the molecules in a liquid state.

If February 1, 1996 is Wednesday, what day is March 3, 1996?
● Correct

Show answer & explanationHide answer⌄
Answer: (D) Saturday
Explanation
To determine the day of the week, first identify the number of days between February 1, 1996, and March 3, 1996. Since 1996 is a leap year (divisible by 4), February has 29 days.
Days remaining in February: 29 - 1 = 28 days.
Days in March: 3 days.
Total days = 28 + 3 = 31 days.
Now, divide the total days by 7 to find the remainder: 31 / 7 = 4 weeks and 3 days remainder.
Starting from Wednesday, count forward 3 days:
Wednesday + 1 day = Thursday
Wednesday + 2 days = Friday
Wednesday + 3 days = Saturday.
Therefore, March 3, 1996, is a Saturday.

The triangular commerce between India, China, and England during the 18th and 19th centuries was primarily fueled by opium.

● Correct
● Not quite — the correct answer is highlighted

Explanation
The coding pattern for COMPUTER to RFUVQNPC involves two steps. First, the original word is reversed. So, COMPUTER becomes RETUPMOC. Second, the first and last letters of this reversed word remain unchanged (R and C), while all the intermediate letters are shifted one position forward in the alphabet (E+1=F, T+1=U, U+1=V, P+1=Q, M+1=N, O+1=P). Applying this rule to MEDICINE: reverse it to ENICIDEM. Keep the first 'E' and last 'M' unchanged. Shift the middle letters: N becomes O, I becomes J, C becomes D, I becomes J, D becomes E, E becomes F. This results in the coded word EOJDJEFM.

What is the 14th term of the sequence 14, 10, 6, 2,...?
● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (C) - 38
Explanation
The given sequence 14, 10, 6, 2,... is an arithmetic progression. The first term (a) is 14. The common difference (d) can be found by subtracting any term from its preceding term, which is 10 - 14 = -4. To find the 14th term (a₁4), we use the formula for the nth term of an arithmetic progression: aₙ = a + (n-1)d. Substituting the values, we get a₁4 = 14 + (14-1)(-4) = 14 + (13)(-4) = 14 - 52 = -38.

● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (A) Comet
Explanation
Comets are celestial bodies characterized by their highly eccentric, or elongated elliptical, orbits around the Sun. These orbits often take them from the outer reaches of the solar system, such as the Oort Cloud or Kuiper Belt, close to the Sun, and then back out again. Asteroids, in contrast, typically have more circular orbits primarily within the asteroid belt between Mars and Jupiter. Meteors and meteorites are not distinct celestial bodies with characteristic orbits, but rather fragments that enter Earth's atmosphere or land on its surface.

● Correct
● Not quite — the correct answer is highlighted
Show answer & explanationHide answer⌄
Answer: (C) 22
Explanation
In a 12-hour period, the hour and minute hands of a clock coincide 11 times. This is because while they generally coincide once every hour, there is only one coincidence (at 12 o'clock) between 11 o'clock and 1 o'clock (a two-hour period), effectively losing one coincidence. Therefore, over a full day, which is 24 hours, the hands will coincide 11 times in the first 12 hours and another 11 times in the next 12 hours, totaling 22 times.

The tesla (T) is the SI derived unit of magnetic field strength (B). It can be defined from the Lorentz force law, F = qvB, or from the force on a current-carrying wire in a magnetic field, F = BIL, where F is force, I is current, and L is length. From F = BIL, we can derive B = F / (IL). Substituting the SI units, this gives Tesla = Newton / (Ampere × meter).
