QUESTION #9353
Question 381
Under Article 47, removal of the President by impeachment requires a resolution passed at a joint sitting by what fraction of total membership?
Correct Answer Logic:
Article 47(8) requires that a resolution declaring the President unfit or guilty 'shall be passed at the joint sitting by the votes of not less than two-thirds of the total membership of Majlis-e-Shoora (Parliament).' The notice to initiate proceedings requires only half of one House โ but the final removal requires two-thirds of the joint total.

Question 382
Line $t$ in the $xy$-plane has slope $-\frac{1}{3}$ and passes through $(9, 10)$. Which equation defines line $t$?
Correct Answer Logic:
$y - 10 = -\frac{1}{3}(x - 9) \implies y = -\frac{1}{3}x + 3 + 10 \implies y = -\frac{1}{3}x + 13$.

Question 383
Vermicompost differs from conventional FYM in that:
Correct Answer Logic:
Earthworms (Eisenia fetida) physically and biochemically transform organic matter during vermicomposting. The product has higher N (1.5โ2.5%), better C:N ratio, richer microbial diversity, plant hormones (auxins, gibberellins), humic/fulvic acids, and finer texture than FYM โ resulting in better crop response per unit weight applied.

QUESTION #7025
Question 386
Two coherent waves interfere, resulting in a ratio of maximum to minimum intensity of $16$. Determine the ratio of the individual wave intensities.
Correct Answer Logic:
$\frac{I_{max}}{I_{min}} = \left( \frac{a_1 + a_2}{a_1 - a_2} \right)^2 = 16 \implies \frac{a_1 + a_2}{a_1 - a_2} = 4$.
$a_1 + a_2 = 4a_1 - 4a_2 \implies 5a_2 = 3a_1 \implies \frac{a_1}{a_2} = \frac{5}{3}$.
Intensity ratio $\frac{I_1}{I_2} = \left( \frac{a_1}{a_2} \right)^2 = \frac{25}{9}$.

Which continent is located on the Tropic of Cancer, the Tropic of Capricorn, and the Equator?
Correct Answer Logic:
Section 2(2) CPC defines a decree as a formal expression of adjudication. A decree relates to the judgment which precedes it. Under Order XX CPC, the decree follows from the judgment. Limitation for appeal runs from the date of decree (i.e., the date of judgment). An appeal filed after judgment is not premature even if the formal decree has not been drawn.

Question 391
Identify the reaction that is NOT part of the ozone layer depletion mechanism in the stratosphere.
Correct Answer Logic:
The ozone depletion cycle involves: (A) CFCs releasing Cl radicals under UV, (B) ClO reacting with O atom to regenerate Cl radical (chain propagation), (D) HOCl photolysis to give OH and Cl radicals โ all are real steps. Option (C), the reaction of $CH_4$ with $O_3$ to give formaldehyde and water, is NOT a recognized step in stratospheric ozone depletion chemistry.

Correct Answer Logic:
The described procedure โ reading the full response and assigning a single overall score without breaking it into criteria โ is holistic scoring. Its key advantage is efficiency (quicker to score) and appropriateness for extended-response tasks involving synthesis and evaluation, where performance is a gestalt that is difficult to decompose into discrete point-scoring elements.

QUESTION #8134
Question 397
Some researchers argue that carbon compounds are so central to life on Earth due to the possibility of _______ arising from the carbon atom's capacity to form an endless variety of different molecules.
Correct Answer Logic:
The sentence says carbon can form an unending series of different molecules โ this chemical versatility leads to diversity of life forms. Carbon's ability to create countless molecule types is precisely what generates biological variety. 'Variety' is the synonym pair in the original exam. 'Deviation' implies abnormality. 'Reproduction' refers to biological copying. 'Stability' is the opposite of variety.

Question 399
Correct antonym of "MORATORIUM" is
Correct Answer Logic:
Moratorium means a temporary prohibition or suspension of an activity. Its antonym is 'waiting period' โ however, moratorium itself means a pause/delay, so the answer here points to 'waiting period' as the closest contextual opposite implying continuation rather than suspension.

QUESTION #7102
Question 400
Using speed ($V$), acceleration ($A$), and force ($F$) as fundamental units, what is the dimension of Young's modulus? [cite: 476]
Correct Answer Logic:
Young's modulus has the same dimensions as pressure: $[M L^{-1} T^{-2}]$.
- $[F] = [M L T^{-2}]$
- $[V] = [L T^{-1}]$
- $[A] = [L T^{-2}]$
- By solving $Y = F^a V^b A^c$, we find $a=1, b=-4, c=2$[cite: 480].
