The Constitution of Pakistan QUESTION #9353

Under Article 47, removal of the President by impeachment requires a resolution passed at a joint sitting by what fraction of total membership?

Simple majority
Two-thirds✔️
Three-fourths
Absolute majority of each House separately

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 — but the final removal requires two-thirds of the joint total.

Math (Module-1) QUESTION #5470

Question 382

Line $t$ in the $xy$-plane has slope $-\frac{1}{3}$ and passes through $(9, 10)$. Which equation defines line $t$?

$y = \frac{1}{3}x - 13$
$y = 9x + 10$
$y = -\frac{x}{3} + 10$
$y = -\frac{x}{3} + 13$✔️

Correct Answer Logic:

$y - 10 = -\frac{1}{3}(x - 9) \implies y = -\frac{1}{3}x + 3 + 10 \implies y = -\frac{1}{3}x + 13$.

Agronomy QUESTION #2042

Question 383

Vermicompost differs from conventional FYM in that:

It has lower nutrient content and slower release rates
It is processed through earthworm digestion, resulting in finer particle size, higher microbial activity, better nutrient availability, plant growth hormones, and humic acids compared to conventional composting✔️
It can only be applied as a liquid foliar spray
It increases soil acidity more rapidly than FYM

Correct Answer Logic:

Earthworms (Eisenia fetida) physically and biochemically transform organic matter during vermicomposting. The product has higher N (1.5–2.5%), better C:N ratio, richer microbial diversity, plant hormones (auxins, gibberellins), humic/fulvic acids, and finer texture than FYM — resulting in better crop response per unit weight applied.

Physics 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.

$16 : 9$
$25 : 9$✔️
$4 : 1$
$5 : 3$

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 $\frac{I_1}{I_2} = \left( \frac{a_1}{a_2} \right)^2 = \frac{25}{9}$.

Law QUESTION #9510

Question 390

A judgment is pronounced by the trial Court on 1 March 2023. The formal decree is drawn up and signed on 15 April 2023. An appeal is filed on 25 March 2023, i.e., after judgment but before the formal decree. The respondent contends the appeal is premature and incompetent. Is this objection valid?

No; the appellate Court should wait until the formal decree is ready before hearing the appeal
No; under Section 96 CPC, an appeal lies from a decree, and the date of the decree is the date of the judgment; the formal decree, once drawn, relates back to the date of the judgment. An appeal filed after judgment but before formal drawing of the decree is valid✔️
Yes; an appeal can only be filed after the decree is formally drawn up and signed
Yes; limitation for appeal runs from the date the decree is signed

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.

Chemistry QUESTION #5523

Question 391

Identify the reaction that is NOT part of the ozone layer depletion mechanism in the stratosphere.

$CF_2Cl_2(g) \xrightarrow{hv} \cdot Cl(g) + \cdot CF_2Cl(g)$
$Cl\dot{O}(g) + O(g) \rightarrow \cdot Cl(g) + O_2(g)$
$CH_4 + 2O_3 \rightarrow 3\,CH_2{=}O + 3H_2O$✔️
$HOCl(g) \xrightarrow{hv} \cdot OH(g) + \cdot Cl(g)$

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 — 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.

Education QUESTION #6766

Question 392

When scoring essay examinations, a teacher reads each complete paper fully before assigning an overall grade, sorting papers into piles (A/B/C/D/F). No sub-scores are given for specific elements. This approach reflects which scoring method, and what is its MOST significant advantage over the alternative?

Analytic rubric; provides more detailed feedback per criterion
Holistic scoring rubric; enables quicker scoring and is most appropriate when no single pre-specified correct answer exists, such as in synthesis and evaluation tasks✔️
Inter-rater scoring; maximizes consistency between two scorers
Criterion-referenced scoring; ensures all students are compared to the same absolute standard

Correct Answer Logic:

The described procedure — reading the full response and assigning a single overall score without breaking it into criteria — 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.

Quantitative Reasoning 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.

diversity✔️
deviation
reproduction
stability

Correct Answer Logic:

The sentence says carbon can form an unending series of different molecules — 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

Large tomb
Waiting period✔️
Security for debt
Funeral house

Correct Answer Logic:

Moratorium means a temporary prohibition or suspension of an activity. Its antonym is 'waiting period' — 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.

Physics 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]

$V^{-2}A^{2}F^{-2}$
$V^{-2}A^{2}F^{2}$
$V^{-4}A^{-2}F$
$V^{-4}A^{2}F$✔️

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].
