Question 4

The physical appearance or observable characteristic of an organism is called its:

Allele
Genetic code
Genotype
Trait✔️

Correct Answer Logic:

Trait (or phenotype) is the physical expression (e.g., tall, dwarf). Genotype is the genetic makeup; allele is a variant form; genetic code is the triplet codon system.

Statistics QUESTION #2006

Question 5

A 99% confidence interval for the difference between two population proportions $p_1 - p_2$ uses the critical value $z_{\alpha/2}$ equal to:

1.645
1.960
2.326
2.576✔️

Correct Answer Logic:

For a 99% confidence interval, $\alpha = 0.01$ and $\alpha/2 = 0.005$. The corresponding standard normal critical value is $z_{0.005} = 2.576$. This is the value beyond which only 0.5% of the standard normal distribution lies in each tail.

HR and Management QUESTION #6451

Question 6

The statement 'Organizations depend on people, and without people, they would disappear' emphasizes:

People are replaceable organizational resources
Organizations are more important than individuals
Interdependence between organizations and people✔️
People control organizational outcomes completely

Correct Answer Logic:

This statement emphasizes the interdependence: HRM plays an important role in creating organizations and helping them survive, while organizations supply goods and services people depend on. Both need each other - neither can exist independently.

Physics QUESTION #7007

Question 7

A rectangular current loop (sides 10 cm and 5 cm, current $I = 12\ \text{A}$) is placed in a uniform magnetic field $B = 0.3\ \text{T}$ along $+z$. In which orientations is the loop in (i) stable equilibrium and (ii) unstable equilibrium?

(a) and (b) respectively
(a) and (c) respectively
(b) and (d) respectively✔️
(b) and (c) respectively

Correct Answer Logic:

Stable equilibrium: magnetic moment $\vec{m}$ is parallel to $\vec{B}$ (minimum energy, $U = -mB$).

Unstable equilibrium: $\vec{m}$ is antiparallel to $\vec{B}$ (maximum energy, $U = +mB$).

From the figures: In orientation (b), $\vec{m}$ is along $+z$ (parallel to $\vec{B}$) $\Rightarrow$ stable. In orientation (d), $\vec{m}$ is along $-z$ (antiparallel to $\vec{B}$) $\Rightarrow$ unstable. Answer: (b) and (d).

Question 8

What is the average of $\dfrac{1}{2},\ \dfrac{5}{6},\ \dfrac{3}{4},\ \dfrac{5}{12}$?

$\dfrac{7}{8}$
$\dfrac{2}{5}$
$\dfrac{5}{8}$✔️
$2\dfrac{1}{2}$

Correct Answer Logic:

Sum $= \dfrac{1}{2}+\dfrac{5}{6}+\dfrac{3}{4}+\dfrac{5}{12}$. L.C.M. of 2,6,4,12 is 12.
$= \dfrac{6}{12}+\dfrac{10}{12}+\dfrac{9}{12}+\dfrac{5}{12} = \dfrac{30}{12} = \dfrac{5}{2}$
Average $= \dfrac{5/2}{4} = \dfrac{5}{8}$

Physics QUESTION #4404

Question 9

A cannon is placed on a smooth surface. When it fires a shell, the cannon moves backward. This recoil occurs due to:

Law of conservation of energy
Backward thrust of the gases
Newton's third law of motion✔️
Newton's first law of motion

Correct Answer Logic:

When the cannon fires a shell forward, by Newton's third law, the shell exerts an equal and opposite reaction force on the cannon backward. This causes the cannon to recoil.

Question 10

The 'Saturation Temperature' of steam is:

The temperature at which it starts to freeze
The temperature at which water and steam coexist at a given pressure✔️
Always $200^\circ\text{C}$

Law QUESTION #9513

Question 11

A and B are parties to a civil suit. After the Court records evidence and hears arguments, it reserves judgment. Before pronouncing judgment, the presiding Judge is transferred. The new Judge wants to rehear the case from the beginning. A objects. Is the new Judge entitled to rehear the case from scratch?

No; only the original Judge can pronounce judgment
Yes; a new Judge must always start the trial afresh
Yes; all evidence must be re-recorded before the new Judge
No; the new Judge may pronounce judgment on the basis of the evidence recorded by his predecessor, though he may in his discretion rehear any part if he considers it necessary for justice✔️

Correct Answer Logic:

Order XVIII Rule 15 CPC provides that where a Judge is succeeded by another and the case has been partly heard, the new Judge may act on the evidence already recorded, though he may re-examine any witness if necessary. The case need not be reheard from the beginning unless the new Judge considers it essential for proper adjudication.

Civil / Architecture QUESTION #2371

Question 12

In the design of a retaining gravity wall, the factor of safety against overturning about the toe is computed as the ratio of the resisting moment $M_R$ to the overturning moment $M_O$. The minimum acceptable factor of safety against overturning per standard geotechnical practice is typically:

1.0
1.5✔️
2.0
3.0

Correct Answer Logic:

The minimum factor of safety against overturning for retaining walls is typically $FS_{OT} \geq 1.5$ per most codes and references (including Das, Bowles). The factor of safety against sliding is typically $FS_{sliding} \geq 1.5$, and against bearing capacity failure $FS_{BC} \geq 3.0$. Some codes require $FS_{OT} \geq 2.0$ for critical structures.

Education QUESTION #6780

Question 14

In a Table of Specification, after calculating that 25% of instructional time was devoted to Topic A, a teacher allocates 13 marks out of 50 total marks to Topic A. Is this allocation within acceptable limits?

No, the allocation must be exact — 12.5 marks and no rounding is permitted
Yes, the acceptable tolerance is ±2 percentage points; 13/50 = 26%, which is within ±2% of 25%✔️
No, the allocation should always round down to avoid over-testing any topic
Yes, but only if Topic A contains application-level questions

Correct Answer Logic:

The Table of Specification guideline states: Percent of instruction time = Percent of examination value (within ±2 percent). Topic A received 25% instructional time. Allocated: 13/50 = 26%. Since 26% is within ±2% of 25%, this is acceptable. If it were 28% or above (or 22% or below), revision would be needed.

Question 15

For a particle moving in a circular path of radius $R$ with constant speed $v$, the magnitude of total acceleration is:

$\frac{v^2}{R}$ directed toward the center✔️
$\frac{v}{R}$ tangentially
$\dot{v}$ only
$\sqrt{\dot{v}^2 + (v^2/R)^2}$ — always larger than $v^2/R$

Correct Answer Logic:

For constant speed circular motion, $\dot{v}=0$, so the tangential acceleration is zero. Only the normal (centripetal) acceleration exists: $a_n=v^2/R$, directed toward the center.

Library Sciences QUESTION #1516

Question 17

A bibliography that lists sources on a specific subject or by a specific author is classified as a:

Trade bibliography
Universal bibliography
Subject or personal bibliography✔️
National bibliography

Correct Answer Logic:

A subject bibliography lists works related to a particular topic or field, while a personal bibliography lists works by or about a specific individual. Both are distinguished from universal bibliographies (which aim to list all published works) and national bibliographies (which list works published in a country).

Chemistry QUESTION #7191

Question 18

The reaction of elemental sulfur ($S_{8}$) in an alkaline medium is represented by the equation: $S_{8(s)} + aOH_{(aq)}^{-} \rightarrow bS_{(aq)}^{2-} + cS_{2}O_{3(aq)}^{2-} + dH_{2}O_{(l)}$. Determine the stoichiometric coefficient 'a' required to balance this equation.

12✔️
6
8
10

Correct Answer Logic:

This is a disproportionation reaction. The balanced equation in alkaline medium is:

$S_{8} + 12OH^{-} \rightarrow 4S^{2-} + 2S_{2}O_{3}^{2-} + 6H_{2}O$

Therefore, the value of the coefficient 'a' is $12$.

Law QUESTION #9517

Question 19

A issues a notice to the Government under Section 80 CPC proposing to file a suit. The notice period has not expired when A files the suit. The Government pleader argues the suit is not maintainable. Is the suit premature?

Yes; Section 80 CPC requires a mandatory two-month notice to the Government before instituting a suit against it; filing before the expiry of the notice period renders the suit liable to rejection or stay until the notice period expires✔️
No; the Government can waive the notice
No; notice under Section 80 is merely directory
No; the Court can condone the premature filing

Correct Answer Logic:

Section 80 CPC mandates a two-month written notice before suing the Government or a public officer in respect of any act done in official capacity. This is a mandatory requirement; non-compliance renders the plaint liable to rejection. The suit cannot proceed until the notice period has elapsed, though urgent injunctive relief may be sought.
