Library Sciences QUESTION #1502

In verbal subject approaches, a pre-coordinated subject heading system combines multiple subject concepts at which stage?

At the time of searching
At the time of indexing✔️
At the time of acquisition
At the time of shelving

Correct Answer Logic:

Pre-coordination occurs at the time of indexing — the cataloguer combines multiple concepts into a single complex heading before the record is stored. Post-coordination allows users to combine terms at the time of searching.

Education QUESTION #6910

Question 4322

A school adopts a policy in which 'school-wide behavioral expectations are condensed into three to five positively stated, age-appropriate statements that are prominently displayed and consistently enforced.' This approach is MOST consistent with which framework?

Transactional Analysis applied at the institutional level
Effective Behavioral Support Systems and Social Competence culture-building✔️
Reality Therapy's emphasis on clear rules and plans
Assertive Discipline's consequence hierarchy

Correct Answer Logic:

This approach is the hallmark of Effective Behavioral Support (EBS) and social competence culture-building, which emphasize: (1) positively-framed expectations (e.g., 'Be respectful' not 'Don't insult'), (2) brevity for memorability, (3) age-appropriateness, and (4) school-wide visibility and consistency — all of which are key features of creating a school-wide culture of social competence.

MBBS QUESTION #10337

Question 4323

An individual's basal caloric requirement (basal metabolic rate) is primarily estimated based on:

Body surface area, age, sex, and lean body mass✔️
Height alone, independent of weight, age, sex, or activity
A single fixed value identical for every adult regardless of body size
Total dietary fat intake alone

Correct Answer Logic:

Basal metabolic rate correlates most closely with lean body mass (metabolically active tissue) and is further influenced by body surface area, age, and sex (e.g., males typically have a higher BMR than females at a similar body size due to greater lean mass) — the basis of standard BMR estimation formulas used in clinical nutrition.

Chemistry QUESTION #7110

Question 4324

Given the half-cell reactions:
1. $Mn^{2+} + 2e^{-} \rightarrow Mn$; $E^{0} = -1.18\text{ V}$
2. $Mn^{3+} + e^{-} \rightarrow Mn^{2+}$; $E^{0} = +1.51\text{ V}$
Determine the $E^{0}$ for the disproportionation reaction $3Mn^{2+} \rightarrow Mn + 2Mn^{3+}$ and its feasibility.

-0.33 V; non-spontaneous
-0.33 V; spontaneous
-2.69 V; non-spontaneous✔️
-2.69 V; spontaneous

Correct Answer Logic:

The target reaction is $3Mn^{2+} \rightarrow Mn + 2Mn^{3+}$. This is the sum of:
Reduction: $Mn^{2+} + 2e^{-} \rightarrow Mn$ ($E^{0}_{red} = -1.18\text{ V}$)
Oxidation: $2Mn^{2+} \rightarrow 2Mn^{3+} + 2e^{-}$ ($E^{0}_{ox} = -1.51\text{ V}$)
$E^{0}_{cell} = E^{0}_{cathode} - E^{0}_{anode} = -1.18 - 1.51 = -2.69\text{ V}$. Since $E^{0}_{cell}$ is negative, the reaction is non-spontaneous.

Reading and Writing (Module-1) QUESTION #5420

Question 4329

While researching a topic, a student has taken the following notes: • Chemical leavening agents cause carbon dioxide to be released within a liquid batter, making the batter rise as it bakes. • Baking soda and baking powder are chemical leavening agents. • Baking soda is pure sodium bicarbonate. • To produce carbon dioxide, baking soda needs to be mixed with liquid and an acidic ingredient such as honey. • Baking powder is a mixture of sodium bicarbonate and an acid. • To produce carbon dioxide, baking powder needs to be mixed with liquid but not with an acidic ingredient. The student wants to emphasize a difference between baking soda and baking powder. Which choice most effectively uses relevant information from the notes to accomplish this goal?

To make batters rise, bakers use chemical leavening agents such as baking soda and baking powder.
Baking soda and baking powder are chemical leavening agents that, when mixed with other ingredients, cause carbon dioxide to be released within a batter.
Baking soda is pure sodium bicarbonate, and honey is a type of acidic ingredient.
To produce carbon dioxide within a liquid batter, baking soda needs to be mixed with an acidic ingredient, whereas baking powder does not.✔️

Correct Answer Logic:

This choice directly contrasts the key difference: baking soda requires an acidic ingredient while baking powder doesn't.

Electrical Engineering QUESTION #2162

Question 4332

A 220 kV transmission line has surge impedance $Z_c = 250\,\Omega$. The Surge Impedance Loading (SIL) is:

$193.6\,\text{MW}$✔️
$96.8\,\text{MW}$
$387.2\,\text{MW}$
$484\,\text{MW}$

Correct Answer Logic:

$\text{SIL} = \frac{V_R^2}{Z_c} = \frac{(220 \times 10^3)^2}{250} = \frac{4.84 \times 10^{10}}{250} = 193.6\,\text{MW}$.

Administration QUESTION #9561

Question 4336

The Planning Commission's function includes appraisal of development projects before approval. What distinguishes 'project appraisal' from 'project feasibility study,' and at which stage in the project cycle does each occur?

Project feasibility is a desk review of existing data; project appraisal involves new data collection through field surveys — feasibility precedes preparation, appraisal follows it
Project feasibility is the in-depth technical, financial and economic study conducted before project preparation; project appraisal is the Planning Commission's independent review of the data and assumptions in the prepared project document — appraisal follows preparation✔️
Project feasibility determines whether a project is politically acceptable; project appraisal determines whether it is technically sound — both occur simultaneously before Cabinet approval
Project feasibility is conducted by the sponsoring department; project appraisal is conducted by the legislature's Public Accounts Committee after implementation

Correct Answer Logic:

The project cycle is: identification → feasibility (in-depth technical/financial/economic viability study) → preparation (filling PC-I form with project details) → appraisal (Planning Commission's independent verification of the PC-I data and assumptions) → approval → implementation → evaluation. Feasibility precedes preparation; appraisal follows it — they are distinct stages with different actors and purposes.

Verbal Reasoning QUESTION #8164

Question 4337

If $2x = 3y = 4z = 20$, what is the value of $12xyz$?

$16{,}000$
$8{,}000$
$4{,}000$✔️
$800$

Correct Answer Logic:

From $2x = 20$: $x = 10$.

From $3y = 20$: $y = \dfrac{20}{3}$.

From $4z = 20$: $z = 5$.

Now compute $12xyz$:

$12 \times 10 \times \dfrac{20}{3} \times 5 = 12 \times \dfrac{1000}{3} = \dfrac{12000}{3} = 4{,}000$

Law QUESTION #9486

Question 4338

A decree-holder A wishes to attach a sum of Rs. 500,000 kept in a bank account belonging to the judgment-debtor B, which was earned by B as salary and deposited over time. B argues that salary is exempt from attachment. Can the bank balance representing accumulated salary be attached?

Yes; once salary has been received and deposited in a bank account, it loses its character as salary and becomes an ordinary debt recoverable from the bank, which is attachable✔️
Yes; but only with the permission of the State Bank of Pakistan
No; bank accounts can never be attached in execution
No; salary retains its exempt character even after being deposited in a bank

Correct Answer Logic:

The exemption under Section 60(1)(i) CPC applies to salary before and until it is actually payable; once salary has been paid and deposited in a bank, it is converted into a debt due from the bank and loses its exempt character, becoming attachable in execution.

Dairy Food Science and Technology QUESTION #5994

Question 4340

In the production of lassi, the distinctive refreshing taste results from:

Addition of sugar and cream to fresh milk
Dilution of dahi (yoghurt) with water ($1:0.5\text{–}1:2$ ratio) producing a blend of lactic acid, acetaldehyde ($\approx 25\text{–}40\;\text{ppm}$), and diacetyl aromas in a lower-viscosity product✔️
Addition of synthetic flavorings to buttermilk
Fermentation of milk with kefir grains

Correct Answer Logic:

Lassi is made by blending dahi (yoghurt) with water and optionally sugar, salt, or spices. The characteristic flavor comes from fermentation metabolites: lactic acid (tart), acetaldehyde ($\approx 25\text{–}40\;\text{ppm}$, 'green/yoghurty' aroma), and diacetyl (buttery note). Dilution reduces viscosity and caloric density.
