Question 2

At which level of measurement can values be placed into categories that are rank-ordered along a continuum from high to low?

Interval
Ordinal✔️
Ratio
None of these

Correct Answer Logic:

The ordinal level of measurement allows data to be ranked or ordered (e.g., first, second, third; or high, medium, low), but the intervals between ranks are not necessarily equal. Examples include class rankings, Likert scale ratings, and educational grades as categories.

Correct Answer: B — Ordinal.

Question 7

Match List-I (Partial Derivatives) with List-II (Thermodynamic Quantities): (A) $\left(\dfrac{\partial G}{\partial T}\right)_P$ (B) $\left(\dfrac{\partial H}{\partial T}\right)_P$ (C) $\left(\dfrac{\partial G}{\partial P}\right)_T$ (D) $\left(\dfrac{\partial U}{\partial T}\right)_V$ with (I) $C_P$ (II) $-S$ (III) $C_V$ (IV) $V$

(A)-(II), (B)-(I), (C)-(III), (D)-(IV)

(A)-(II), (B)-(III), (C)-(I), (D)-(IV)

Correct Answer Logic:

Using thermodynamic relations: $\left(\frac{\partial G}{\partial T}\right)_P = -S$ (II). $\left(\frac{\partial H}{\partial T}\right)_P = C_P$ (I). $\left(\frac{\partial G}{\partial P}\right)_T = V$ (IV). $\left(\frac{\partial U}{\partial T}\right)_V = C_V$ (III). Matching: A-II, B-I, C-IV, D-III.

Psychology QUESTION #9837

Question 8

In Pavlovian conditioning, the learned response is the:

CS
CR✔️
UCS
UCR

Correct Answer Logic:

In classical conditioning, the CR (conditioned response) is the learned reaction — the acquired response to the CS alone after repeated CS-US pairings. The UCR is the natural, unlearned reaction to the UCS.

Accounting & Finance QUESTION #6215

Question 9

An auditor uses $n$ samples to test a population $N$. The limitation that audit evidence is 'Persuasive' rather than 'Conclusive' is primarily due to:

The use of testing and inherent limitations of internal controls✔️
The auditor's lack of professional skepticism
The requirement of the Companies Ordinance 1984
The use of KaTeX in mathematical reporting

Correct Answer Logic:

Reasonable assurance is limited because of the use of testing (sampling) and the persuasive nature of evidence, meaning it leads to an opinion rather than absolute proof.

The Constitution of Pakistan QUESTION #9359

Question 12

Under Article 209, the Supreme Judicial Council's function regarding judges includes which of the following that is NOT within its powers?

Inquiring into incapacity of a judge
Presenting a report to the President for removal of a judge
Directly removing a judge from office✔️
Giving a judge an opportunity to show cause before presentation of adverse findings

Correct Answer Logic:

Article 209 establishes the Supreme Judicial Council to inquire into incapacity or misconduct of judges. However, the Council does not itself remove judges — it reports to the President, who then acts on the report. Direct removal power lies with the President on the Council's recommendation, not with the Council itself.

Molecular Biology / Bioinformatics / Biochemistry QUESTION #11115

Question 13

Male breast cancer risk is most strongly linked with mutations in which gene?

BRCA1
BRCA2✔️
NF1
RET

Correct Answer Logic:

BRCA2 mutations are the most significant hereditary risk factor for male breast cancer. Men with BRCA2 mutations have a lifetime breast cancer risk of ~6–8% (vs ~0.1% in the general male population). BRCA2 mutations also increase risk of prostate and pancreatic cancer. While BRCA1 mutations also increase male breast cancer risk, the association is weaker. BRCA2 mutations account for the majority of hereditary male breast cancer cases (vs BRCA1, which predominantly affects female breast/ovarian cancer).

Question 14

The majority of carbon dioxide in the blood is transported as:

Dissolved CO$_2$ in plasma
Carbaminohemoglobin
Bicarbonate ions (HCO$_3^-$)✔️
Carbonic acid

Correct Answer Logic:

Approximately 70% of CO$_2$ is transported as bicarbonate ions (HCO$_3^-$) in the plasma. About 20-23% binds to hemoglobin as carbaminohemoglobin, and only 7-10% is dissolved in plasma.

Nursing QUESTION #9303

Question 15

A patient is suspected to have meningitis. The nurse performs a Kernig's sign test. Kernig's sign is positive when:

The patient's neck stiffens on passive flexion
The patient cannot straighten the knee when the hip is flexed at 90 degrees✔️
The pupil fails to react to light
Plantar flexion occurs on stroking the sole

Correct Answer Logic:

Kernig's Sign — assessment for meningeal irritation:

Position: Patient supine, flex hip and knee to 90 degrees
Attempt to extend (straighten) the knee
Positive sign: Resistance and pain on knee extension (patient cannot straighten leg) — indicates meningeal irritation/meningitis

Other signs of meningitis:

Sign	Test	Positive Finding
Brudzinski's sign	Passive neck flexion	Involuntary hip and knee flexion
Kernig's sign	Hip flexed, extend knee	Resistance/pain on extension
Nuchal rigidity	Passive neck flexion	Resistance/pain (stiff neck)

Classic triad of bacterial meningitis: fever, neck stiffness, altered consciousness.

Library Sciences QUESTION #1516

Question 16

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).

Question 17

The semantic differential scale is used mainly to measure:

Values
Opinions
Interests
Attitudes✔️

Maths QUESTION #2905

Question 18

Area of a triangle with base $10$ cm and height $5$ cm is:

$25\text{ cm}^2$✔️
$50\text{ cm}^2$
$15\text{ cm}^2$
$100\text{ cm}^2$

Correct Answer Logic:

Area $= \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 10 \times 5 = 25$.

Mathematics QUESTION #6939

Question 19

Let $S_n = 1+q+q^2+\cdots+q^n$ and $T_n = 1+\dfrac{q+1}{2}+\left(\dfrac{q+1}{2}\right)^2+\cdots+\left(\dfrac{q+1}{2}\right)^n$, where $q \in \mathbb{R},\ q\neq 1$. If ${}^{101}C_1 + {}^{101}C_2\cdot S_1 + \cdots + {}^{101}C_{101}\cdot S_{100} = \alpha\, T_{100}$, find $\alpha$.

$2^{99}$
202
200
$2^{100}$✔️

Correct Answer Logic:

$S_n = \dfrac{q^{n+1}-1}{q-1}$. The LHS sum involves $\sum_{k=1}^{101}\binom{101}{k}S_{k-1}$.

After substituting and applying binomial theorem: the sum simplifies using $\sum \binom{101}{k}\frac{q^k-1}{q-1}$.

The result evaluates to $\alpha T_{100}$ where $\alpha = 2^{100}$.
