Question 2

If $3.12 \text{ g}$ of oxygen gas is adsorbed on $1.2 \text{ g}$ of platinum metal, calculate the volume of oxygen adsorbed per gram of the adsorbent at $1 \text{ atm}$ and $300 \text{ K}$.

$1.0 \text{ L}$
$2.0 \text{ L}$✔️
$1.5 \text{ L}$
$2.5 \text{ L}$

Correct Answer Logic:

Calculate total volume of $O_{2}$ using $PV=nRT$:

Moles of $O_{2} = 3.12 / 32 = 0.0975 \text{ mol}$
$V = \frac{0.0975 \times 0.0821 \times 300}{1} \approx 2.4 \text{ L}$
Volume per gram of adsorbent = Total Volume / Mass of Pt
$2.4 \text{ L} / 1.2 \text{ g} = 2.0 \text{ L/g}$

Question 4

The volume of a cuboid is $840 \text{ cm}^3$. Its length is 12 cm and breadth is 7 cm. Find its height.

10 cm✔️
12 cm
14 cm
15 cm

Correct Answer Logic:

Volume of cuboid $= l \times b \times h$. $840 = 12 \times 7 \times h = 84h$. $h = \dfrac{840}{84} = 10$ cm.

Question 5

Choose the word that is most nearly opposite in meaning to BOYCOTT

extort
underwrite
underbid
patronize✔️

Correct Answer Logic:

Federal Rules of Evidence (US) QUESTION #3783

Question 6

A defendant is charged with embezzlement. He calls a character witness to testify that the defendant has a reputation in the community for being 'an honest and law-abiding man.' The prosecution seeks to cross-examine this witness by asking, 'Are you aware that the defendant was fired from his last job for stealing from the cash register?' Is this question allowed?

No, because specific instances of conduct are generally inadmissible under Rule 405.
Yes, because the prosecution can use specific instances of conduct to test a character witness's knowledge on cross-examination.✔️
No, unless the prosecution has a certified copy of a conviction for that theft.
Yes, but the prosecution must prove the theft by extrinsic evidence if the witness denies knowing about it.

Correct Answer Logic:

Rule 405(a) allows the prosecution to inquire into relevant specific instances of the person's conduct during cross-examination of a character witness to test the witness's credibility and the basis for their opinion/reputation testimony.

Question 7

A reinforced concrete beam is subjected to a factored moment $M_u$. If the beam is designed as 'tension-controlled' according to ACI 318, what is the minimum net tensile strain $\epsilon_t$ in the extreme tension steel at the nominal strength?

0.002
0.003
0.004
0.005✔️

Correct Answer Logic:

According to ACI 318, a section is tension-controlled if the net tensile strain in the extreme tension steel is equal to or greater than 0.005 when the concrete in compression reaches its assumed strain limit of 0.003.

Question 8

Which represents the most critical success factor for implementing anticipatory action at scale in Pakistan?

Technology availability
Developing universal triggers, securing forecast-based financing, building institutional capacity, and integrating with existing preparedness systems✔️
International support
Legal framework

Correct Answer Logic:

Section 7.2 identifies multiple requirements for scaling anticipatory action: developing triggers, securing financing mechanisms, capacity building for implementation, and integration with existing systems. Scaling requires addressing all these systemic elements rather than any single factor.

Passenger and baggage screening
Safeguarding aircraft and airport infrastructure
Regulating civil aviation flight schedules✔️

Sociology QUESTION #1667

Question 10

Pierre Bourdieu's concept of 'habitus' refers to a set of durable, transposable dispositions that shape perception, thought, and action. Which of the following most precisely captures what habitus describes?

The accumulation of culturally valued knowledge and credentials
The networks of social relationships that confer advantage
Internalized, embodied dispositions that are generated by one's social position and structural conditions✔️
The antagonism between competing social classes over economic resources

Correct Answer Logic:

Bourdieu's habitus is a system of durable, transposable dispositions — ways of perceiving, thinking, feeling, and acting — that are acquired through socialization in particular social positions and conditions. It is distinct from cultural capital (knowledge/credentials), social capital (networks), and economic capital (material resources), though all three interact with habitus.

Chemistry QUESTION #4365

Question 11

The theories which explain the formation of sigma ($\sigma$) and pi ($\pi$) bonds are EXCEPT:

MOT
VBT
VSEPR
CFT✔️

Correct Answer Logic:

Valence Bond Theory (VBT) explains $\sigma$ and $\pi$ bond formation through orbital overlap. Molecular Orbital Theory (MOT) also describes bonding. VSEPR predicts shape. Crystal Field Theory (CFT) deals with d-orbital splitting in coordination complexes — it does NOT explain $\sigma$ and $\pi$ bond formation.

Question 13

Evaluate $\displaystyle\lim_{n\to\infty}\left(\dfrac{(n+1)(n+2)\cdots3n}{n^{2n}}\right)^{1/n}$

$\dfrac{27}{e^2}$✔️
$\dfrac{9}{e^2}$
$3\ln3-2$
$\dfrac{18}{e^4}$

Correct Answer Logic:

$\ln L = \lim_{n\to\infty}\dfrac{1}{n}\sum_{r=1}^{2n}\ln\!\left(1+\dfrac{r}{n}\right) = \int_0^2\ln(1+x)\,dx$

$=\left[(1+x)\ln(1+x)-(1+x)\right]_0^2 = (3\ln3-3)-(-1) = 3\ln3-2$

$L = e^{3\ln3-2} = \dfrac{27}{e^2}$

Chemistry QUESTION #1078

Question 15

Statement I: Ferromagnetism is considered as an extreme form of paramagnetism. Statement II: The number of unpaired electrons in Cr$^{2+}$ ion ($Z=24$) is the same as that of Nd$^{3+}$ ion ($Z=60$).

Statement I is true but Statement II is false✔️
Statement I is false but Statement II is true
Both Statement I and Statement II are true
Both Statement I and Statement II are false

Correct Answer Logic:

Statement I is true — ferromagnetism arises from cooperative alignment of magnetic dipoles in domains, and is indeed an extreme form of paramagnetism. Statement II: Cr$^{2+}$ ([Ar]3d$^4$) has 4 unpaired electrons. Nd$^{3+}$ ([Xe]4f$^3$) has 3 unpaired electrons. They are NOT the same. Statement II is false.

Question 17

Natural mechanisms arise whereby every thriving species can _______ its inherent capacity for population growth with the environmental constraints that emerge through its interactions with nature.

enhance
replace
produce
reconcile✔️

Correct Answer Logic:

The sentence describes a balancing act between two opposing forces: innate growth potential and environmental constraints. Reconcile means to bring two opposing things into harmony — the species balances its drive to grow with the limits imposed by its environment. 'Enhance' means to improve one factor, not balance two. 'Replace' and 'produce' don't fit the idea of managing tension between competing forces.

Education QUESTION #6776

Question 19

In a criterion-referenced test (CRT) context, a cut score of 70% is set to distinguish 'master' from 'non-master'. After the exam, 85% of students pass. Which statement about this result is MOST consistent with CRT principles?

This result is anomalous because CRT normally produces a normal distribution of scores
This result is expected and acceptable in CRT; mastery tests are designed with relatively easy items, and it is desirable that most students demonstrate mastery✔️
This outcome shows the test lacked discriminating power and should be revised for better spread
The cut score should be raised to 90% to reduce the pass rate to a more appropriate level

Correct Answer Logic:

In CRT, the test is designed to assess mastery of a defined set of skills; it does not aim to spread students along a distribution. It is entirely acceptable — even ideal — for most students to pass if they have mastered the content. Around 80% correct per item is the expected CRT item difficulty. The purpose is mastery verification, not comparison or ranking.

Question 20

Divide Rs. 4500 among A, B, and C in the ratio $3:4:5$.

A=Rs.900 B=Rs.1200 C=Rs.1500
A=Rs.1000 B=Rs.1500 C=Rs.2000
A=Rs.1125 B=Rs.1500 C=Rs.1875✔️
A=Rs.1200 B=Rs.1500 C=Rs.1800

Correct Answer Logic:

Total parts $= 3 + 4 + 5 = 12$. A $= \dfrac{3}{12} \times 4500 = 1125$, B $= \dfrac{4}{12} \times 4500 = 1500$, C $= \dfrac{5}{12} \times 4500 = 1875$.
