Question 3

Which of these linguistic terms refers to the study of the physical properties and production of speech sounds (the speech process)?

Phonology
Phonetic substances
Phonetics✔️
Semantics

Correct Answer Logic:

Phonetics is the branch of linguistics that studies the physical production, acoustic properties, and perception of speech sounds — the speech process itself. It is divided into: articulatory phonetics (how sounds are produced), acoustic phonetics (sound waves), and auditory phonetics (how sounds are perceived). Phonology studies the abstract sound system and patterns within a language, rather than physical sound production.

Question 5

In which year was the 18th Constitutional Amendment passed by Pakistan's National Assembly?

2009
2010✔️
2011
2012

Correct Answer Logic:

The 18th Constitutional Amendment was passed on April 8, 2010. It was a landmark legislation that significantly decentralized Pakistan, abolishing the Concurrent Legislative List (devolving 47 subjects to provinces), restoring the 1973 Constitution's parliamentary character, renaming NWFP as Khyber Pakhtunkhwa, and curtailing presidential powers. It fundamentally reshaped federal-provincial relations.

Physics QUESTION #1031

Question 6

A particle of mass $m$ moves around the origin under constant force $F$ towards origin. Using Bohr model, how do radius $r$ of $n$th orbit and speed $v$ depend on $n$?

$r \propto n^{2/3};\ v \propto n^{1/3}$✔️
$r \propto n^{4/3};\ v \propto n^{-1/3}$
$r \propto n^{1/3};\ v \propto n^{1/3}$
$r \propto n^{1/3};\ v \propto n^{2/3}$

Correct Answer Logic:

For circular orbit under constant force: $F = \frac{mv^2}{r}\Rightarrow v^2 = \frac{Fr}{m}$. Bohr quantization: $mvr = \frac{nh}{2\pi}\Rightarrow v = \frac{nh}{2\pi mr}$. Substituting: $\frac{F r}{m} = \frac{n^2h^2}{4\pi^2m^2r^2}\Rightarrow r^3 \propto n^2\Rightarrow r \propto n^{2/3}$. Then $v \propto \frac{n}{r} \propto \frac{n}{n^{2/3}} = n^{1/3}$.

Question 7

Thermization (thermalization) of milk involves heating at:

$63^{\circ}\text{C}$ for $30$ minutes
$57\text{–}68^{\circ}\text{C}$ for $15$ seconds✔️
$72^{\circ}\text{C}$ for $15$ seconds
$135^{\circ}\text{C}$ for $2$ seconds

Correct Answer Logic:

Thermization is a mild heat treatment at $57\text{–}68^{\circ}\text{C}$ for $15$ seconds, insufficient to inactivate alkaline phosphatase. It reduces psychrotrophic bacteria counts in raw milk before storage without full pasteurization.

Bio-Technology QUESTION #10595

Question 10

L-Lysine overproduction in C. glutamicum is achieved by deregulating the aspartate pathway. A key mutation required is:

Deletion of the aconitase gene to block the TCA cycle
A feedback-insensitive (desensitised) aspartokinase that is no longer inhibited by lysine + threonine✔️
Overexpression of the glutamate dehydrogenase gene
Introduction of a heterologous arginine biosynthesis pathway

Correct Answer Logic:

In wild-type C. glutamicum, aspartokinase is subject to concerted feedback inhibition by both lysine AND threonine simultaneously. Mutations creating a feedback-insensitive aspartokinase allow carbon flux to continue through the aspartate pathway even when lysine accumulates. Additional engineering includes deletion of competing branches (homoserine dehydrogenase to block threonine synthesis), amplifying lysine-specific enzymes. This rational metabolic engineering produces >100 g/L lysine.

The average of 8 numbers is 25. If each number is multiplied by 4, what is the new average?

25

Question 15

In traffic flow theory, at what density does traffic flow transition from stable to unstable (stop-and-go)?

10-20 vehicles/km/lane
30-40 vehicles/km/lane
50-60 vehicles/km/lane✔️
70-80 vehicles/km/lane

Correct Answer Logic:

The critical density (typically 50-60 vehicles/km/lane depending on conditions) represents the transition from stable flow to unstable stop-and-go traffic. Beyond this density, small disturbances propagate as shockwaves, creating congestion—basis for traffic management strategies.

Question 18

After 3 half-lives, the remaining fraction of a radioactive sample is:

$\dfrac{1}{2}$
$\dfrac{1}{4}$
$\dfrac{1}{8}$✔️
$\dfrac{1}{16}$

Correct Answer Logic:

After each half-life, the remaining fraction is halved. After $n$ half-lives: remaining fraction $= \left(\dfrac{1}{2}\right)^n$. After 3 half-lives: $\left(\dfrac{1}{2}\right)^3 = \dfrac{1}{8}$.

Question 19

In cost-benefit analysis, if Benefit-Cost Ratio (BCR) is 0.85, the project should be:

Immediately approved
Rejected✔️
Modified and reanalyzed
Implemented with subsidies

Correct Answer Logic:

BCR = $\frac{\text{PV of Benefits}}{\text{PV of Costs}}$ < 1.0 indicates costs exceed benefits, making the project economically unviable from a welfare perspective. Projects should only proceed if BCR ≥ 1.0, meaning benefits justify costs.

Civil / Architecture QUESTION #2338

Question 20

In airport terminal design, the distance beyond which assisted passenger movement (travellators, light rail, or buses) is required is:

Over 100 m
Over 200 m
Over 300–400 m✔️
Over 500 m

Correct Answer Logic:

The Architects' Handbook states travel distances of up to 300–400 m are acceptable on foot. Beyond that, assisted movement is required: travellators for 300–1000 m, light rail systems for 1–3 km, and buses for complex multi-stop journeys such as terminal to satellite via the apron.
