مصدر
فعل
محاورہ
روزمرہ✔️

Correct Answer Logic:

روزمرہ وہ الفاظ، تراکیب یا جملے ہیں جو اہلِ زبان اپنی عام بول چال میں حقیقی یا مستعمل معنوں میں روزانہ استعمال کرتے ہیں۔ محاورہ اس سے مختلف ہے — محاورے میں الفاظ اپنے لغوی معنوں میں نہیں بلکہ مجازی معنوں میں استعمال ہوتے ہیں۔

Question 2

What is the most clinically important advantage of angiotensin II receptor blockers (ARBs) over ACE inhibitors in terms of tolerability?

There is a decreased incidence of hyperkalaemia
They are less likely to cause adverse effects such as dizziness
There is a reduced incidence of cough✔️
They do not interact with non-steroidal anti-inflammatory medications

Correct Answer Logic:

ACE inhibitors cause a dry persistent cough in up to $20\%$ of patients by increasing bradykinin levels. ARBs do not inhibit ACE and therefore have a significantly lower incidence of cough.

A.d 632✔️
A.D. 633
A.D. 634

Question 6

OPPROBRIOUS: Choose the word most nearly opposite in meaning to this word.

meretricious
innocuous
invulnerable
irreproachable✔️

Correct Answer Logic:

OPPROBRIOUS means expressing harsh criticism or disgrace — bringing shame. Its antonym is irreproachable, meaning beyond criticism or blame — completely faultless. 'Meretricious' means falsely attractive. 'Innocuous' means harmless. 'Invulnerable' means cannot be harmed. 'Irreproachable' is the strongest antonym as it means deserving no reproach whatsoever.

Question 7

The steady-state error for a unit step input applied to a type-zero closed-loop system (with unity feedback) is:

$E_s = 0$
$E_s = \frac{1}{1+K_p}$ where $K_p = \lim_{s\to 0} Y_1(s)$✔️
$E_s = 1$
$E_s = \infty$

Correct Answer Logic:

For a type-zero system with unit step input: $E_s=\frac{1}{1+Y_1(0)}=\frac{1}{1+K_p}$ where $K_p$ is the position error constant. For a type-one system (pole at origin), $E_s=0$ for a step input.

Physics QUESTION #7077

Question 10

A damped oscillator's amplitude reduces to $0.9$ times its starting value over $5$ seconds. Determine the factor $a$ by which the amplitude will have decreased relative to the original magnitude after an additional $10$ seconds.

$0.7$
$0.81$
$0.729$✔️
$0.6$

Correct Answer Logic:

In damping, the amplitude follows $A = A_0 e^{-\gamma t}$. In $5\text{s}$, $A_1 = 0.9 A_0$. After a total of $15\text{s}$ ($5\text{s} + 10\text{s}$), the time is three times the initial interval. Thus, the amplitude becomes $A_2 = A_0 (0.9)^3 = 0.729 A_0$. The factor $a$ is $0.729$.

Question 11

According to Maslow, can a person lacking a job, friends, and a home still achieve self-actualization?

100% yes
100% No✔️
None of these
It depends

Correct Answer Logic:

According to Maslow's hierarchy of needs, self-actualization can only be reached after lower needs (physiological, safety, belonging, esteem) are met. A person lacking job, friends, and home has unmet basic needs, making self-actualization impossible under his model.

The Constitution of Pakistan QUESTION #9361

Question 14

Article 175E grants the Federal Constitutional Court exclusive original jurisdiction over disputes between Governments. The court's remedy in such cases is limited to:

Any appropriate remedy including injunctions
Declaratory judgments only✔️
Damages and compensation
Criminal sanctions against responsible officials

Correct Answer Logic:

Article 175E(2) explicitly provides that 'in the exercise of the jurisdiction conferred on it by clause (1), the Federal Constitutional Court shall pronounce declaratory judgments only.' This restricts the FCC's inter-governmental dispute remedy to declarations rather than coercive orders.

Question 15

In Ibsen's A Doll's House, Mrs. Linde serves as a foil and model to __________, who recognises through her that a woman is entitled to her own judgment and independent thought.

Gina
Rebecca
Nora✔️
Hedda

Correct Answer Logic:

In Ibsen's A Doll's House, Nora Helmer is the central protagonist. Mrs. Linde (Kristine) serves as her foil — a contrast and model. While Nora has lived a sheltered, dependent life, Kristine Linde has experienced financial hardship, independence, and self-reliance. Through her friendship with Kristine, Nora comes to recognise her own capacity for independent thought and ultimately leaves her husband.

Question 16

The Froude number $Fr$ is the ratio of inertial forces to gravity forces, expressed as:

$Fr = V / \sqrt{gL}$ — ratio of flow velocity to wave speed✔️
$Fr = \rho V^2 / (gL)$
$Fr = V \sqrt{L/g}$
$Fr = \sqrt{gL}/V$

Correct Answer Logic:

Froude number: $Fr=V/\sqrt{gL}$. When $Fr<1$: subcritical flow; $Fr>1$: supercritical flow; $Fr=1$: critical flow.

Constitutional Law QUESTION #5812

Question 17

The President enters into an executive agreement with a foreign nation to allow for the mutual exchange of criminal records for counter-terrorism purposes. A federal statute, however, expressly prohibits the disclosure of such records to foreign entities without a court order. Which prevails?

The executive agreement, because the President has plenary power over foreign affairs.
The executive agreement, because it was entered into after the statute was enacted.
The federal statute, because an executive agreement cannot override an existing act of Congress.✔️
The federal statute, because criminal records are a matter of domestic privacy law.

Correct Answer Logic:

Executive agreements (unlike ratified treaties) do not prevail over prior conflicting federal statutes. Under the Youngstown framework, when the President acts in opposition to the expressed will of Congress, his power is at its 'lowest ebb.'

Question 18

In DNA, the amount of adenine equals the amount of thymine, and the amount of guanine equals the amount of cytosine. This is known as:

Watson-Crick pairing
Chargaff's rules✔️
Central dogma
Semiconservative replication

Correct Answer Logic:

Chargaff's rules state that in DNA, the molar ratio of adenine equals thymine ($A = T$) and guanine equals cytosine ($G = C$). This reflects the complementary base pairing in the double helix.

Mathematics QUESTION #966

Question 19

If $A$ and $B$ are two events such that $P(A \cap B) = 0.1$, and $P(A|B)$ and $P(B|A)$ are the roots of the equation $12x^2 - 7x + 1 = 0$, then the value of $\dfrac{P(\overline{A} \cup \overline{B})}{P(\overline{A} \cap \overline{B})}$ is:

$\dfrac{4}{3}$
$\dfrac{7}{4}$
$\dfrac{5}{3}$
$\dfrac{9}{4}$✔️

Correct Answer Logic:

Roots of $12x^2-7x+1=0$ are $\frac{1}{3}$ and $\frac{1}{4}$. Since $P(A|B)=\frac{P(A\cap B)}{P(B)}=\frac{1}{3}$ gives $P(B)=0.3$, and $P(B|A)=\frac{1}{4}$ gives $P(A)=0.4$. Then $P(A\cup B)=0.6$, $P(\overline{A}\cup\overline{B})=1-0.1=0.9$, $P(\overline{A}\cap\overline{B})=0.4$. Ratio $=\frac{0.9}{0.4}=\frac{9}{4}$.

Question 20

Effect of increased substrate concentration on enzyme activity:

Decrease the rate of reaction
Increase the reaction rate until all active sites are saturated✔️
Have no effect on the reaction rate
Increase the rate of reaction in a straight diagonal line

Correct Answer Logic:

As substrate concentration increases, more enzyme active sites are occupied and reaction rate increases. However, once all active sites are saturated ($V_{max}$), the rate plateaus.
