Chemistry QUESTION #7157

Question 965

The significant reducing ability of hypophosphorous acid ($H_{3}PO_{2}$) is primarily due to the presence of:

Two $P-OH$ bonds
One $P-H$ bond
Two $P-H$ bonds✔️
One $P-OH$ bond

Correct Answer Logic:

The reducing character of oxoacids of phosphorus depends on the number of $P-H$ bonds present. In $H_{3}PO_{2}$ (Hypophosphorous acid), the phosphorus atom is bonded to two hydrogen atoms directly ($2 \times P-H$ bonds) and one hydroxyl group ($1 \times P-OH$ bond). These $P-H$ bonds are responsible for its strong reducing property.

Mathematics QUESTION #1304

Question 967

For $\vec{F}=\left(\dfrac{1}{2}xy^4,\;\dfrac{1}{2}x^4y\right)$, the quantity $\dfrac{\partial Q}{\partial x}-\dfrac{\partial P}{\partial y}$ needed for Green's Theorem equals:

$2x^3y-2xy^3$✔️
$x^3y-xy^3$
$2x^3y+2xy^3$
$x^3y+xy^3$

Correct Answer Logic:

Here $P=\dfrac{1}{2}xy^4$ and $Q=\dfrac{1}{2}x^4y$. $\dfrac{\partial Q}{\partial x}=\dfrac{1}{2}\cdot4x^3y=2x^3y$. $\dfrac{\partial P}{\partial y}=\dfrac{1}{2}\cdot4xy^3=2xy^3$. So $\dfrac{\partial Q}{\partial x}-\dfrac{\partial P}{\partial y}=2x^3y-2xy^3$.

CISA QUESTION #1742

Question 968

Which governance concept captures the idea that the appropriate people of authority examined an issue, exercised sound judgment, and took proportionate and accountable action?

Leadership
Corporate responsibility
Chain of command
Governance✔️

Correct Answer Logic:

Governance, at its most essential, means that decisions are made by individuals who hold the correct level of authority — and that those decisions are both informed and accountable. When critical decisions are made by people who lack the requisite authority, or when decisions are pushed down to inappropriately low levels, it signals a governance failure. Governance is what separates structured, accountable decision-making from organisational anarchy.

The Constitution of Pakistan QUESTION #9359

Question 969

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.

Boilers Mechanical Engineering QUESTION #2387

Question 970

For a type-one system (one integrator in the open-loop transfer function) with a ramp input $X_i(s)=1/s^2$, the steady-state error is:

$E_s = 0$
$E_s = \frac{1}{K_v}$ where $K_v = \lim_{s\to 0} sY_1(s)$ (velocity error constant)✔️
$E_s = \infty$
$E_s = 1$

Correct Answer Logic:

For a ramp input with a type-one system: $E_s=\lim_{s\to 0}\frac{s}{1+Y_1(s)}\cdot\frac{1}{s^2}=\frac{1}{\lim_{s\to 0}sY_1(s)}=\frac{1}{K_v}$. The velocity error constant $K_v=\lim_{s\to0}sY_1(s)$.

Physics and Math QUESTION #768

Question 971

The solution of $1 + \cos x = 0$ is:

$\pi + 2k\pi,\ k \in \mathbb{Z}$✔️
$\pi - 2k\pi$
$2k\pi$
None

Correct Answer Logic:

$1 + \cos x = 0 \Rightarrow \cos x = -1 \Rightarrow x = \pi + 2k\pi,\ k \in \mathbb{Z}$.

Mathematics QUESTION #1283

Question 974

The function $f(x)=e^x$ satisfies the Mean Value Theorem on $[0,1]$. The value of $c\in(0,1)$ guaranteed by MVT satisfies:

e^c = e-1✔️
$e^c=\dfrac{e+1}{2}$
e^c=\dfrac{1}{e}
e^c=1

Correct Answer Logic:

By MVT: $f'(c)=\dfrac{f(1)-f(0)}{1-0}=\dfrac{e-1}{1}=e-1$. Since $f'(x)=e^x$, we get $e^c=e-1$. Since \(1

Administration QUESTION #9563

Question 975

The concept of 'span of control' and 'organizational levels' are inversely related. A government ministry decides to increase the span of control of its Joint Secretaries from 4 to 8 subordinates. What organizational consequence necessarily follows?

The organization becomes taller with more hierarchical levels to maintain effective supervision
The organization becomes flatter with fewer hierarchical levels, reducing communication layers but increasing supervisory load✔️
The organization requires more managers to maintain the same ratio of supervision across all levels
The organization shifts from functional to geographic departmentalization to manage the wider supervisory responsibility

Correct Answer Logic:

Span of control and organizational levels are inversely related: wider span = fewer levels (flatter structure); narrower span = more levels (taller structure). Increasing span from 4 to 8 means each manager supervises more people, reducing the need for additional management tiers — producing a flatter hierarchy with fewer intermediary levels.

Question 976

Under Section 13(1), a civil servant shall retire from service on completing how many years of service qualifying for pension, if directed by the competent authority in the public interest?

Fifteen years
Eighteen years
Twenty years✔️
Twenty-five years

Correct Answer Logic:

Section 13(1)(i) as substituted by Ordinance No. XXXIV of 2001 provides that a civil servant shall retire on such date after completing twenty years of service qualifying for pension or other retirement benefits as the competent authority may, in public interest, direct. In the absence of such direction, retirement occurs at age sixty under clause (ii).

Agronomy QUESTION #2036

Question 977

Physiological maturity in cereal crops is best identified by:

The date 30 days after heading
Formation of the black layer at the base of the grain (in maize) or when grain moisture reaches 30–35% and maximum dry weight is achieved✔️
When the entire crop canopy turns golden yellow
When combine harvester settings indicate optimum grain moisture

Correct Answer Logic:

Physiological maturity marks the cessation of dry matter accumulation in the grain. In maize it is identified by the black layer (abscission layer) at the kernel base. In wheat/rice, grain moisture of 30–35% at maximum dry weight is the indicator — harvesting before this causes yield loss; after causes field losses.
