Question 3

A PAO sanctions expenditure without consulting the Financial Adviser on a matter that falls within the delegated field. The CFAO disagrees with the decision but the PAO overrules him. Which statement BEST describes the legal and procedural position?

The CFAO's objection invalidates the expenditure sanction
The PAO may overrule the CFAO and record reasons but the expenditure within delegated powers remains valid; however the CFAO's advice may not be disregarded for non-delegated matters✔️
Since CFAO works under the PAO the PAO's sanction is always final without any need to record reasons
The CFAO must refer the matter to the Financial Adviser automatically to protect himself

Correct Answer Logic:

The PAOs may exercise delegated powers without consulting the Financial Adviser. The CFAO may however be consulted where considered necessary or advisable. His advice can however be over-ruled by the PAO who may record reasons for overruling the advice. This applies to the delegated field. In the non-delegated field matters must go through proper channels.

Question 4

Which rule of PPRA Rules 2004 explicitly states that any unauthorized breach of these rules shall amount to mis-procurement?

Rule 47
Rule 49
Rule 50✔️
Rule 51

Correct Answer Logic:

Rule 50 contains the specific provision that any unauthorized breach of the PPRA Rules 2004 shall amount to mis-procurement. This rule is concise but carries significant legal weight as it defines the threshold for regulatory violation in the procurement framework.

Mathematics QUESTION #6929

Question 5

Let $I=\displaystyle\int_a^b(x^4-2x^2)\,dx$. Find the ordered pair $(a,b)$ that minimises $I$.

$(0,\sqrt{2})$
$(-\sqrt{2},0)$
$(\sqrt{2},-\sqrt{2})$
$(-\sqrt{2},\sqrt{2})$✔️

Correct Answer Logic:

$x^4-2x^2=x^2(x^2-2)\leq0$ when $|x|\leq\sqrt{2}$ and $\geq0$ outside.

To minimise the integral (make it most negative), integrate over the region where the integrand is most negative — i.e., $[-\sqrt{2},\sqrt{2}]$ where the function is $\leq0$.

Any sub-interval of $[-\sqrt{2},\sqrt{2}]$ gives a more negative (or equal) value, and the widest such interval $[-\sqrt{2},\sqrt{2}]$ gives the minimum.

$(a,b)=(-\sqrt{2},\sqrt{2})$

Urdu QUESTION #4468

Question 9

Translate: کیا وہ بیمار تھا ؟ (Was he sick?)

Is she sick?
Will he be sick?
Was she sick?
None of these✔️

Correct Answer Logic:

The Urdu sentence is masculine ('tha'). Option C uses 'she' (feminine). The correct translation 'Was he sick?' is missing, making 'None of these' the correct choice.

Question 10

Which ONE WORD means: 'A person who cannot read or write'?

Illiterate✔️
Literate
Ignorant
Uneducated

Correct Answer Logic:

'Illiterate' is the precise one-word substitution for a person who is unable to read or write. 'Literate' means the opposite. 'Ignorant' means lacking knowledge generally.

CISA QUESTION #1787

Question 11

What is the most critical issue associated with transferring operational risk to an outsourced contractor?

There is potential for uncontrollable escalation in operating costs over time
Outsourcing transfers the entire risk burden to the contractor
The organization retains legal liability regardless of who performs the work✔️
Outsourcing protects the company from all inherent operational risks

Correct Answer Logic:

While organizations can delegate operational tasks through outsourcing, they cannot transfer legal liability. As demonstrated by global product recall cases, companies remain financially and legally responsible for failures caused by their subcontractors. Liability is an organizational obligation that cannot be outsourced.

Question 12

Change to ACTIVE VOICE: 'A song is being sung by her.'

She sings a song.
She was singing a song.
She is singing a song.✔️
She sang a song.

Correct Answer Logic:

The active voice of 'is being sung' (present continuous passive) is 'is singing' (present continuous active). So 'She is singing a song' is correct.

Chemistry QUESTION #1006

Question 13

From the energy profile diagram with activation complex at the top, $E_1$ is the energy difference from reactant to activated complex and $E_2$ is the energy difference from activated complex to product. Choose the correct option:

Activation energy of both forward and backward reaction is $E_1+E_2$ and reactant is more stable than product.
Activation energy of forward reaction is $E_1+E_2$ and product is less stable than reactant.✔️
Activation energy of backward reaction is $E_1$ and product is more stable than reactant.
Activation energy of forward reaction is $E_1+E_2$ and product is more stable than reactant.

Correct Answer Logic:

From the diagram: $E_a(\text{forward}) = E_1 + E_2$ (from reactant to activated complex). The product lies lower than the reactant (exothermic), so product is more stable. $E_a(\text{backward}) = E_2$ only. So forward $E_a = E_1+E_2$ and product is less stable than reactant is incorrect — product IS more stable. Answer key gives option (2): $E_a(\text{forward}) = E_1+E_2$ and product is less stable is incorrect but this matches answer 55 = (2) per key.

Physics QUESTION #1183

Question 14

The charging and discharging behavior of an ideal RLC circuit is:

Simple harmonic✔️
Linear
Elliptical
Unpredictable

Correct Answer Logic:

In an ideal LC (or lightly damped RLC) circuit, the charge on the capacitor and current in the inductor oscillate sinusoidally — this is simple harmonic oscillation. The differential equation for an LC circuit is $L\frac{d^2q}{dt^2} + \frac{q}{C} = 0$, identical in form to the SHM equation $\ddot{x} + \omega^2 x = 0$.

Psychology QUESTION #9768

Question 15

Specialized cells of the nervous system are primarily responsible for carrying:

Messages
Reflexes
Both messages and reflexes✔️
None of the above

Correct Answer Logic:

Neurons carry both messages (sensory and motor information via electrical impulses) and are involved in reflex arcs. Sensory neurons carry signals to the CNS; motor neurons carry commands to muscles — both functions are integral.

Chemistry QUESTION #7117

Question 16

For an elementary chemical reaction $A_{2} \xrightleftharpoons[k_{-1}]{k_{1}} 2A$, which of the following is the correct mathematical expression for the rate of change of concentration of $A$ ($\frac{d[A]}{dt}$)?

$k_{1}[A_{2}] - k_{-1}[A]^{2}$
$2k_{1}[A_{2}] - k_{-1}[A]^{2}$
$k_{1}[A_{2}] + k_{-1}[A]^{2}$
$2k_{1}[A_{2}] - 2k_{-1}[A]^{2}$✔️

Correct Answer Logic:

The rate of appearance of $A$ from the forward reaction is $2 \times (\text{rate of forward reaction}) = 2k_1[A_2]$. The rate of disappearance of $A$ in the backward reaction is $2 \times (\text{rate of backward reaction}) = 2k_{-1}[A]^2$. Thus, the net rate is $\frac{d[A]}{dt} = 2k_{1}[A_{2}] - 2k_{-1}[A]^{2}$.
