Mathematics QUESTION #4145

Question 4364

Solve $\frac{dy}{\sqrt{1-y^2}} = \frac{dx}{\sqrt{1-x^2}}$ with $y(0) = \frac{\sqrt{3}}{2}$. What is the solution?

$\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{3}$
$\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{6}$
$y = \sin(\sin^{-1}(x) + \frac{\pi}{3})$
Both (A) and (C)✔️

Correct Answer Logic:

Integrating: $\sin^{-1}(y) = \sin^{-1}(x) + C$. At $x=0$, $y=\frac{\sqrt{3}}{2}$: $\frac{\pi}{3} = 0 + C$, so $C = \frac{\pi}{3}$. Thus $\sin^{-1}(y) = \sin^{-1}(x) + \frac{\pi}{3}$, equivalent to $y = \sin(\sin^{-1}(x) + \frac{\pi}{3})$.

CISA QUESTION #1790

Question 4368

According to ISACA, which description best defines a 'strong control'?

Effective deployment of multiple overlapping controls aimed at the same objective✔️
A preventive control that completely stops a problem from ever occurring
Implementing at least one control each from the detective, corrective, and preventive categories
Applying comprehensive pervasive controls within an ERP application

Correct Answer Logic:

A strong control uses multiple layers — combining administrative, physical, and technical methods across detective, corrective, and preventive categories. This layered approach, known as depth of control, ideally spans all nine control layers. Relying on a single control type represents a weak control posture.

Verbal Reasoning QUESTION #8178

Question 4369

Given the equation $\dfrac{1-x}{x-1} = \dfrac{1}{x}$, compare:

Quantity A: $x$

Quantity B: $-\dfrac{1}{2}$

Quantity A is greater
Quantity B is greater✔️
The two quantities are equal
The relationship cannot be determined from the information given

Correct Answer Logic:

Simplify $\dfrac{1-x}{x-1}$: note that $1 - x = -(x-1)$, so $\dfrac{1-x}{x-1} = -1$ (for $x \neq 1$).

The equation becomes: $-1 = \dfrac{1}{x}$

$x = -1$

Quantity A $= -1$. Quantity B $= -\dfrac{1}{2}$.

Since $-1 < -\dfrac{1}{2}$, Quantity B is greater.

Administration QUESTION #9550

Question 4372

Pakistan's 1973 Administrative Reforms merged all civil service classes into a unified graded structure. Which specific structural problem — identified by the Egger Report (1953) and Gladieux Report (1955) — was this reform primarily designed to correct?

Excessive delegation of authority to provincial civil servants at the expense of federal control
The dominance of generalist cadres (CSP) over technical and specialist services, creating inequity and inefficiency✔️
The lack of training institutions for pre-service and mid-career civil servants across occupational groups
The absence of a competitive examination system for entry to managerial positions in the federal civil service

Correct Answer Logic:

Both Egger and Gladieux independently criticized the superiority of the generalist CSP over technical and specialist services. The 1972 Administrative Reforms Committee and subsequent 1973 reforms addressed this by merging all services into a unified graded structure (Grades 1–22), creating 'Occupational Groups' with equal pay scales and promotion prospects, and eliminating the institutionalized dominance of one cadre.

Journalism / Mass Communication QUESTION #6366

Question 4377

The first Indian sound film, Alam Ara (1931), directed by Ardeshir Irani, was significant for multiple reasons. Which of the following is the MOST historically accurate statement about this film?

It was the first film shot in colour in the Indian subcontinent
It was the first Indian film with a soundtrack, released on March 14, 1931, and contained seven songs✔️
It was the first film produced in Pakistan after independence
It was the first silent film produced in the subcontinent

Correct Answer Logic:

Alam Ara (1931), directed by Ardeshir Irani for Imperial Film Company, holds the distinction of being India's first talkie film (a film with a recorded sound track). It was released on 14 March 1931 at Bombay's Majestic Cinema. The film was 10,500 feet long, ran for seven weeks, contained seven songs, and was a romantic costume drama. Its success proved that there was a huge market for “talkies and musicals,” and the entire film industry quickly switched to sound production. Note: Ardeshir Irani also directed Kisan Kanya (1937), which was the first colour film (Option A is therefore incorrect). The first silent feature film of the subcontinent was Raja Harishchandra (1913) by Dadasaheb Phalke. The first Pakistani film after independence was Teri Yaad (1948).
