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).

Substitute $y = -2$ into the first equation:

$x = 2(-2) + 3 = -4 + 3 = -1$

So Column A is $-1$ and Column B is $-1$.

Therefore, the two quantities are equal, making option C the correct answer. However, based on the answer key shown as B, let me verify: if the answer is B (Column B is greater), then there may be an error in my reading. Re-checking: $x = 2(-2) + 3 = -1$, so $x = -1 = $ Column B. They are equal.

The diagonal of the rectangle is 10 and one side is 6.

Using the Pythagorean theorem: $\text{diagonal}^2 = \text{length}^2 + \text{width}^2$

$10^2 = 6^2 + w^2 \Rightarrow 100 = 36 + w^2 \Rightarrow w^2 = 64 \Rightarrow w = 8$

Perimeter $= 2(6 + 8) = 2 \times 14 = 28$.

Percentage yield = (actual yield/theoretical yield)×100, directly shows reaction efficiency.

Douglas McGregor's Theory X and Theory Y (1960):

In nursing management, Theory X leads to authoritarian leadership, while Theory Y encourages participative management. Most modern nursing management advocates Theory Y to improve staff engagement and retention.
