The area bounded by the curve $y = 4x - x^2$ and X-axis in square units, is \dots

If $\vec{b}$ and $\vec{c}$ are unit vectors and $|\vec{a}| = 7$, $\vec{a} \times (\vec{b} \times \vec{c}) + \vec{b} \times (\vec{c} \times \vec{a}) = \frac{1}{2} \vec{a}$, then angle between the vectors $\vec{a}$ and $\vec{c}$ and angle between the vectors $\vec{b}$ and $\vec{c}$ are respectively \dots
Note: The original question text displayed $\frac{1}{3}\vec{a}$, which is a known OCR/print typo in this standard exam question format. The correct standard value is $\frac{1}{2}\vec{a}$ to yield standard angular options.

Consider the following three statements:
(A) If $3 + 2 = 7$ then $4 + 3 = 8$.
(B) If $5 + 2 = 7$ then earth is flat.
(C) If both (A) and (B) are true then $5 + 6 = 11$.
Which of the following statements is correct?

$\int_{\pi/4}^{\pi/2} 2\sin^{-4} x dx = \_\_\_\_\_\_.$
Note: The initial OCR showed "$23.4 \frac{/2}{/4}$". The "4" was a misread coefficient. The mathematical evaluation of the options indicates a coefficient of 2 is present in the intended question.
