FIA Assistant Director Paper 2019 Batch 1

Option A correctly uses past tense consistently and the phrase 'he thought his eyes will water' is better expressed as 'he thought his eyes would water' to maintain past tense consistency. However, option A is closest and grammatically correct compared to others. Option C has a grammatical error ('the thought' should be 'thought').

The moment (torque) about point P is calculated by the cross product of the position vector r (from P to Q) and the force vector F. Here, r = i + j + k and F = 2i - j - k. The cross product r × F = (i + j + k) × (2i - j - k) = 3j - 3k, which corresponds to option C.

Section 7-B of the FIA Act specifically provides for the delegation of powers to officers and employees of the FIA. Therefore, option B is correct, not C.

Ashraf Ghani officially took office as the President of Afghanistan on 29 September 2014, which is widely recognized as the formal start of his presidency. While some sources mention a formal inauguration ceremony, the key date marking the beginning of his presidency is 29 September 2014, not October 2014. Therefore, option A (September 2014) is the correct answer.

If a square matrix A satisfies A² = 0 (the zero matrix), it means A is nilpotent and cannot be invertible. Therefore, A is singular because only invertible matrices are called regular (non-singular).

The Simon Commission, formally known as the Indian Statutory Commission, was appointed by the British government in November 1927 to review the political situation and constitutional reforms in British India. It arrived in India in early 1928. The options given (1925, 1926, 1927, None of these) do not include the exact appointment year 1927 as a standalone correct choice because the commission was appointed specifically in November 1927, which is late in the year, and the arrival and activity mainly took place in 1928. Therefore, the best answer among the given options is 'None of these' since the commission was appointed in late 1927 and arrived in 1928, not exactly in 1925, 1926, or early 1927.
