With reference to the above passage, the following assumptions have been made :
1. A study of the famous battles of history would help us understand the modern warfare.
2. Studying the history is essential for anyone who aspires to be a leader.

Which of these assumptions is/are valid?

Correct Option: Neither 1 nor 2

The passage asserts that a working knowledge of ancient history is helpful for interpreting current events. It further suggests that studying famous historical battles is highly beneficial for those who lead or aspire to lead, as it reveals the leadership qualities of winners and the deficiencies of losers, reflecting a recurring pattern throughout the centuries. Assumption 1 is invalid because the passage mentions studying "famous battles of history" to extract leadership lessons, not specifically to understand "modern warfare". This is an over-extrapolation of the text. Assumption 2 is invalid because while the passage recommends studying history to leaders or aspiring leaders for its valuable lessons, it does not state that studying history is "essential" (an absolute necessity) for "anyone" who wants to be a leader. Such extreme assumptions are logically incorrect. Therefore, neither assumption 1 nor 2 is valid, making option D the correct answer.
