Correct answer: A. Attack on opposing ideas and knowledge
Explanation: The direct answer is A: attack on opposing ideas and knowledge. In the Nazi worldview, the state tried to control what people read, learned, and believed. Books written by Jewish, communist, liberal, pacifist, or other disliked writers were attacked or burned. The reasoning is: a dictatorship fears independent thinking; independent books spread different ideas; therefore burning books symbolised censorship, cultural control, and the destruction of dissent. Option A is correct because it directly describes this attack on knowledge and disagreement. Option B is wrong because burning books destroys access to learning rather than expanding libraries. Option C is wrong because scientific debate needs openness and evidence, while Nazism suppressed unwanted views. Option D is wrong because book burning has no meaning of increasing the education budget. Remember: when a regime burns books, it is trying to burn ideas, not improve education.
