Select a topic sentence that doesn't make sense given the thesis that the most difficult aspect of war to prepare for is friction.

The selection of the statement regarding the ease of replicating friction through military drills aligns well with the thesis that friction is the most difficult aspect of war to prepare for. Friction typically refers to the unpredictable chaos and complications that arise in warfare, which can stem from numerous sources including the behavior of adversaries, environmental conditions, and the interplay of differing forces during conflict.

When the assertion is made that friction can be easily replicated through military drills, it contradicts the thesis by suggesting that such complexities are manageable or straightforward to simulate. The nature of friction in actual war scenarios is often chaotic and unpredictable, making it a significant challenge to prepare for in training exercises. This is fundamentally at odds with the idea that preparation for such friction is difficult and requires a more nuanced understanding of real-world conditions.

The other statements provide valid insights into different facets of friction and its implications in warfare, remaining consistent with the overarching thesis by exploring the challenges and uncertainties inherent in preparing for war.
