How did intelligence affect uncertainty in the Battle of Midway?

Correct answer: The USA gained an estimate of the Japanese plan reducing the surprise element

Answer: A. Before the Battle of Midway in June 1942, United States naval intelligence obtained important clues about a planned Japanese operation, including the target identified as “AF.” American code-breakers and analysts used intercepted communications and confirmation methods to interpret the plan. This did not remove every uncertainty: commanders still had to estimate timing, forces, and Japanese movements. However, it reduced the danger of complete surprise and helped the U.S. Navy prepare carrier forces near Midway. A is therefore the best answer. B is wrong because it reverses the key intelligence advantage described in this question; Japanese code-breaking did not provide the stated American preparation. C is unrelated to the decisive intelligence issue at Midway. D is also incorrect: Germany did not control the Pacific battle. Memory cue: at Midway, information helped the U.S. prepare an ambush rather than meet an entirely unknown attack.
