After the math contest, Xiaoming and Obana Xiao Qiang each won a medal. One of them won the gold medal, one won the silver medal and one won the bronze medal. Teacher Wang guessed: "Xiaoming won the gold medal;" Xiaohua may not win the gold medal; Xiao Qiang can't win the bronze medal. " As a result, Mr. Wang only guessed one. Then Xiaoming got the first _ _ _, Xiaohua got the first _ _, and Xiao Qiang got the first _ _ _.

Logical reasoning answer:

Logic problems usually adopt correct reasoning directly, analyze them one by one, discuss all possible situations, abandon unreasonable situations, and finally get the answer to the question. Here is an analysis of the medals won by Xiao Ming.

Solution: ① If "Xiao Ming won the gold medal", Xiaohua must have "failed to win the gold medal", which is inconsistent with "Mr. Wang only guessed one" and irrelevant.

(2) If Xiaoming wins the silver medal, we will discuss it separately according to Xiaohua's winning situation. If Xiaohua won the gold medal and Xiao Qiang won the bronze medal, then Mr. Wang didn't guess one, which is irrelevant. If Xiaohua wins the bronze medal and Xiao Qiang wins the gold medal, it doesn't matter if Mr. Wang guessed two correctly.

(3) If Xiaoming wins the bronze medal, it will be discussed separately according to Xiaohua's winning situation. If Xiaohua wins the gold medal and Xiao Qiang wins the silver medal, then Mr. Wang only guesses Xiao Qiang's medal ranking, which is in line with the question. If Xiaohua won the silver medal and Xiao Qiang won the gold medal, then Miss Wang guessed two correctly, which is irrelevant.

To sum up, Xiaoming, Xiaohua and Xiao Qiang won the bronze medal, gold medal and silver medal respectively, which is in line with the meaning of the question.
