13. If that insect is a bee, it can only sting once. It only did sting once. So it is a bee.

Which one of the following exhibits a pattern of reasoning most similar to that in the argument above?

(A) Spring is here. It has to be, because when it is spring, I cannot stop sneezing; and I just sneezed.

(B) When the sky is clear, the atmospheric pressure is high. At the moment, it is clearing up, so the atmospheric pressure is bound to be high soon.

(C) Old and brittle paintings are always moved with extreme care. That particular painting is never moved with extreme care. So it must not be old and brittle.

(D) Only one more thunderstorm was needed to ruin that roof. But the roof was still fine a month later. There must not have been any thunderstorm over that month.

(E) To survive in the wild requires physical stamina like Mark’s. All the same, Mark’s fear of spiders would prevent his survival.

答案是A，好心人帮我看看我这样理解A对不对：because when it is spring, I cannot stop sneezing。 and I just sneezed ， so Spring is here。

题干是将必要变为充分，将A的语序改变后（逻辑关系没变），结构与题干类似。

right.提干的逻辑错误是逆命题的错误。A也一样
