Analyze and comment on the following sentences based on the concept that antonyms differin semantic inclusion.
［A］ How tall is his sister?
［B］ How short is his sister?
【正确答案】：Sentence [A] includes the meaning of[B].
The use of tall does not exclude the possibility of his sister being very short.
Sentence [B] is much more restricted in sense and is considered semantically abnormal unless the speaker is particularly interested in the shortness of his sister or curious enough to find out how short his sister is.
