I am preparing for HSK 6, and its Reading Part 1, which asks you to identify a 语病 in a sentence, is notoriously hard. Here is one of the sentences from HSK 6 Reading Part 1.
My HSK 6 testbook, which comes without an explanation for each question, says that there is a 语病 in this sentence.
I am guessing that “他的妻子很实惠，又能干又体贴” should be edited to "他的妻子很实惠，能干，体贴." Am I wrong in this?
