In the past, the answers to the college entrance examination papers were regular. If 80% of them are positive, then the probability that the rest of them will not be fooled is also high. Math options are usually 4, 4, 4, 4 or 3, 5, 5, 3, and English cloze is usually 5, 5, 5, 5 or 4, 6, 6, 4. Of course, not necessarily in this order, if there are only two or three questions. But this was several years ago, for reference only. Strength is the most important thing.
