1.TO LET YOU GET THROUGH

2.i 。。12点钟的表 不就是时针分真重合么 不就是i么。。

3impossible。也就是不可能出现这种情况。--个人观点。

4找规律！！ 30， 31， 30，和什么最有可能有联系，月份的天数；再看看字母，正好是 Sept. Oct. Nov.的首字母.答案是Dec.31即 D31

3.The answer to the extra credit problem is: 44

In general,, one can see that the hands would form a right angle twice per hour (at quarter to and quarter past the hour), and then with 24 hours/day = 48. But not so fast. There's an oddity in there. Between 2:00 and 3:00 and then again between 3:00 and 4:00, only 1 right angle is formed. (draw it out for yourself to see this - makes for a nice holiday brain teaser for the neices and nephews). So you have to subtract 4 from the count (to cover both am and pm) to get 44.
