11. If p is a positive odd integer, what is the remainder when p is divided by 4 ? (1) When p is divided by 8, the remainder is 5. (2) p is the sum of the squares of two positive integers. ANS:D 我不知道選項2為什麼對耶 12. Of the 25 cars sold at a certain dealership yesterday, some had automatic transmission and some had antilock brakes. How many of the cars had automatic transmission but not antilock brakes? (1) All of the cars that had antilock brakes also had automatic transmission. (2) 2 of the cars had neither automatic transmission nor antilock brakes. ANS:E 我本來覺得答案是C 我後來我想了一下 覺得: 因為車子不見得只有automatic transmission 和antilock brakes這兩種東西, 所以我知道有2台兩個都沒有時(第二選項), 我不能推出其他的車都有這兩種東西.以致於題目所問的答案是0 是因為這樣,答案才是E的嗎? 謝謝大大們解惑! --
