13. This summer, Jennifer, who has worked at KVZ Manufacturing for just over three years, plans to spend with her family the entire four weeks of paid vacation to which she is entitled this year. Anyone who has worked at KVZ Manufacturing for between one and four years is automatically entitled to exactly three weeks paid vacation each year but can apply up to half of any vacation time that remains unused at the end of one year to the next year’s vacation.
If the statements above are all true, which one of the following must also be true on the basis of them?
(A) Jennifer did not use two weeks of the paid vacation time to which she was entitled past year.
(B) If Jennifer continues to work for KVZ Manufacturing, she will only be entitled to three weeks paid vacation next year.
(C) The majority of KVZ’s employees use each year all of the paid vacation time to which they are entitled.
(D) Last year Jennifer took only one week of the paid vacation time to which she was entitled.
(E) KVZ Manufacturing sometimes allows extra vacation time to employees who need to spend more time with their families.
我想问的是A也不一定对啊.比如,J请假是前一年的最后一星期和第二年的前3个星期那么不是A就不对了吗?是不是我想多了啊? |
