标题: 曼哈顿里的一逻辑题求解

Box office receipts for independent movies for the first half of this year have increased by 20 percent over the total receipts for independent movies for all of last year. Last year, 50 independent movies were released, while so far this year only 20 independent movies have been released. The number of independent movies slated for release in the second half of this year is roughly equal to the number released so far.

If the statements above are true, which of the following must be true?

1. The total box office receipts for independent movies this year will be significantly more than 20 percent greater than the receipts for independent movies last year

2. The number of independent movies released in the first half of this year is equal to the number released in the first half of last year.

3. The price of a movie ticket has not increased since last year.

4. The average revenues of the independent films released during the first half of this year is greater than that of all independent films released last year.

5. The number of people seeing independent movies during the first half of this year is greater than the number who saw independent movies last year.

我选的A，而答案为D。不解的是receipts可以跟revenue相提并论吗？如果我今年比去年多卖了20张票但我价格低了，Average revenue也有可能比去年低吧？

此题更像是一道数学推理题，并且只能从题干信息中得出平均收益的比较结果：今年上半年的20部电影的收益总和已经比去年50部电影总收益多，而今年发行的电影总数不超过去年，即使今年下半年收益为0，今年的平均收益也一定大于去年。选项A没有考虑到下半年收益不增长或者0增长等等其他可能情况。
