In North America there has been an explosion of public interest in, and enjoyment of, opera over the last 3 decades. The evidence of this explosion is that of the 70 or os professional opera companies currently active in North America, 45 were founded over the course of the last 30 years.

The reasoning above assumes which of of the following?

b) there were fewer than 45 professional opera companies that had been active 30 years ago and that ceased operations during the last 30 years.

e) the 45 most recently founded opera companies were all established as a result of enthusiasm on the part of a potential audience.

*which one is the answer and why?

我笨，我努力

b

我一般看到fewer我都想成more

assumption题；原题干取非：有更多的这样的公司；30年前就积极于戏剧事业但中途放弃了。

言外之意，放弃的比新增加的更多，削弱原文，为正确答案

同意B。

E的错误：E指出45家公司新成立的原因，但对这个原因取非并不能削弱原文的结论。
