TPO25 阅读2 第7题

7.  All of the following are mentioned in paragraph 3 and 4 as contributing to the problems of the Venetian shipbuilding industry at the end of the sixteenth century EXCEPT
○ The quality of work performed in the Arsenale had declined
○ Venetian–built ships were heavy and generally inefficient
○ Arsenale shipbuilders worked more slowly
○ Only a few merchants controlled the buying and selling of most of the Venetian-built ships

这道题我做题的时候想了很久，在AC中纠结。最后选了C。我的理由是文中只是提到造船者的工作时间减少（Older workers had been allowed to stop work a half hour before the regular time），但没有说他们的工作的变慢了。如果一定要说变慢了，那就应该有推断才对。但这是排除题，不能推断的啊。 那C选项为什么是对的呢？
