单选题 What's the purpose of this passage?

A、 To introduce the main purpose of the project to the readers
B、 To express the author's opposition to the project
C、 To appeal to the public to fight against the project
D、 To inform the readers of the controversy over the project

【正确答案】 B

【答案解析】作者虽然一开始介绍了这个项目的情况，但只是引入主题，紧接着作者就说“Yet from the day the research program was launched at the start of the year, it has been the target of intense suspicion, from both right and left.”主要就开始谈各方对此的反对理由。从文章大篇幅论述其缺陷可以很明显地看出作者对此项计划的态度，即持反对态度。
