问题 PASSAGE THREE
What does the author mean by saying "Its future can now scarcely be in doubt. " in Para. 4?

选项

答案The instrument will definitely be built though expensive.

解析 根据题干定位至第四段最后一句。本段探讨了观测新行星的设备,其中提到观测设备EPICS,这个设备价格昂贵,人们对它是否物有所值存在质疑,而在倒数第二句作者指出,这个设备对于观测新行星有不可替代的优势,有机会拍摄它的照片,分析它的大气,作者接着在最后一句指出,它的未来已经少有疑问了,这显然是说这个设备是会被投资建造的,故答案为“The instrument will definitely be built though expensive.”。
