(单选题)

How do researchers use the artificial “tongue” to tasting subtle differences between whiskies? ( )

A.taste buds.
B. By identifying chemicals.

B.By the ‘taste’ of each sample.

C.By the way to absorb light when submerged.

参考答案：C

参考解析：

根据第6段make a single artificial tongue that uses two different types of nanoscale metal ‘taste buds’ which provides more information about the ‘taste’ of each sample可知智能舌头使用不同型号的金属纳米材料制作的味蕾来品鉴样品，而选项A表述并不符合对智能舌头的表述，此味蕾非彼味蕾，只是功能与人的味蕾相似而已，A项表述不准确，选项C表述更合适；根据第5段it can’t identify the individual chemicals…可知智能舌头并不能辨别化学物质，选项B表述错误；根据第9段researchers then measured how they absorbed light while submerged.可知光线的混合是由研究者操作，并非智能舌头，所以选项D表述有误。故本题正确答案选C。
