At work we somehow landed on the topic of how many holes a human has, which then evolved into a heated discussion on the classic question of how many holes does a straw have.
I think it’s two, but some people are convinced that it’s one, which I just don’t understand. What are your thoughts?
It usually does, however, there are cases where a hole can have two openings. For example, there’s a saying/idiom about digging a hole through the earth and ending up in china/australia/etc. It would be confusing to say that you “dug two holes” to China, you would only say that you “dug a hole” to China. “Tunnel” is definitely more precise here, though it would be odd to refer to the openings in a drinking straw as a “tunnel”
