An insect has been trapped in my side table for almost two years. It makes "grinding" noises occasionally, but how is it surviving without water?
An insect has been trapped in my side table for almost two years. It makes "grinding" noises occasionally, but how is it surviving without water?There’s a good chance that this is the ‘death watch beetle’, Xestobium rufovillosum. Their larvae may survive for years in hardwoods, and the adults are well known to make noises that creep out people.See: Death Watch Beetle - Xestobium rufovillosum - Overview - Encyclopedia of Life
A farmer has five haystacks in one field and four haystacks in another. How many haystacks would he have if he combined them all in one field?
This depends entirely on how one disambiguates the word “combined.” If you mean that it was the haystacks that were combined, then the people who answered “one big haystack” are correct. If, on the other hand, you mean that the fields were combined (say by removing the fence between them) then the people say “there would still be nine” are correct.It's like the old question about a tree that falls in the forest with no person around. Does it make a noise? That depends entirely on your definition of a noise. If you define a sound as moving air, then it makes a noise. If you define a noise as moving air that strikes a human ear, then it doesn't.It's semantics.
