what does hesitation mean

Hi,

Hesitation comes from the verb hesitate meaning delay. If you hesitate when you are answering a question for example, you stop/pause for a second before you say something as in: Well, er -um - yes ...'

BTW, I've asked a native english speaker about this sentence and he has told me that "switch" fits here as well, though he hasn't heard this expression before...

My question is whether there are any ambiquous tasks where you can choose 2 or more alternatives or not??

[Alan]

Hi,

We try as much as possible to construct both the sentence and the choice in such a way that there is only one really acceptable word with which to fill the gap. I must admit I have never heard of an expression: as quick as a switch

I can imagine that someone might say "quick as a switch" to descibe a certain kind of movement (for example, the quick, twitching movement of a squirrel's tail). That may well be what lost soul's native speaker meant.

"Quick as a switch" certainly is not a standard, well-known collocation whereas "quick as a flash" is very common and well-known.
