but this isnt a little too much time and it is only a few answers. Looking at the scores ( nothing below 70%) It could definitely have less time.
the peole that know them ( or just immediately recognise it) will do it under 20 secs. so 1,5 minute will be fair I guess, leaves you with a minute and 10 seconds to think over a few answers. (anything more than 2 minutes is useles, cause if you havent come up with it in 2 minutes you simply dont know it, it is not like there are 40 questions that you all need to read, whith several suspected answers (was that neutron or proton... etc)
