When reading sheet music for piano.... If the time signature is 4 over 4 and there are two semi quaver rests one above the other do you add them and rest for a crotchet and if so why don't they just put a crotchet rest symbol as opposed to two semi quaver rests?

if so what kind?

There are 9 balls each weighs exactly the same except one. It is either heavier or lighter you don't know. you have a balance scale and are allowed two chances to weigh the balls to find the ball which is either heavier or lighter. you can wiegh and split the balls as you wish.

how do you do find it?

Why is it that women can't let one guy go until they have another? like monkeys can't let one branch go before they hold another? Scared to fall?

Three guys in a room (no mirrors) each wearing a hat. None of them can see their own hat or take it off and look at it. The only form of communication is to raise a hand when you see a red hat. they are told their hats can either be black or red.

It just so happens all the hats are red. If they figure out the colour of their hat they can leave the room.

After ten minutes one guy leaves the room. How did he figure out the colour of his hat?
