B) {x|x ∈ U and 2x is prime}
x is greater than 1.
the only even prime number is 2
2 times anything is even.

every value 2x will have a multiple of 2 so it will not be prime.
My favorite way is to hold down Ctrl, Alt, and Delete all at once. This will open up a screen on you computer where you can select Task Manager.
