You can only be accepted to a university[br]if you are human.Another necessary condition is submitting[br]an application. You can't get accepted to a university [br]unless you apply there.Philosophers sometimes put this by saying[br]that Q is true only if P is true.
Now it's a little harder to think of a [br]sufficient condition for getting accepted to a university.
But consider some seventeen year old who[br]just won the Nobel Prize in chemistry.
"Merely taking the test isn't sufficient [br]for passing it." "The lawyer convinced the jury that there is sufficient evidence to [br]convict the accused." "Pain is a necessary part of every human[br]life." "Practice is really necessary for [br]success." But what exactly do these words mean?
If P is necessary for Q, then Q cannot be[br]true unless P is true.
