Ask yourself two questions: Are all of the elements in F also in D? Is there at least one element in D that is not in F? If the answer to both of these questions is "yes", then the statement is true. If the answer to either of the questions is "no", then the statement is false.

Think of the symbol " ⊂ " as talking to you.

" ⊂ " is talking and saying this to you: 

"Every element of the set which is located immediately left of me, is an
element of the set which is located immediately right of me."

All you have to do is decide whether the " ⊂ " is telling the truth or not.
