Consider the two statements: 

I:	Retroviruses are useful as vectors in gene therapy.
II:	They can produce useful gene products in significantly greater quantities than a single human cell can.

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. Only I is correct.
4. Both I and II are incorrect.
