Set T is an infinite sequence of positive integers. A "superset" is a sequence in which there is a finite number of multiples of three. Is T a superset?
(1) The first six integers in T are multiples of three.
(2) An infinite number of integers in T are multiples of four.

Statement 1: The first six integers in T are multiples of three.
There may be more integers in T which are multiples of three and the number of such integers may or may not be finite.

Not Sufficient!!!

Statement 2: An infinite number of integers in T are multiples of four.
This does not tell us anything about the integers which are multiples of three. The number of such integers in T may or may not be finite.

Not Sufficient!!!

1 & 2 Together: Now new information which can allow us to conclude whether the number of integer multiples of three in T are finite or infinite.

Not Sufficient Together!!!

The correct answer is E.
