Answer 1

Both 1 and 3
Explanation:
(1)

Clearly, all envelopes are rectangular.
(2)

Form the above diagram we cannot conclude that some thin are tiny.
(3) Learned are well read and well read know. So, we can say that Learneds know.
(4) The first statement is talked about 'Dieting' and 'Health' and the second statement is talked about 'Foods' and 'rare' So, there is no relation in these two statements.
