1.  Statement : Should cutting of trees be banned altogether ?
Arguments :

I. Yes. It is very much necessary to do so to restore ecological balance.
II. No. A total ban would harm timber based industries.
A. If only argument I is strong
B. If only argument II is strong
C. If either I or II is strong
D. If neither I nor II is strong and
E. If both I and II are strong

Answer: Option E

Explanation:

Trees play a vital role in maintaining ecological balance and so must be preserved. So, argument I hold. Also, trees from basic source of timber and a complete ban on cutting of trees would harm timber based industries. So, only a controlled cutting of trees should be allowed and the loss replenished by planting more trees. So, argument II is also valid.
