1.  Statement : Wind is an inexhaustible source of energy and an aerogenerator can convert it into electricity. Though not much been does in this field, the survey shows that there is vast potential for developing wind as alternative source of energy.

Conclusions :

I.Energy by wind comparatively newly emerging field.
II. The energy crisis can be dealt exploring more in the field of aero-generation.

A. Only conclusion I follows.
B. Only conclusion II follows.
C. Either I or II follows.
D. Neither I nor II follows.
E. Both I and II follows.

Answer: Option E

Explanation:

The phrase not much has been done in this field'indicates that wind energy is a comparatively newly emerging field.So, I follows. The expression 'there is vast potential for developing wind as thinking changes with the progressing time. So, II does not follow.
