Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer : Statements : Wind is an inexhaustible source of energy and an aerogenerator can convert it into electricity. Though not much has been done in this field, the survey shows that there is vast potential for developing wind as alternative source of energy. Conclusions : I. Energy by wind is comparatively newly emerging field. II. The energy crisis can be dealt by exploring more in the field of aero-generation.

The correct answer is: Only conclusion II follows.

The statement says that wind is an inexhaustible source of energy and an aerogenerator can convert it into electricity. The survey shows that there is vast potential for developing wind as alternative source of energy.

Conclusion I: Energy by wind is comparatively newly emerging field.

This conclusion does not follow from the statement. The statement does not say anything about how long wind energy has been used. It is possible that wind energy has been used for centuries, but that the survey shows that there is still vast potential for developing it further.

Conclusion II: The energy crisis can be dealt by exploring more in the field of aero-generation.

This conclusion does follow from the statement. The statement says that wind is an inexhaustible source of energy and that there is vast potential for developing wind as alternative source of energy. This suggests that wind energy could be used to help solve the energy crisis.

The other options are incorrect because they do not follow from the statement.
