Argument Evaluation – Alternative energy from wind 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, a survey shows vast potential for developing wind as an alternative source of energy. Conclusions: I. Energy by wind is a comparatively newly emerging field. II. The energy crisis can be dealt with by exploring more in the field of aero-generation.

Introduction / Context:
The passage claims wind is inexhaustible, convertible via aerogenerators, and presently under-developed despite “vast potential.” We must see which conclusions logically follow from these claims in the context of typical reasoning questions about alternative energy.

Given Data / Assumptions:

• Wind energy exists in abundance and is renewable.
• Aerogenerators can convert wind into usable electricity.
• “Not much has been done” but “vast potential” exists.

Concept / Approach:
If little work has been done and potential is large, the field is comparatively new or under-tapped—supporting Conclusion I. If potential is vast and conversion is feasible, exploring this field is a viable response to energy shortages—supporting Conclusion II (in the sense of significantly helping to address the crisis).
