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.
-
AOnly conclusion I follows
-
BOnly conclusion II follows
-
CEither I or II follows
-
DNeither I nor II follows
-
EBoth I and II follow
Answer
Correct Answer: Both I and II follow
Explanation
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).
Step-by-Step Solution:
From “not much has been done” + “vast potential”: wind energy development is emerging/under-developed (I).From “inexhaustible” + “convertible” + “vast potential”: further exploration can help tackle energy shortages (II).Verification / Alternative check:
If wind were exhausted or not convertible, II would fail; but the passage asserts the opposite. Hence, exploring more is a reasonable remedy.Why Other Options Are Wrong:
A or B alone ignore part of the evidence.C and D contradict the combined implications of feasibility and potential.Common Pitfalls:
Interpreting “deal with the crisis” as “solve entirely.” The exam phrasing typically means “address significantly.”Final Answer:Both I and II follow
