Below is given a passage followed by several possible inferences which can be drawn from the facts stated in the passage. You have to examine each inference separately in the context of the passage, decide upon its degree of truth or falsity and choose your answer accordingly from amongst the alternatives provided thereafter. (Q. No. 21 to 23)
Wind is an inexhaustible source of energy and an aerogenerator can convert it into electricity. Though not much has so far been done in this field, the survey shows that there is a vast potential for developing wind as an alternative source of energy. On this basis, U.P.’s hilly areas have been found to be an ideal place for setting up aerogenerators. In U.P. hills alone, as many as 56 sites have been identified.
Energy derived from harnessing wind is a comparatively new and emerging field. (Choose the most appropriate option from below)

Show answer & explanation
Correct answer: A
Concept: In degree-of-truth inference questions, “definitely” requires an explicit statement or an unavoidable logical entailment. “Probably” is used when the stated facts make an inference more likely than not but still leave another explanation possible.
Application: The passage says that little has been done in wind-energy development and that there is vast potential for further development. Those facts support reading the field as early-stage or emerging. However, limited adoption can also occur in an older field, and the passage never states the field’s age directly; therefore newness is supported but not logically forced. The inference is therefore Probably true.
Definitely true requires certainty; the passage does not exclude the possibility of an established but underdeveloped field.
Probably false requires the passage to lean against the inference; limited work and large future potential instead support an early-stage reading.
Definitely false requires an explicit contradiction; the passage gives no statement that wind-energy development is already mature or long-established.
Cross-check: The RSSB Patwar 2025 Shift II final answer key for paper DQ69 confirms that the accepted answer value for question 21 is “Probably true” when matched to the official master paper.
