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. 94 to 96)

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)

  1. A.

    Probably true

  2. B.

    Probably false

  3. C.

    Definitely true

  4. D.

    Definitely false

Attempted by 2 students.

Show answer & explanation

Correct answer: C

Concept: In a statement-and-inference exercise, an inference is judged strictly against what the passage explicitly states, not against outside knowledge. "Definitely true" applies only when the inference is a direct restatement or an unavoidable logical entailment of a fact the passage explicitly states, requiring no extra assumption. "Probably true" applies when the inference is a reasonable, likely extension of the stated facts but is not itself asserted outright. "Probably false" and "Definitely false" apply symmetrically on the negative side, against an inference that runs counter to or contradicts the passage.

Application: The passage explicitly states: "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." This sentence directly asserts that development of wind-energy harnessing is still at an early stage, i.e. that the field is comparatively new and only now emerging as a potential energy source. The inference under test, "Energy derived from harnessing wind is a comparatively new and emerging field," is therefore not an extrapolation beyond the passage; it restates, in different words, exactly what the passage already asserts. No additional assumption is needed to draw it, so the inference is Definitely true.

  • Probably true is not fitting: this label suits an inference that needs an extra assumption beyond the stated facts. Here the passage states the underlying fact directly, so no extra assumption is needed.

  • Probably false is not fitting: this label suits an inference that runs against the general tenor of the passage without outright contradicting it. Here the inference aligns with, rather than opposes, what the passage states.

  • Definitely false is not fitting: this label suits an inference that directly contradicts an explicit fact in the passage. Here the inference matches the explicit fact instead of contradicting it.

Cross-check: This matches the official RSSB Patwar 2025 Shift 2 answer key, which marks Q94 as the option corresponding to Definitely true.
