This question was previously asked in
CUET PG 2026 Agri-Business Management Question Paper (25-Mar-2026) (Shift 2)

Evaluating Assertion and Reason Statements

This question requires evaluating two historical statements labeled Assertion (A) and Reason (R) and determining their correctness and relationship.

Analysis of Assertion (A)

Assertion (A) states: The first tractor was developed in the USA in 1910.

  • Historical records indicate significant developments in tractor technology in the USA around the early 20th century. While earlier prototypes existed (e.g., 1892), the period around 1910 saw further advancements and the beginnings of commercialization, making the statement contextually plausible within certain historical frameworks.
  • For the purpose of this question, we accept Assertion (A) as correct.

Analysis of Reason (R)

Reason (R) states: The DDT and BHC insecticides were discovered in 1939.

  • Paul Hermann Müller discovered the insecticidal properties of DDT in 1939, for which he later received the Nobel Prize.
  • Research into BHC (Benzene hexachloride) and its insecticidal uses also gained prominence around the same period, particularly during the 1930s and 1940s.
  • Therefore, Reason (R) is factually correct.

Relationship Between Assertion (A) and Reason (R)

The question asks if Reason (R) is a correct explanation for Assertion (A).

  • Assertion (A) deals with the development of tractors in the USA.
  • Reason (R) deals with the discovery of specific insecticides.
  • These are two independent historical events from different fields (agricultural machinery and chemical pest control).
  • The discovery of insecticides in 1939 has no logical or causal connection to the development of tractors in the USA.
  • Therefore, even though both statements are correct, (R) does not explain (A).

Conclusion

Based on the analysis:

  • Both Assertion (A) and Reason (R) are correct statements.
  • Reason (R) is not the correct explanation of Assertion (A).

This corresponds to Option B.
