Answer: A
Both (A) and (R) are true and (R) is the correct explanation of (A). After the Corn Laws were scrapped, food could be imported more cheaply, making British domestic agriculture uncompetitive, which led to vast lands being left uncultivated and thousands losing agricultural jobs.
The passage from section 2.1 directly states: "After the Corn Laws were scrapped, food could be imported into Britain more cheaply than it could be produced within the country. Vast areas of land were now left uncultivated, and thousands of men and women were thrown out of work." This confirms both the Assertion and the Reason, and shows the Reason is the direct cause of the Assertion — making Option A correct. Remember: for Option A, the Reason must not just be true but must logically explain why the Assertion occurred.
