Question

Which of these options which when inserted at [8], would be the most relevant addition to the paragraph?

• A. Very few people in the developed world suffer from diseases of nutritional deficiency, however
• B. New varieties of corn and rice have been developed to resist drought and heat, which will make them useful in dry countries near the Equator in Africa
• C. "Golden rice" has been engineered so that its grains contain vitamin A, as necessary nutrient that many people in Africa and South Asia lack in their diets
• D. Many farmers in the developing world are subsistence farmers, who grow only enough food for themselves and their families

Answer 1

The correct option is C "Golden rice" has been engineered so that its grains contain vitamin A, as necessary nutrient that many people in Africa and South Asia lack in their diets

The sentence prior to [8] mentions about GM crops with enhanced nutritional values which can be used in developing countries. Hence option C which includes the same point is the most relevant addition to the paragraph at that point.
Hence option C is correct.
Option A is also close to the same topic but ends abruptly with the word 'however'. So, option A is incorrect.
Option B is incorrect as it talks about crops that can with stand natural conditions, so it is incorrect.
Option D says that there is no issues in the developing countries and this is not correct information, so option D is incorrect.
