About this MCQ
This Medium Science and Inventions MCQ checks one syllabus fact.
The question is: “The process by which green plants use sunlight to convert carbon dioxide and water into food. What is this called?”
The accepted answer is D. Photosynthesis. “The process by which green plants use sunlight to convert carbon dioxide and water into food. What is this called” is answered by Photosynthesis (option D). Option A (“Gravity”) does not match the stem; it is a near-miss used to catch incomplete recall of Photosynthesis. Option B (“Charles Darwin”) does not match the stem; it is a near-miss used to catch incomplete recall of Photosynthesis. Remaining alternatives (Carbon Dioxide) fall outside the same rule and should be eliminated once Photosynthesis is identified. Science and Inventions questions of this type reward precise definitions rather than approximate associations. Science and Inventions recall of this distinction is a regular item in FPSC, PPSC, NTS, and CSS papers.
