Difficulty: Medium
About this MCQ
This Medium Science and Inventions MCQ checks one syllabus fact.
The question is: “Select the correct name for: the gas absorbed by plants during photosynthesis and released by humans during respiration.”
The accepted answer is C. Carbon Dioxide. “Select the correct name for: the gas absorbed by plants during photosynthesis and released by humans during respiration.” is answered by Carbon Dioxide (option C). Option A (“Photosynthesis”) does not match the stem; it is a near-miss used to catch incomplete recall of Carbon Dioxide. Option B (“Penicillin”) does not match the stem; it is a near-miss used to catch incomplete recall of Carbon Dioxide. Remaining alternatives (Marie Curie) fall outside the same rule and should be eliminated once Carbon Dioxide 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.
