A pupil says a glass had no air as a candle went out. Why the wrong idea?

AFaulty inference drawn
BNo activity was done
CWrong book was read
DA lesson misprint
Answer & Solution
Correct answer: A. Faulty inference drawn
1. In Standard 2 the pupil saw an empty glass put over a burning candle and the candle went out. 2. The activity stayed vivid for two years, but the conclusion drawn was incorrect. 3. So the activity itself was done; the inference from it was faulty. _Source: NCERT Position Paper, National Focus Group on Teaching of Science, Asking questions_
