Question

One should not sleep under a tree at night because

• A. Release of less oxygen
• B. Release of carbon dioxide
• C. Release of carbon monoxide
• D. Release of more oxygen

Answer 1

The correct option is B

Release of carbon dioxide

One should not sleep under a tree at night because during night time plants take in oxygen and release carbon dioxide. So the amount of carbon dioxide in the air becomes more which leads to respiratory problems.
