Question

Statement I: Policemen regulating traffic at a crowded crossing often wear a mask.

Statement II: Mask filters carbon dioxide and sends pure oxygen inside.

• A. Both statements are true
• B. Both statements are false
• C. Statement I is true and statement II is false
• D. Statement I is false and statement II is true.

Answer 1

The correct option is C

Statement I is true and statement II is false

The air at a crowded crossing is generally very polluted. The mask over policemen's nose filters dust from the air but it is not meant to filter carbon dioxide.
