Explanation:

Question 9

Blood volume is related to body weight; generally, a heavier person has more blood. Option A says heavier people have less blood (incorrect). Option C says lighter people have more blood (incorrect). Option B states the more a person weighs, the more blood they have (correct).

Inhalant drugs can impair cognitive functions. Option A: Inhalants can slow decision - making (correct, as they affect the brain's ability to process information). Option B: Inhalants don't cause drivers to remember to buckle up (illogical). Option C: Inhalants increase, not help with, confusion (incorrect).

At night, color and contrast (which help in seeing objects clearly) are reduced. Visibility (the ability to see) is affected. Speed control is about managing speed, not related to color/contrast. Control (general) is too vague. So the answer is about visibility.

Answer:

B. the more a person weighs, the more blood they have in their body
