Question

1. as alcohol builds up in your blood, it: slows down your reactions. makes you feel less confident. begins to metabolize itself more quickly. decreases the number of driving errors.

Explanation:

Alcohol is a depressant that affects the central nervous system. As it accumulates in the blood, it slows down neural communication, which in turn slows down physical and mental reactions. Feeling less confident is not a typical direct effect (it might initially cause over - confidence in some due to disinhibition). Alcohol metabolism rate is relatively constant for an individual (about 10 - 15 grams per hour for an average person) and not accelerated by its buildup. And an increase in alcohol in the blood leads to more, not fewer, driving errors due to impaired judgment, vision, and reaction time.

Answer:

Slows down your reactions.
