When faced with a friend who is trying to drive under the influence: ✗ a. make sure a sober driver follows your friend home ✗ b. it's always safe with a bac under .08% ✗ c. both a and b ✗ d. neither a nor b?

I believe the answer is: d. neither a nor b

Your sober friend would had the better reflex and judgement, so he/she should be the one that is driving the drunk friend, not just folllowing them. Every individuals had different alcohol tolerance, so even if your bac is still under .08 %, there is no guarantee that your response time hasn't been compromised.

is this even a question? ? : /

answer; the population in brazil is very diverse there are many races and ethnic groups
