Would someone who rides in a car with that same person be considered exposed? why or why not?

This completely depends on what they could or could not be exposed to. If you are riding in a car with someone who has a contagious/communicable/infectious disease then there is a high possibility that you could become exposed to that disease. If you are riding in a car with someone who has just had radiation therapy from cancer treatment then yes there is also a possibility that you can become exposed to the radiation too. If you are riding in a car with someone who has an STI then no you will not be exposed.

the answer is:

i had an assignment in the biology course where i should write a few paragraphs about an experience. the teacher didn't give us a rubric. if i had one i could have paid closer attention to the criteria that has the highest scores. this could have improved my grade.

hope it !
