Answer:
B) Prevalence
Explanation:
Prevalence in this case is the number of young women within the age bracket that tested positive for STI this year.
We cannot say this is an epidemic because we don't know if the statistics from the result is normal or higher than what is termed normal. It is also not incidence because incidence has to do with new cases and we were not given enough information to know if it is the first time for those who tested positive or they have tested positive for STI in the past.
Since there are no risk factors involved, we cannot term the data as risk because risk in this case involves the probability of contracting STI.
Well with blocked vessels, lets use plaque buildup as the reason for blocked vessels. It's Like trying to match together two puzzle pieces that don't fit. The piece if forced together, will be a tight fit much like how blood cells/platelets trying to fit through a small area. The pressure will be increase because the more pressure that is being put on will help to push blood through a clotted area.
The answer is experience.
I hope it helped!
