Question

A doctor suspects you might have a certain strain of flu and wants to test your blood for the presence of markers for this strain of virus. Why would it be good for the doctor to take a sample of your blood rather than use the population? A.Testing all of the people in my city would be expensive and take too much time B.Testing all of the people in the hospital wouldn't tell them about my specific condition C.Testing all the blood in my body isn't really possible while keeping me alive

Answer 1

B. Testing all of the people in the hospital wouldn't tell them about my specific condition

Step-by-step explanation: As explained in the answer, the doctor suspects that you have a specific strain of flu, so it is not useful to test others because the suspected patient is already near. Also, you may be the first carrier of this strain of flu so the doctor would maybe want to focus on any changes found daily.

Answer 2

A, B, and C. all of them are reasonable choices and wouldn’t give any conclusion, because not everyone has the flu
