Question

Which of the following is a bacterial disease that affects the lungs?

A.
pneumonia

B.
emphysema

C.
lung cancer

D.
asthma

Answer 1

The answer is A - pneumonia

Answer 2

A. Pneumonia seems the most likely answer.
Asthma is not bacterial, it is generally inherited so that option can be eliminated. Emphysema is a chronic disease, and lung cancer is caused by toxins in the body. That leaves A. as the only valid option.
