Question

The fact that at least one species of resistant bacteria has developed for almost every antibiotic is evidence of which condition?
A. The bacteria have adapted and could be evolving into a different species.
B. The bacteria have learned to mimic other species.
C. There is no variation in the bacteria population.
D. The antibiotics are made differently.

Answer 1

Let us take logic into consideration although it is not so obvious.
The answer is A, because they have actually adapted. It is less likely to be B, because they cant mimic other species.
Now of course C and D are out:
reason being is that there must be variations in the bacteria population and antibiotics are never made differently.
