Set 3: Command of Evidence (Intermediate)

Explanation

Answer: B

PASSAGE

Antibiotic resistance is a growing global health threat. When bacteria are exposed to antibiotics, susceptible ones die, but resistant ones survive and multiply. Over time, a population can become predominantly resistant. The problem is exacerbated by the overuse and misuse of antibiotics in medicine and agriculture.

Which action would most likely reduce the rate of antibiotic resistance development?

A. Prescribing antibiotics for viral infections.
B. Using antibiotics only when medically necessary and completing the full course.✓ Correct
C. Adding antibiotics to all livestock feed.
D. Using the strongest antibiotic first for any infection.

Detailed Explanation

The text says resistance is 'exacerbated by overuse and misuse. ' Using antibiotics 'only when necessary' reduces overuse, and 'completing the full course' prevents partial treatment that allows resistant bacteria to survive.

Key Evidence:

• "overuse and misuse"

Why others are wrong: A (Antibiotics don't work on viruses; this is misuse.), C (This is overuse in agriculture.), D (This could accelerate resistance to the strongest drugs.).
