Read the passage: "Antibiotic resistance grows when antibiotics are prescribed for viral infections, which they cannot cure." It can be inferred that
- A. viruses are unaffected by antibiotics
- B. all bacteria are now resistant
- C. doctors never prescribe correctly
- D. antibiotics cure most viral illnesses
Explanation
The clause which they cannot cure states directly that antibiotics do not work against viruses, so the inference is close to the text. The other options overstate what is written, and a valid inference must follow from the passage rather than extend beyond it. Watch for absolute words such as all and never in wrong options.
