All doctors in the hospital attended the seminar. Dr Ahsan did not attend the seminar. Which conclusion follows?
Correct answer: A. Dr Ahsan is not a doctor in that hospital
- A. Dr Ahsan is not a doctor in that hospital
- B. Dr Ahsan was ill
- C. The seminar was not important
- D. Dr Ahsan is a doctor elsewhere
Explanation
If every doctor in the hospital attended, then anyone who did not attend cannot be a doctor in that hospital, which is a valid contrapositive. The other options add information the statements never supply, such as a reason for the absence. A conclusion must follow necessarily, not merely plausibly.

About Critical Thinking
Critical thinking examines how conclusions follow from evidence, including claims, assumptions, arguments, inferences and relevant facts. Questions ask you to identify hidden assumptions, distinguish strong from weak evidence, assess cause and effect, recognise common reasoning errors, and decide which statement strengthens or weakens an argument.
