Question
Consider the following statements:
Statement 1: All scholars are microbiologists.
Statement 2: Some microbiologists are scientists.
Conclusions:
a. All scholars are scientists.
b. Some scholars are scientists.
c. Some scientists are microbiologists.
d. Some microbiologists are scholars.
Which of the conclusions logically follow from the above statements?
- A. All of the four
- B. c and d only (Correct answer)
- C. c only
- D. None of the four
Correct Answer
Option B — c and d only
Detailed Solution & Explanation
The correct answer is c and d only.
Key Points
- *All scholars are microbiologists* converts to some microbiologists are scholars — conclusion d follows.
- *Some microbiologists are scientists* converts symmetrically to some scientists are microbiologists — conclusion c follows.
- So exactly c and d follow.
Additional Information
- Conclusion a (*all scholars are scientists*) fails: only *some* microbiologists are scientists, and the scholars need not fall among them.
- Conclusion b (*some scholars are scientists*) fails for the same reason — the middle term *microbiologists* is undistributed, so no link between scholars and scientists is established.
- A particular premise (*some…*) can never yield a universal conclusion, and two premises cannot establish a connection unless the middle term is distributed at least once.
