Statements: All engineers are graduates. Some graduates are unemployed. Which conclusion follows?
Correct answer: C. No definite conclusion about engineers follows
- A. Some engineers are unemployed
- B. No engineer is unemployed
- C. No definite conclusion about engineers follows
- D. All unemployed people are graduates
Explanation
The unemployed graduates may all lie outside the engineer group, so nothing definite follows about engineers either way. The pattern of an all premise followed by a some premise on the wrong term is a standard trap. Only when the particular premise connects to the right term does a conclusion emerge.

About Syllogisms
Syllogisms use categorical statements such as all, some and no to establish relationships between groups. Questions require checking whether conclusions necessarily follow from the premises, often by mental set relationships or Venn diagrams, and distinguishing valid deductions from conclusions that are merely possible.
