Question

All Astronauts are Smokers. All Drivers Ski. Some Astronauts are Drivers. Kamlesh is an Astronaut. Which of the following necessarily follows?
I. Kamlesh Skis
II. Kamlesh does not Ski
III. Kamlesh is a Smoker
IV. Kamlesh is not a Smoker
V. Kamlesh is a Driver
VI. Kamlesh is not a Driver
Select the most appropriate response:

• A. Only III and VI
• B. Only I follows
• C. Only I and V
• D. All follow

Hint:

For syllogism with partial overlaps, identify what is always true versus what may or may not be true.

Answer 1

The Correct Option is A

Step 1: Analyze statements —
All Astronauts ⊆ Smokers → Kamlesh is a Smoker (III).
Some Astronauts ⊆ Drivers → Kamlesh may or may not be a Driver → Kamlesh is not necessarily a Driver → VI may follow if assuming he is not among the “some.”
All Drivers ⊆ Ski → Cannot conclude if Kamlesh Skis, as we do not know if he is a Driver.
Step 2: Evaluate conclusions —
I & II → Cannot be concluded.
III → True
IV → False
V → Cannot be concluded
VI → Can be assumed in absence of evidence to the contrary.
Step 3: Conclusion — Only III and VI follow.
