medium · LSAT Logical Reasoning
A rule states: if you are 18, you can vote. A particular person is 21. It is concluded that this person can vote.
Strictly on the basis of the rule as stated, is this inference valid?
- Yes, this is modus ponens.
- No, because being 21 fails to match the exact triggering condition the rule specifies.
- Yes, because 21 is plainly greater than 18.
- No, because it affirms the consequent.
- No, because no rule about a single age can ever speak to voting eligibility.
