Instructions: Below is a conditional. Assume that it is true. You will be given an additional fact, which you should assume is true. You will finally be given a conclusion, starting with "Thus." If both the conditional and the additional fact were true, would the conclusion have to be true? If so, pick YES. If not, pick NO.

Conditional:

If someone swims within 30 minutes of eating, then they will get a cramp.

Fact:

Lux got a cramp.

Conclusion:

Thus, Lux swam within 30 minutes of eating.

Answer: If you assume that the conditional and fact above are true, must the conclusion also be true?

Yes, the conclusion must be true if the conditional and fact are true.

No, the conclusion might be false even if the conditional and fact are true.
