II. No guava is a date.

Options for question 63

Show the answer and explanation
CorrectNot quiteAnswer A

Correct answer: A

Explanation

  1. The guavas that are figs are dates, so some guavas are dates: I follows.

  2. Conclusion II contradicts I, so it is definitely false.

  3. Either-or needs neither conclusion to follow alone. Here I follows, so the answer is only I.

Worth noting

A complementary pair is not automatically 'Either I or II'. Check first whether one of them follows by itself.

Concept
Either-or applies only when neither follows alone
