Options for question 39

Show the answer and explanation
CorrectNot quiteAnswer B

Correct answer: B

Explanation

  1. Every crow is a raven and every raven is a finch, so every crow is a finch.

  2. Those finches (the crows) are not sparrows, because no sparrow is a crow. Some finches are not sparrows: II follows.

  3. Sparrows are kept out of the crow circle only. They may still be finches, so I is not definite.

  4. Only II follows.

Worth noting

An exclusion from the small group (crows) never passes up to the bigger group (finches).
