Incorrect. The stimulus discusses her friends's feelings towards black tea, not Samantha's, so this could be true.

Incorrect. This answer can be tempting since it says that none of Samantha's friends like both oolong and green tea, so it can feel as if some must like each one. However, if they all like oolong tea and dislike green tea, then it'd be true that none like both, so this answer is possible and thus incorrect.

Incorrect. Similar to (B), it's possible that they all like black tea, and then have the same oolong/green tea preference (as long as they all don't like both). This answer is therefore possible and wrong.

Incorrect. Someone who likes neither oolong or green tea does not like both, so this is also possible.

Correct. Argument or Facts:
Facts

Question Type:
Cannot Be True

Stimulus Summary:
Samantha — Likes oolong tea; likes green tea
Samantha's friends — Like black tea; none like both oolong and green tea

Answer Anticipation:
This stimulus presents what seems like relatively straightforward information about Samantha, her friends, and their tea preferences. However, there's one statement that we need to make sure we understand before moving to the answers.

That statement is that none of Samantha's friends like both oolong tea and green tea. What does that actually mean? Well, it means that, if you're a friend of Sam, you dislike oolong tea, green tea, or both. The one thing you can't do is like both oolong and green tea.

With that in mind, let's head to the answers and find one that is contradicted by this information.

Answer Explanation:
Samantha likes oolong and green tea, but none of her friends do, so none of her friends can like all the same kinds of tea as Samantha. Since this answer is directly contradicted by information in the stimulus, it's the correct answer.

Key Takeaway:
Cannot Be True questions have correct answers that are directly contradicted in the stimulus. An answer that is technically possible but seems very unlikely is still possible and thus incorrect.
