Complete Question Explanation
Must Be True—CE. The correct answer choice is (B)
In this stimulus, we learn about the dreadful results of whipping cream in a blender. The facts present a causal relationship:
Answer choice (A): This answer choice is tempting, because the author describes an instance in which ineffectively whipped cream becomes a “thick, velvety substance.” Note, however, that this particular effect results from whipping cream in a blender. There could be many alternative, equally ineffective ways of whipping cream that produce different results: some might cause the cream to separate and form butter, others might break it down into a soupy, runny, mess. We simply do not know if ineffective whipping techniques generally make the cream into a thick velvety substance. All we know is that they do that sometimes (when we use a blender).
Answer choice (B): This is the correct answer choice. At the end of the stimulus, the author remarks that the special attachment cannot fully compensate for the container’s poor air intake. Since the poor air intake is what prevents the cream from being whipped effectively (see the causal relationship above), we can conclude that the special attachment does not suffice to whip cream completely effectively: it only helps somewhat.
Answer choice (C): This answer choice contains an exaggeration. While we know that using a special attachment helps compensate for the container’s poor air intake, it is unclear whether it always produces a fluffier result. The language in the stimulus is rather tenuous (the attachment “helps somewhat”) suggesting that the outcome is neither perfect nor guaranteed.
Answer choice (D): This answer choice may seem attractive, because poor air intake is the reason why we cannot effectively whip cream in a blender, and the special attachment “helps somewhat.” It is unclear, however, exactly how the attachment helps. While it might help by reducing the amount of air required, it could also increase the amount of air available in the container. We simply cannot prove the exact means by which the special attachment helps whip cream in a blender, which makes answer choice (D) incorrect.
Answer choice (E): The stimulus contains no information to help us determine what the most common way of producing whipped cream is.
