Which of the following is considered an incorrect answer in a Must Be True question?

In a Must Be True question, the focus is on identifying an answer choice that must logically follow from the information provided in the stimulus. The answers that are considered correct will closely adhere to the details given and will be directly supported by the information in the passage.

The reason why the specific choice identified as incorrect represents an answer that doesn’t fit the criteria is that "once in a while answers" imply occasional truths that do not consistently follow from the stimulus. Must Be True questions require answers that can be conclusively derived from the information given, rather than those that may happen just sometimes.

Choices that could be construed as possibilities, exaggerations, or ambiguous statements do not fulfill the requirement of being universally or necessarily true based on the provided premises. These types of answers may introduce variability or uncertainty, making them unsuitable for questions that demand an answer which must hold true under all circumstances implied by the passage.
