Logical reasoning PrepTest 118 · Section 4 · Question 16

Incorrect. This answer choice neglects finding happiness in one's personal life.

Incorrect. If anything, the argument supports the conclusion that family (and friendship) is the only place one can be happy, so it can't be undermined.

Incorrect. While the argument establishes that most people could only be happy in their personal lives, it doesn't establish that most actually are. Sadly, happiness could be rare based on the information in the stimulus.

Incorrect. The argument is about people feeling needed/appreciated, not appreciating their work.

Correct. Argument or Facts:
Argument

Valid or Flawed:
Flawed

Question Type:
Must Be True

Stimulus Summary:
not Feel needed → not Happy (Happy → Feel needed)
Most can feel needed only with family and friends
Most know their job could be done by others

Answer Anticipation:
The argument establishes that feeling needed is a necessary part of being happy. It also establishes that most people can't feel needed in their professional lives, so they therefore can't feel happy because of that aspect of their lives. Only in their private lives can they feel needed, so only there can they derive happiness.

So, putting the conditional together with the two areas of life discussed:
Most people can't be happy in their professional lives.
Most people can only feel happy in their private lives.

Answer Explanation:
"Fewer than a majority" is a fancy way of saying "Most don't/can't." So simplifying the language here, this answer says, "Most people can't find happiness outside of their private lives." That's a logically equivalent rephrasing of our inference from the stimulus that most people can only find happiness in their private lives, so this is the correct answer.

Key Takeaway:
In Must Be True questions, focus on conditionals when present! Even if they don't chain together to form inferences, they can frequently be applied to information presented in other statements in order to lead to those inferences.
