PrepTest 146

Incorrect. There's no indication that these fish will die without special care. The closest is that they'll be underfed if housed with ordinary fish, but they could just be housed alone.

Incorrect. While the brilliant coloration and unusual body shapes of especially bred fish are noted as being popular with connoisseurs, that doesn't imply that fish without these features don't interest these connoisseurs—they may have a lower level of interest in them, but interest nonetheless.

Incorrect. While these fish are popular with connoisseurs, they may also be popular with the general public—and the general public almost certainly outnumbers the connoisseurs to the point where they may buy significantly more of these fish.

Correct. Argument or Facts:
Argument

Valid or Flawed:
Flawed

Question Type:
Must Be True

Stimulus Summary:
Specially bred fish . . .

1. Popular with connoisseurs
2. Hampered in swimming by tails/fins and thus are outcompeted for food by ordinary fish
3. Have ugly babies

Therefore, they're inferior to ordinary fish.

Answer Anticipation:
This Must Be True question features an argument, but remember that we're still supposed to treat all of the information in the stimulus as true—even the conclusion.

Here, the stimulus describes specially bred aquarium fish in a number of ways and compares them to ordinary fish in a few of them. A specific anticipation is difficult here since the statements are essentially a list of cons, so we should leave time to analyze the answers.

Answer Explanation:
The specially bred fish are noted as being less able to quickly reach food than ordinary fish because of these features. Since the features are noted as what's causing them to be slower than ordinary fish, it's implied that these ordinary fish lack these features, and thus this answer is supported.

Key Takeaway:
Must Be True questions with comparative statements generally use those comparisons to support the correct answer. Be on the lookout for comparisons as you work through the stimulus!

Incorrect. These features hamper their ability to reach food quickly, but they're not connected to being hampered in their ability to reproduce. It's also not even established that they are hampered in their ability to reproduce—having ordinary offspring is still having offspring, so the ability is still there.
