Set 5: Inferences

Explanation

Answer: A

PASSAGE

Flamingos are born with gray feathers. Their iconic pink color develops over time as they consume shrimp and algae containing carotenoid pigments. In zoos, without access to their natural diet, flamingos can fade to white unless given pigment supplements.

What can be inferred about flamingo coloration?

A. It is significantly influenced by diet rather than inherited traits alone.✓ Correct

B. Flamingos prefer to be white.

C. It is entirely determined by genetics.

D. Zoo flamingos are always more colorful than wild ones.

Detailed Explanation

This question asks you to draw a logical conclusion from the text. Born gray, becoming pink from diet, fading without it—coloration depends on eating specific pigments. A valid inference must be supported by evidence in the passage, even if not stated directly. Look for clues in the text that strongly suggest the answer. Avoid conclusions that require assumptions beyond what's written. Valid inferences are strongly supported by multiple pieces of evidence in the text. Be cautious of choices that go too far beyond what the passage actually states. The best inference is the one most directly supported by textual evidence.

Key Evidence:

• "develops as they consume shrimp and algae"

• "fade to white unless given supplements"

Why others are wrong: B (Preference isn't discussed.), C (Diet, not just genetics, determines color.), D (Zoo flamingos can fade without supplements.).
