Set 5: Inferences

Explanation

Answer: B

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 entirely determined by genetics.
B. It is significantly influenced by diet rather than inherited traits alone.✓ Correct
C. Zoo flamingos are always more colorful than wild ones.
D. Flamingos prefer to be white.

Detailed Explanation

Born gray, becoming pink from diet, fading without it—coloration depends on eating specific pigments.

Key Evidence:

• "develops as they consume shrimp and algae"

• "fade to white unless given supplements"

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