According to the passage, which of the following statements is FALSE?

  • A.Feather colours are the result of a combination of pigment and structural colours.
  • B.Yellow, orange and red hues do not come from pigments in the food they eat.
  • C.A preen gland is located at the base of the tail which secretes an oil that repels water.
  • D.The scales are occasionally shed by a process called moulting.

Answer: B

The false statement is that yellow, orange and red hues do not come from pigments in the food they eat. The passage says carotenoid pigments, which give yellows, oranges and reds, originate at least in part from the food, so the statement is false.

The other three are true to the passage: feather colours result from pigment and structure, the preen gland at the base of the tail secretes an oil that repels water (the passage says it is important in waterproofing the plumage), and scales are occasionally shed.
