Like all species of baleen whales, the humpback whale feeds on tiny creatures known as krill by filtering water through bristlelike keratin structures called baleen plates. In this way, baleen whales can eat up to 30 percent of their total mass per day. And while no one would call the humpback whale small-it can have a mass as high as 30,000 kg-it is one of the smaller baleen whales and is much smaller than the northern right whale, which can weigh a whopping 80,000 kg and consume as much as 24,000 kg of krill per day.
Which choice best describes the overall structure of the text?
It describes a characteristic shared by all baleen whales and then illustrates a difference between the humpback whale and the northern right whale that is relevant to that characteristic.
A
It discusses a unique feature of the humpback whale and how the lack of that feature in the northern right whale explains differences in the two species' behavior.
B
It draws a distinction between the sizes of the humpback whale and the northern right whale and then presents a feature that they have in common.
C
It details a relationship between humpback and northern right whales and krill and then discusses an unexpected consequence of a change in baleen whale populations.
D
