A naked mole rat colony, like a beehive, wasp’s
nest, or termite mound, is ruled by its queen, or reproducing female. Other
adult female mole rats neither ovulate nor breed. The queen is the largest
member of the colony, and she maintains her breeding status through a mixture of
behavioral and, presumably, chemical control. Queens have been long-lived in
captivity, and when they die or are removed from a colony one sees violent
fighting for breeding status among the larger remaining females, leading to a
takeover by a new queen.
Eusocial insect societies have rigid
caste systems, each insect’s role being defined by its behavior, body shape, and
physiology. In naked mole rat societies, on the other hand, differences in
behavior are related primarily to reproductive status (reproduction being
limited to the quee
A. Naked mole rat colonies exhibit social organization based on a rigid caste system.
B. Behavior in naked mole rat colonies may well be a close vertebrate analogue to behavior in eusocial insect societies.
C. The mating habits of naked mole rats differ from those of any other vertebrate species.
D. Naked mole rat colonies are the only known examples of cooperatively breeding vertebrate societies.

[填空题]Some consumer researchers distinguish between "rational" motives and
"emotional" motives. They use the term "rationality" in the traditional
economic sense that assume that consumers behave rationally when they (1)______
carefully consider all alternatives and choose those that give them the greatest
utility (i.e. satisfaction) in a marketed context. The term "rationality" (2)______
implies that the consumer selects goods based on totally objective criteria,
such as size, weight, price, and so on. "Emotional" motives imply the
selection of goods according to impersonal or subjective criteria--the desire for (3)______
individuality, pride, fear, affection or status.
The assumption underlying this distinction is that subjective or
