PrepTest 43, Section 2, Question 25
Burying beetles do whatever they can to minimize the size of their competitors' broods without adversely affecting their own. This is why they routinely destroy each other's eggs when two or more beetles inhabit the same breeding location. Yet, after the eggs hatch, the adults treat all of the larvae equally, sharing in the care of the entire population.

Which one of the following, if true, most helps to explain burying beetles' apparently contradictory behavior?
Burying beetles whose eggs hatch before their competitors' are more likely to have large broods than are burying beetles whose eggs hatch later.
The cooperation among adult burying beetles ensures that the greatest possible number of larvae survive.
Burying beetles are unable to discriminate between their own larvae and the larvae of other burying beetles.
Many of the natural enemies of burying beetles can be repelled only if burying beetles cooperate in defending the breeding site.
Most breeding sites for burying beetles can accommodate only a limited number of larvae.
