Question

some species form social groups only with members of the same gender. for example, elephants form groups with only females and their offspring. once the male offspring reach a certain age, they leave the group and become solitary.
which is a benefit of this type of social group structure?

• females do not have to compete for a male.
• male offspring can belong to more than one social group.
• adult males can mate with females in several different social groups.
• females are the only ones responsible for taking care of the offspring.

Explanation:

1. Analyze Option A: In the described structure, females are in groups without males (except offspring who leave), so competition for males within the group is eliminated. But let's check others.
2. Analyze Option B: There's no info suggesting male offspring can belong to multiple groups; the text says they become solitary, so this is incorrect.
3. Analyze Option C: Since male offspring leave and become solitary, adult males can interact with females from different female - only groups, allowing them to mate with females in several different social groups. This is a benefit of the structure.
4. Analyze Option D: The text doesn't imply that females are the only ones responsible for offspring care as a benefit of the group structure (and it's not clear if this is a benefit or just a fact of the structure), and it's not a strong benefit compared to C.

Answer:

C. Adult males can mate with females in several different social groups.
