Passage II

Meerkats (Suricata suricatta) are mammals that typically live in groups of 2 to 30 individuals. Some group members called helpers, help parents care for their pups. Figure 1 shows how the percent contribution to babysitting and to pupfeeding by helpers varied with the age of the helpers, as categorized in Table 1.

A helper's food intake, as measured by daily weight gain (average number of grams gained by a helper per hour during a 24 hr day), can affect its contribution to pup care. Figure 2 shows how the percent contribution to babysitting and to pupfeeding by helpers older than 1 yr varied with daily weight gain.

8. Based on Table 1 and Figure 1, the greatest difference between the percent contribution by male helpers and the percent contribution by female helpers was observed for which pup care activity and which helper age range?

Answer and Explanation

Your Answer is

Correct Answer is G

Explanation
