Passage
The common grackle is one of the most abundant species of bird in North America. When two male grackles encounter each other, there is often a threat display (a loud, abrasive call). The dominant male usually forces the submissive male to cower and eventually fly away. A biologist conducted two experiments to determine the rank in aggression in male grackles. In the experiments described below, five adult male birds were placed together in a cage and their interactions were observed and recorded.
Experiment 1
To determine what factors might affect aggressiveness, the biologists recorded the sequence in which the birds were placed in the cage, their weight, their ages, and the number of calls each grackle made during the experiment. In addition, the birds were ranked according to their aggressiveness toward each other, from most aggressive (1) to least aggressive (5). The results are shown in Table 1.

Experiment 2
The male grackles were placed back into the cage in the same sequence as in Experiment 1. The results of all aggressive encounters (number of calls) between pairs of birds were recorded. A bird was declared a “winner” if it forced the other bird, the “loser,” to flee from the encounter. Table 2 shows the results of the interactions between the birds. There were no draws (ties) observed.

Table 3 summarizes the results of all the encounters for each bird.
Q. A sixth grackle, whose body weight was 330 grams and whose age was 24 months, was added to the experimental cage. It was observed that the bird called a total of 10 times during the experiment. Based on the results of Experiment 1, what would be the rank of the sixth grackle in terms of its aggressiveness?
  • a)
    3
  • b)
    4
  • c)
    5
  • d)
    6
Correct answer is option 'D'. Can you explain this answer?

To solve this problem, compare the values given with the values listed in Table 1. Based on those values, the sixth grackle is most similar to Grackle D, which had an aggression rank of 5. However, because the sixth grackle had fewer calls, it would be less aggressive, and so would likely have a lower rank.
