Explain why the researchers in the Hassett et al. (monkey toy preferences) study believed it was necessary to analyze the social rank of the monkeys in relation to their toy choices.

In the study by Hassett et al. (monkey toy preferences):
(a) Identify the species of monkey used as participants and the size of the initial troop from which they were selected.
(b) The researchers categorized the toys into two distinct types. Name both categories and provide one specific example of a toy used in each category.

Regarding the methodology and procedure of the Hassett et al. study:
(a) Describe how the toys were positioned in the outdoor enclosure during the trials and explain the reason for this specific arrangement.
(b) The researchers utilized a behavioral checklist to measure toy interaction. Describe two specific behaviors, other than simple contact, that were recorded by the observers.
(c) Outline how the researchers ensured that the observations were reliable.
