Self-study
In a study, infant monkeys given a choice between two surrogate mothers—a bare wire structure equipped with a milk bottle, or a soft, suede-covered wire structure equipped with a milk bottle—unhesitatingly chose the latter. ████ █████ █ ██████ ███████ █ ████ ████ █████████ ████████ ████ █ ████ ██████ ███ █ █████ █████████████ ████ █████████ ███████ █ ████ ███████ ████ ██████████████ █████ ███ ███████
Summary
A study examined monkeys given a choice between a bare wire structure with a milk bottle or a soft, suede-covered structure with a milk bottle as surrogate mothers. The monkeys chose the soft, suede-covered structure. In a separate experiment where the suede-covered structure did NOT have the milk bottle, the monkeys preferred the bare wire structure that still had the milk bottle.
Strongly Supported Conclusions
Monkeys prefer a milk bottle over softness of texture when choosing a fake surrogate mother.

Which one of the following ██ ████ █████████ ██ ███ ███████████ ██████
a
Infant monkeys' desire ███ ██████ ███ ███████ ██ ██████ ██ ██████ ██ █████ ██████ ███ █████
This is anti-supported because the experiment shows that the infant monkeys rejected the comforting structure in favor of one that had food. This does not indicate a near equality in desires.
b
For infant monkeys, █████ ██ █ ████ ██████████ ██████████ ███ █████ ████████ █████ ████ ██████ ███ █████ ███
This is unsupported because the experiment never tested suede against real animal fur.
c
For infant monkeys, █ ████ ██████ ██ █ ████ ██████████ ██████████ ███ █████ ████████ ████ ████ █████ ██ ███ █████ ████████ ██████
This is anti-supported because the monkeys tended to prefer the bare structure with the milk bottle over the suede structure that had no milk. We also don’t know how convincing each structure was at replicating the real thing.
d
For infant monkeys, █ ████ ██████ ██ ██ ███████ ██████████ ██████████ ███ █████ ████████ ████ ██ █████ ██ ███ █████ ████████ ██████
This is anti-supported because the infant monkeys tended to choose the bare structure with the milk bottle more than the suede structure without the milk, indicating an inequality in how convincing each substitute is.
e
Infant monkeys' desire ███ ████ ██ ████████ ████ █████ ██████ ███ ██████ ███ ████████
This is strongly supported because when the monkeys had to choose between a bare wire structure with food versus a soft structure that had no food, the monkeys chose the uncovered structure with food.
