Self-study
All people prefer colors that they can distinguish easily to colors that they have difficulty distinguishing. ███████ ███ ██████ ███████████ ██████ ██████ ████ ██████ ███████ ████ ██████████ ██████████████ ██████ ███████ █ ████████ ███████ ███ ███ ███████ █████ ██████ ████ ███ ████ ███ ██ ██████ ██████ ██ ███ ████ ██████
Summary
The stimulus tells us that all people prefer colors that they can easily distinguish. And it turns out that infants can easily distinguish bright colors, but not subtle shades. We also know that brightly colored toys for infants sell better than comparable, subtly colored toys.
Strongly Supported Conclusions
The stimulus strongly supports the conclusion that infants prefer bright colors over subtle colors. The stimulus also supports the conclusion that the sales of toys for infants match this color preference (although we can't determine any causality).

Which one of the following ███████████ ██ ████ ████████ █████████ ██ ███ ███████████ ██ ███ ████████
a
Infants prefer bright ███████ ██████ ██ ██████ █████████ ███████
This answer is unsupported. We don’t know from the stimulus whether infants have any preference between primary and secondary colors. We only know that infants prefer bright colors in general, because they can easily distinguish bright colors.
b
Color is the ████ █████████ ██████ ██ ███████████ █████ ████ ██ ██████ ████ ██████ ██ ████ █████
This answer is unsupported. The stimulus says nothing about what toys an infant will or won't play with; we only have information about infants' color preferences and toy sales trends.
c
Individual infants do ███ ████ ██████ ███████████ ███ ███ ██████████ ██████ █████ ████ █████ ██████ ███████
This answer is unsupported. The stimulus addresses the preferences of infants generally. We don’t know either way whether any individual infant strongly prefers yellow, say, over green
d
The sales of ████ ███ ███████ ███████ ███ ███████████ ██ ███████ ██ ██ █████ ███ ████████
This answer is strongly supported. We know that everyone prefers colors they can distinguish, and that infants can distinguish bright colors, but not subtle colors. This lets us infer that infants prefer bright over subtle colors. Brightly colored toys sell better than subtly colored toys. Hence, toy sales reflect infants' preferences, at least with regards to color.
e
Toy makers study ███████ ██ █████████ ████ ██████ ███ ███████ ███ ███████████ ███████
This answer is unsupported. Nothing in the stimulus addresses toy makers' perspective or design process.
