Self-study
Support Insects can see ultraviolet light and are known to identify important food sources and mating sites by sensing the characteristic patterns of ultraviolet light that these things reflect. ███████ ███ ████ █████████ ██ ████████ ███████████ █████ ███████ ███████████ ██████ █████ ███████ ███ ████████ █████████ ██ █████ ████ ███████ ██ ███ ████████ ████████ ██ ███████████ █████ ████ █████ ████ ████████
Summarize Argument: Phenomenon-Hypothesis
The author hypothesizes that insects are attracted to Glomosus spiderwebs due to the specific patterns of ultraviolet light these webs reflect. This is because insects use ultraviolet light patterns to find food sources. What's more, Glomosus spiderwebs, which reflect ultraviolet light, are known to attract insects.
Notable Assumptions
The author assumes that the Glomosus spiderwebs consistently reflect specific patterns of ultraviolet light. The author also assumes that insects aren’t attracted to Glomosus spiderwebs for some other reason.

Which one of the following, ██ █████ ████ ████████ ████████ ███ █████████
a
When webs of ████ █████████ ███████ ██ ██████ ████ ███████████ ████ █ ███████ ██████ ██ █████ █████ ██████████ ██ ███████████ ██████████ ████ ██ █████ ████ ███ ███ ███████ ███ ███████████ ██████
This is irrelevant. Without more information about how insects behave around these webs compared to Glomosus webs, the reflective properties of other spiderwebs don't matter.
b
When the silks ██ ███████ ████ ████ ████ ████ ███ ██████ ███████ ███ ████████ ████ ████ ███████████ ████ █████ █████ ██████████ ██ ███████████ ██████████ ███ █████ ██ █████ ███████ █████████ ███████████ ██████
This is irrelevant. Maybe there's a reason that non-insect-catching spiderwebs sometimes reflect ultraviolet light, but whatever the reason, it doesn't change why insects are attracted to Glomosus spiderwebs.
c
When webs of ███ █████████████ ████████ ███████ ██████ ██████ ██████ ████ ███████████ ████ █████ █████ ██████████ ██ ███████████ ██████████ ████ ███████ ████████ ██ █████ ████ █████████ ███████████ ██████
This is irrelevant. Without more information about whether these webs attact insects, and the specific patterns of ultraviolet reflection compared to Glomosus spiderwebs, this isn't useful.
d
When Drosophila fruit █████ ████ ██████ ██████ █ ████████ ███ ███ █ █████████ ███ ██ ███████ ███████ ████ ████ █████████ ███████████ █████ ███ ████ ████ ████ ███████████ ████ █████ █████ ██████████ ██ ███████████ ██████████ ████ ██ ███ █████ █████ ████ ██ ███ ████████ ████
Remember, "many" doesn't mean "most". This gives us no useful information, we still don't know if one web was more attractive than the other. This doesn't help us determine why Glomosus spiderwebs attract insects.
e
When Drosophila fruit █████ ████ ██████ ██████ ███ ████████ █████ ███ ███████████ ████ █████ █████ ██████████ ██ ███████████ █████████ ███ ███ ███████████ ████ █████ █████ ███████ ██ ███████████ ██████████ ███ ████████ ████ ██ ███ ███████████ ██████████ ████
Between the otherwise identical Glomosus spiderwebs, most insects chose the one with ultraviolet reflections. This strengthens the idea that ultraviolet reflections, and not something else about the spiderwebs, are what attract insects.
