Question researched - This is basically asking you what they're trying to investigate. What question do they want to answer?
A good place to start is to read the abstract at the very top of the paper. Perhaps the most pertinent information in there, for this question, is:
"Although variation in mating signals among populations is known to affect mating behavior, there is no direct evidence that the evolution of mating signals changes signal effectiveness within a natural population."
We can basically rewrite that into a research question:
Since there is no direct evidence that evolution of mating signals change signal effectiveness, does variation in mating signals among populations (presumably of the same species) affect mating behavior?
Hypothesis/predictions - Most research studies will make a prediction, a hypothesis, about how their experiments will turn out. Or what their observations are like.
The most useful information comes from the introduction, second paragraph:
"The prediction that signal evolution may contribute directly to the formation of reproductive barriers is not well ...
