Question

omar set up five pairs of platform bird feeders around his yard. he filled one feeder in each pair with sunflower seeds and the other feeder with flax seeds. for one week, omar watched cardinals visiting the feeders during the same hour each morning. during his observations, omar counted the number of visits by cardinals to feeders with sunflower seeds and the number of visits by cardinals to feeders with flax seeds.

identify the question that omar’s experiment can best answer.

do cardinals eat more seeds per visit from feeders containing sunflower seeds compared to feeders containing flax seeds?

do cardinals visit feeders containing sunflower seeds more often than feeders containing flax seeds?

Explanation:

Omar's experiment involves comparing the number of cardinal visits to feeders with sunflower seeds and flax seeds. The question "Do cardinals visit feeders containing sunflower seeds more often than feeders containing flax seeds?" directly relates to the frequency of visits (how often) between the two types of seed - filled feeders, which is what the experiment's data (counting visits) can answer. The other question about "more seeds per visit" isn't addressed as the experiment only counts visits, not the amount of seeds eaten per visit.

Answer:

Do cardinals visit feeders containing sunflower seeds more often than feeders containing flax seeds?
