Which search tool can you utilize to filter results by reading level?

The correct choice for filtering search results by reading level is Google Scholar. This specialized search engine focuses on scholarly literature and academic resources. Google Scholar provides features that allow users to refine their search based on various criteria, including the ability to filter results to specific reading levels. This can be particularly beneficial for educators and students who need resources that are appropriate for different stages of learning or comprehension.

Google Search, while extensive, does not offer a direct way to filter results by reading level in the same structured manner as Google Scholar. Google Images specializes in visual content; thus, it doesn't focus on reading levels at all. Similarly, Google Maps is designed for geographical and navigation purposes, which is outside the context of reading levels in research or educational material. Therefore, Google Scholar is the most suitable tool for achieving this specific filtering of search results.
