Which Boolean operator would a student use to find articles on both Chinese heritage and Native Americans?

The Boolean operator that allows a student to find articles that discuss both Chinese heritage and Native Americans is AND. When using AND in a search query, the result will return only those articles that contain all of the specified terms. This is particularly useful when you want to narrow down the search results to focus on a specific intersection of topics, in this case, articles that cover both Chinese heritage and Native Americans.

The use of AND ensures that the search does not return results that might only focus on one of the topics, thus providing a more precise set of articles relevant to both subjects. For example, if a student enters "Chinese heritage AND Native Americans," the search will yield results that mention both topics, making it a targeted approach in research. This is crucial for effective academic work, where specificity is often required.

In contrast, the other operators serve different purposes: OR expands the search to include articles related to either or both topics, NOT excludes specific terms from the search results, and XOR has a more complex application that is less commonly used in typical information searches. Thus, AND is the optimal choice for this kind of inquiry.
