Question

1. which boolean operator would you use if you wanted to search for \sea birds\ and include penguins?

and, +
not, -
or, |

Explanation:

The Boolean operator "OR" is used to include multiple related terms in a search. When we want to search for "sea birds" and also include penguins (which are a type of sea bird), using "OR" ensures that results containing either "sea birds" or "penguins" are retrieved. The "AND" operator would be used if we wanted results that have both specific terms (e.g., "sea" AND "birds"), and the "NOT" operator is used to exclude terms.

Answer:

OR, |
