Answer 1

A student completing research for a project enters the following search terms:

Pets AND diet NOT birds

The answer which best describes the likely results of this search is the last one - Sources that reference the diet of pets but not birds. 

Answer 2

The correct answer is D. Sources that reference the diet of pets but no birds

Explanation:

Online or similar searching tools work based on keywords and in some cases connectors and conjunctions introduced in the browser. In this way, results are based on the keywords introduced and how these are connected. Considering this, by introducing "Pets and diet not birds" the main terms are "pets and diet" that would result in information that mixes both words, however by adding "Not birds" the results in which "birds" appear "in pets and diet" will be excluded as "not" express denial or refusal. Thus, while the use of "and" in "pets and diet" make the browser look for results in which both terms are included, the use of "not" in "not birds" excludes birds from those results, due to this, the results of this search will probably be sources including the diet of pets, but no birds.
