Which describes an effective source A one written by a witness to an event B one written by an expert on the topic C one that supports the ideas in a project D one that is long and complex

Answer 1

An effective source is best described as B: one written by an expert on the topic. This is because expert sources typically provide reliable, well-researched, and informed perspectives on a subject matter. While firsthand accounts (A) can be valuable, they may lack the analytical depth or context provided by an expert. Sources that simply support existing ideas (C) can be biased and may not offer a balanced view. Lastly, a source that is long and complex (D) is not necessarily effective; clarity and relevance are more important than length.
