Source is author can use to research and develop ideas in an informational text.
a: autobiographical paper
b: outside publication
c: personal opinion
d: social network

According to the excerpt above, the correct answer to fullfil the incomplete sentence is letter B. “Source is an outside publication that an author can use to research and develop ideas in an informational text”. A source can be any specific publication or other type of media where specific information was obtained. These are usually included in footnotes, endnotes or any other bibliographical text; and also can be people.

That is because of the connotation. The denotation for house and home is a place of residence, however, our minds perceive the word house as neutral and generic while home is something that is close to us and brings us safety and security. That is an advertising ploy.
