Answer:
Becky began her introduction by using a quotation.
Explanation:
A quotation is a group of words or phrase taken from a source such as a text, book, etc. and repeated. It generally appears within quotation marks: " ". The text should be the same, without any changes.
In this case, Becky begins her introduction with a quotation about friendship by Vanessa Smith. She is using quotation marks and cites the author. This will give the introduction an impulse in order for Becky to begin and then settle on her own ideas.
