Answer:
You must use an internal citation to indicate the source.
Explanation:
When we use a direct quote in a piece of writing, we take a passage or set of words from another person or source and repeat them exactly as he or she said it and put this information between quotation marks. On the other hand, when we use an indirect quote, we do not repeat the same exact words of the original form but we convey his or her ideas with our own words, without the quotation marks. In either case, it is essential that we indicate the source (who said it) of the information we are referring to.
Simon Bolivar once said, "The Ignorance the people live in leads them to commit mistakes against their own happiness" (Direct quotation).
Simon Bolivar believed that the ignorance the people leave in is what leads them to commit mistakes against their own happiness (Indirect quotation).
