Answer:
Paraphrase.
Step-by-step explanation:
In this scenario, Geoffrey has come across an article that provides some interesting insights into the works of Samuel Clemens. One of these paragraphs would apply to his current English literature course but is very long. Geoffrey decides to paraphrase the main ideas of the paragraph by putting them into his own words and crediting the original author.
Paraphrasing can be defined as an act of rephrasing the words contained in a text without changing or altering the meaning of the text.
This ultimately implies that, Geoffrey decided to restate the main ideas of the paragraph by putting them into his own words so as to clarify its meaning.
