Explanation:

Analyze sentence 4 in context

Using the Essay Revision knowledge point
Sentence 4 states: "Opponents argue that tablets aren't a good choice because initially they're very expensive." This sentence is part of a persuasive essay arguing that schools should switch to digital tablets. Persuasive essays in academic settings require a formal tone and register.

Evaluate the options

• Option 1 ("by replacing the word 'argue' with the word 'fight'") makes the tone overly aggressive and informal.
• Option 2 ("by deleting the entire sentence from the paragraph") is incorrect because sentence 4 introduces a counterclaim, which is a crucial element of argumentative structure.
• Option 3 ("by changing 'aren't' to 'are not' and 'they're' to 'they are'") removes informal contractions, establishing a formal academic tone.
• Option 4 ("by moving the sentence to the end of the paragraph") disrupts the logical flow of the argument.

Select the best revision

Replacing contractions with their full forms is a standard revision rule to elevate informal writing to a formal academic standard. Therefore, Option 3 is the correct revision.

Answer:

• by replacing the word "argue" with the word "fight"
• by deleting the entire sentence from the paragraph
• by changing "aren't" to "are not" and "they're" to "they are" (Correct answer)
• by moving the sentence to the end of the paragraph
