Answer:
Selecting and forming a claim about a specific topic.
Identifying evidence to include to support your reasons.
Investigating counterclaims that go against your claim.
Explanation:
An argumentative essay is one that argues for or against any given issue. This means that the paper must include or contain evidence for the arguments made, support the claims, and thus, making a persuasive presentation.
In writing this type of essay, the prewriting steps will include the selection of the claim or argument that will be the focus. Then comes the identifying of evidence, as support for the argument. Also, investigating any counterclaims that argue against the claims made is also part of the prewriting steps.
Thus, the correct answers are the first, second, and third options.
