Answer:
The correct answer is B.
Explanation:
The excerpt from Tinker v. Des Moines that shows how precedent helps support an argument is: "Other cases cited by the Court do not, as implied, follow the McReynolds reasonableness doctrine. West Virginia v. Barnette, 319 U.S. 624, clearly rejecting the 'reasonableness' test, held that the Fourteenth Amendment made the First applicable to the States". This excerpt shows how the Supreme Court uses decisions of other cases already resolved to support arguments within cases in decision at the moment .In the present case, the Court uses the precedent West Virginia v. Barnette, in which the doctrine of "reasonableness" of McReynolds is not admitted, to apply it to the case Tinker v. Des Moines.
