In this speech, Demosthenes tries to warn people about an attack on Greece. Which statement best describes Demosthenes's claim?

Demosthenes warned of Macedonia's claims.

Explanation:

During the reign of King Philip II of Macedonia, Demosthenes regularly emphasized the efforts of the King of Macedonia to conquer Greece. Philip II. wanted to capture Greek policies fraudulently, as Demosthenes warned and devoted most of his life to fighting Macedonian expansion. With his speeches, he glorified Athens and sought to preserve the freedom of the city, but also to establish an alliance against Macedonia. But he failed in this, and eventually, Greece fell under Macedonian rule. And if he was one of the greatest rhetoricians in Greek history, he failed in his plans.
