Meter gives poetry a predictable rhythm and influences how a poem is read, both silently and aloud. what is the basic unit of meter in poetry? a foot a trochee an unstressed syllable an iamb

The basic unit of meter in poetry is a foot.
Syllable would be the correct answer if the option said 'stressed or unstressed syllable,' because there are two types of syllables, not only the unstressed one. An iamb and a trochee are types of feet in poetry, so they are incorrect as well. A foot is a unit of meter which consists of a number of syllables. 

Ibelieve the correct answer is  d. they bound logs together and built a raft. enkidu steered it down the great river. gilgamesh carried humbaba's head.we know that gilgamesh was triumphant in this battle because he is carrying his enemy's head. he defeated humbaba, and then decapitated him to have his head as a trophy, or to show it to everyone that he managed to defeat his enemy.
