Question

which statement expresses the main theme of the poem?
life is temporary and is usually unnoticed or forgotten by others.
day, night, and the ocean are all on a rising and falling cycle of time.
human activity is random and frantic, but the tide is constant.
an oceans tide moves in predictable currents.

Explanation:

To determine the main theme of a poem, we analyze each option:

• The option about day, night, and ocean cycles is too narrow and focuses on natural cycles rather than a broader theme.
• The option about human activity and the tide compares human chaos to the tide's constancy, but this is more of a contrast than a main theme about life's nature.
• The option about the ocean's tide currents is a factual statement about tides, not a thematic statement about life or human experience.
• The option "Life is temporary and is usually unnoticed or forgotten by others" addresses a broader thematic idea about the nature of life, which is a common theme in poetry, focusing on the transience and often overlooked nature of life.

Answer:

Life is temporary and is usually unnoticed or forgotten by others.
