I'm asking about the poem "grass" by carl sandburg..if it has a metaphor or not? and if it has in which line can i see the metaphor?

Explanation :

Carl Sandburg's short poem "Grass" represents a metaphor for the disguise of history. The persona tells how histories that have taken place are sooner or later disregarded. The persona tells that the histories should not be disregarded, but be left the way it is as cited in the poem "I am the grass .Let me work." People should notice the events that took place and learn from their mistakes and be better people. The places that are mentioned in the poem are allusions. The allusions are indirect references that Carl Sandburg utilizes to exhibit the seriousness of the past events.

faulty parallelism is a construction in which two or more parts of a sentence are equivalent in meaning but not grammatically similar in form.

the correct version of this faulty parallelism in the sentence is:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

the problem is the last sentence, the first two have a basic subject+verb+object structure.

so, to give a proper balance to the structure, or better said, to give a parallel structure, we must write a basic s+v+o structure in all three sentences:

the hikers knew that the hike was six miles, that it usually required the entire day, and it would not be wise to start after 10: 00 a.m.

what is the context here? we need to know what story you're talking about : )
