I don't see a poem, but I can tell you how to determine the meter of a poem.
The meter of a poem is determined by the last word in a line.
For example,
Roses are red, A
Violets are blue, B
sugar is sweet, C
And so are you. B
You rhymes with blue so so they are both blue.
Tell me if you need more info:D
Answer:
A reader needs to ask, what does the author want to convince you of.
Explanation:
If asking the authors position, you will only find the opinion of the author. While this can also be used to find a claim it isn't always the most effective.
If asking what the issue is in general, you can't find the authors claim from the start.
If asking the reasons, that will help you find the reasoning, not the claim.
I believe you have to write up your own. I hope this comes in handy^-^
