Frankly, I think the author is being a bit disingenuous. Question 5 for example: What function does the stanza break serve? She says she put it where it is because she's a performance poet and thought it should go there. One, that isn't the question. The question isn't asking about the author's subjective state of mind, but to remark on the objective function of the stanza break. The subject of the poem clearly shifts at that point from reflecting on the weekend to talking about the anxiety of the upcoming day. Out of the answers presented, (C) is clearly the best answer. Two, the author's point simply begs the question. The break sounds good there because there is a structural break in the underlying poem. Her subjective impression of where the break should go reflects an objective fact about the structure of the poem.
The other questions are likewise quite straightforward. The website doesn't reproduce the full test booklet, but I suspect the prompt does not ask for the "right answer" but "the best answer out of the choices presented." The test is not asking students to plumb the depths of the author's pscyhe, but evaluate consistency or inconsistency between each answer choice and the objective aspects of the poem. It's not an exercise in literary analysis, it's an exercise in reading (knowing the meaning of words) and logical analysis.
Take Question 6: "The train is important to the poem because it represents..." Who knows what the author meant the train to represent? But to an objective observer, C ("following a planned routine") clearly "fits" the text better than the other answers. That's all the test is asking students to figure out.
