Read the passage.
after the trumpet was sounded and the flag folded, a member of the honor guard knelt in front of my frail, aging mother, looked her directly in the eye and in a soft voice, her — and my father—for his service.
which detail is most in revealing the writer's desire for her reader to sympathize with her mother?
her mother is frail and aging.
her father was a veteran.
the serviceman is her mother.
this happened after a funeral.

Refute it, showing why it is mistaken—an apparent but not real problem; acknowledge its validity or plausibility, but suggest why on balance it's relatively less important or less likely than what you propose, and thus doesn't overturn it; concede its force and complicate your idea accordingly—restate your thesis in a more exact, qualified, or nuanced way that takes account of the objection, or start a new section in which you consider your topic in light of it. this will work if the counterargument concerns only an aspect of your argument; if it undermines your whole case, you need a new thesis.
