In looking up material for my recent goldenrod posting, I came across the site for the Herbal Extract Company, which claims to provide a goldenrod supplement for medicinal purposes. The site is a mess, with pages that look like templates, with no real content — like the goldenrod-sources page, which asks the question:
What foods are good sources of goldenrod?
but, so far as I can tell, provides no answers. My problem actually goes deeper than that, since I don’t understand the question. My guess was that it’s asking about sources of goldenrod ‘goldenrod extract’, in which case the sources are either goldenrod plants or companies like their own, but not foods. (In a slightly different context, it could be asking about sources of goldenrod ‘goldenrod honey’, in which case the answer is either the plants, or bees, or companies that sell foodstuffs like honey.)
My impression is that the wording of the question involves some sort of semantic reversal involving the noun sources, but I don’t see how to reformulate the question so that it asks something reasonable and could have a useful answer.
