Q8

[ucsc24]

I was down to answer choices B)progressive and C)incomplete. I ended up choosing B because they are doing further research.

Is the answer progressive too strong, as that would mean that they are making ground and finding things out, which may not be true...

Thanks for the help

Good question. I agree that (B) is tempting here.

If we check out the last paragraph, there is no question that the author believes the research is incomplete. That's clear. "Progressive" is murkier. It means progress is being made. Is it?

Well, it is in the sense that the research on birds is leading to findings that could be useful to humans. But what really counts as "progressive?" Does this sole piece of evidence on birds? If we didn't have (C), we could make an argument for (B). But since (C) is there and unquestionably true, go for it.
