Language quiz

Here's the new quiz - and always remember, maybe nothing is wrong!

from a television commercial:

"If you don't absolutely love your new glasses, you can exchange them for another." - Lenscrafter

Here's the previous quiz:

From an entry in Wikipedia:

The Velikovsky/Ackerman catastrophism also reveals many facts still unknown in uniformitarian (academic) circles, concerning the other planets.

Remember: I'm looking for something grammatically wrong, not factually!

There's actually nothing wrong with this one, grammatically.

It's a bit awkwardly constructed, with that "concerning the other planets" hanging off at the end as it is; it's possible to read that as referring back to the "circles" rather than the "facts". (The comma makes that reading unlikely, however.) But stylistic awkwardness isn't the same thing as grammatical incorrectness, and this sentence is grammatically correct.

Having catastrophism revealing facts is semantically strange, perhaps, but, again, not grammatically incorrect.
