I recently encountered a grammar problem as follows:
"I hope it'll rain tomorrow."
"From ( ) you've just said, maybe you don't want to go on the picnic."
Well, the answer is of course supposed to be (ii). However, one student thought it was (i). He gives this sentence:
From that that you've just said...
He claims that the first "that" indicates the entire sentence starting "I hope ..." and the second one works as a relative pronoun here. Omitting the second one, he got
From that you've just said...
What do you think about his claim? Both he and I know this sentence sounds unnatural, but at least from the grammatical viewpoint, we have no idea why it's not correct.
