I have checked this site.
- We use this or that to refer to something with special emphasis – indicating an interesting new fact has been mentioned.
- We use this or that to refer to a new topic, often the last thing mentioned. The reference could be a word, phrase or clause.
Are the uses of "this" and "that" below both grammatical? I think "that" also can be used in the sentences. I'd value your opinions.
Could any native speaker please answer this?
