Hello. First-time poster. Pleased to be here.

I have a question about the usage of "information" in the following:

1) This information is correct.
2) That information is correct.
3) These information is correct.
4) Those information is correct.

I was told that 1 & 2 are the only correct ways to talk about "information" -- as well as other mass nouns, such as "furniture" and "data."

When I asked my friends why 3 & 4 were incorrect, they just said that it "sounds wrong."

"These/those data..." also sounded incorrrect to them. They feel that since "information" and "data" are already plural, they just need either "this" or "that."

Are they right? I am very adamant about thinking that "These/Those information..." is grammatically correct.
