lakes.txt
is indeed not a command and bash tells you so. Did you expect something else to happen? If so what?
Also, is the "-"
-character at the end of your first command supposed to have some effect? Why is it there?
did u follow the instruction? it state there need to put “-” in the command line.

Do you mean this?
cat lakes.txt | sort > sorted-lakes.txt
That’s part of the file name.
As it so happens it is allowed, from sort
's manpage:
With no FILE, or when FILE is -, read standard input.
But it’s optional, and I think it should rather be written in this order:
cat lakes.txt | sort - > sorted
But since reading from stdin is common behaviour for that kind of command, I find it a bit peculiar to add it, it might be there for compatibility or something like that.
But better yet is to write:
sort lakes.txt > sorted
