Difference in connotation between "a statement" vs "a statement to make"
Solution 1:
I find that the difference between:
(1) That sounds like a bold statement.
and
(2) That sounds like a bold statement to make.
lies in the fact that in (1) the boldness is attributed to the statement itself, while in (2) it is attributed to the making of the statement. (1) is therefore more impersonal than (2). Even though the maker of the statement is not mentioned in (2), there is an implicit reference to him/her as the doer of the action. It can thus be understood that it was bold of him/her to make the statement.
