Ambiguity, literally

I attempted The Star's Word Puzzle Contest. Just complete the sentences and fill in the blanks with right letters; how hard can it be?

Oh yeah? Try this:

A trident is a spear that has three ___
Fill the blanks: P??N?S
Prongs or points?

Not that hard? How about this:

A new project sometimes ___ well as a result of good publicity
Fill in the blanks: ?OES
Goes or does?

Here comes the clincher:

An ___ proposal for solving a problem is no help at all
Fill in the blanks: IN?P?
Inapt or inept?
Note: Inapt = inept

You can't get any more ambiguous than that.
