Why not “reveal“? It was put in the suggestions. To use “show“ strikes me as awkward since syntactically, that verb absolutely needs an object - either direct or indirect (what/to whom) - and neither is given in this example. (Sorry for waffling)
There is a direct object, "le joli sac violet". "reveal" is technically correct, but... What would it actually mean in this particular sentence? It sounds really weird to me.
By the way, the hints are for the whole course, and often they don't all apply to every sentence. As a general rule the top one will fit, though there are a few exceptions where the automatic ordering (which we can't control) messes up.
For a lot of sentences I'm in full agreement (there are some sentences where the female is better than the male though). Unfortunately, there's nothing we can do about what voices can say what sentences at this point.
Why is "We point out the lovely purple bag". not accepted? The sentence "Elle montre une mouche " is interpreted as she points out a fly.
Is "violet" really pronounced like "zhoh-lay"? That's what the speaker sounds like
