I need to reconstruct the following sentence in another way: "It activates the potential of the crowd to help..." Suggestions please!
I understand that phrase "activates the potential" is the issue, but it's not because it's a terrible phrase. It's just an uncommon way of writing, since "potential" typically doesn't act as the object or target of an action. But your phrasing is neither non-grammatical nor syntactically flawed, so you could leave it as it is. You could replace the phrase with a word like encourages, allows, permits, or enables.
"activates the potential" is pretty much just saying that that, in one way or another, the crowd is now willing to provide help. So with that being said (and without knowing what 'it' is). . .
It causes the crowd to help... It causes the crowd to provide their support... It makes the crowd help... (etc....)
In the three sentences I provide, there is no need to mention 'potential', because the action of helping makes clear the potential already existed/exists (otherwise they would not be able to perform the action). The original sentence just seams like some strange and unnecessary way of using synonyms.
