As I said, by the sounds of it, it’s an informal vote or an opinion poll, if you like, so poll votes and quora probably have nothing to do with it.
But if the committee is going to offer four options, they should have devised a way so people understood what their votes meant.
If it’s just a straw poll to reduce the options to a binary choice, to be decided in a formal setting, then they should have spelled that out.
