yes, "confere" (it maches). it is used when you compare two things, like who was invited for the party, the things you bought at the market match to your list... "this dress does not match to my shoes" = esse vestido não combina com meus sapatos. Match the columns = Marque/Ligue as colunas.
Ugh, hover-over hints are so wrong here. I wish they would catch up on these, do they even have anyone checking these, or is there a huge backlog? I've reported wrong or misleading hover-over hints in both Spanish and Portuguese and come back to the exercises months later to find them still not corrected. By contrast, when I suggest new translations they're often accepted in a matter of weeks.
This makes me wonder if there's a problem in the produced, or if they are understaffed when it comes to reviewing the suggestions for hover-over hints.
