Original study is under paywall as usual, but how can we know they didn't guess the sugar water through other ways, like smell for example?

You remove the sugar water entirely and test which cards they go to when foraging. Similar to how you train any animal. You start with food rewards and praise, eventually they'll do it just for praise.
