Questions & Answers about Wir haben eine Umfrage über den neuen Snack gemacht.
Why is it über den (accusative) and not dative here? Doesn't über sometimes take the dative?
Yes, über is a two-way preposition. When talking about physical location ("above"), it can take the dative or accusative depending on movement. But when über means "about" a topic, it always takes the accusative case. Since Snack is a masculine noun (der Snack), the article changes to den.
Why does the adjective get an -en ending in den neuen Snack?
This is an example of weak adjective declension. Because we already have the definite article den doing the heavy lifting by showing us that the noun is masculine and in the accusative case, the adjective just takes the standard weak ending -en.
Is machen the best verb to use with Umfrage (survey)?
machen is very common and perfectly natural in everyday conversation. If you want to sound more formal or professional, like in a business setting, you can use the separable verb durchführen (to conduct). In that case, you would say Wir haben eine Umfrage durchgeführt.
