"To badanie dało nam dużo wniosków."

Translation: This research gave us a lot of conclusions.

"This research gave us a lot of conclusions" is awkward in English. "This research gave us a lot of results" would be the way it would be said and written in English. Alternately, "This research drew a lot of conclusions."
