Dr. Sheldrake, the biologist who designed this study, believes that the results are...................(satisfying-convincing-concluding-persuading) enough to find out through further experiments precisely how the staring effect might actually come about.

I think that both satisfying and convincing sound good, but I have to choose just one and I'd say that satisfying is much better. Obviously, the book I took the text from suggests convincing. What do you think about it?
