Hey Forum,
I'm just getting started with Swift and I've been using Apple's "AP Computer Science Principles with Swift" book. Its been going great but I think I'm stuck here.
I thought I understood the initial exercise but I've become a little confused with the "experiment." I'm not sure what it wants me to do.
Would anyone care to paraphrase or show me an example? 
It seems it wants you to call the function a few times with different parameters, and save the result into variables. Probably to familiarize yourself with the function call syntax.
I think it’s asking you to write several lines like the following around line 20:
let anotherSentence = myFavorite(type: "programming language", exact: "Swift")
let yetAnotherSentence = myFavorite(type: "bird", exact: "the swift")
Swift is a bird, hmm, never know that 
Ah! Thank you.
I think I was overcomplicating it for myself and thought it was asking me to create a function that would fill in "exact" based on what I set the value of "type".
Appreciate the response.
