Answer to Question 1

ANS: C
Knowledge discovery and data mining (KDDM) makes use of specialized analytic methods, characteristically machine learning, to identify patterns in a semi-automated fashion.

Answer to Question 2

ANS: A, B, C, D, F
The knowledge transformation process in the STAR Model occurs at five points, which can be conceptualized as a five-point star. These five points include discovery research, evidence summary, translation to guidelines, practice integration, and evaluation of process and outcomes. Testing the hypothesis is not a specific point in the STAR Model.
