Answer to Question 1

Answer: D

Answer to Question 2

Answer: If the igneous structure is small (e.g. a dike), then the aureole will also be small, only a few centimeters in thickness. However, larger igneous bodies have more heat that they will release over a longer period of time. This means that the aureole will be more extensive (several kilometers for those around batholiths) and have zones of metamorphism.
