1. How did the Supreme Court gain the power of Judicial Review? ?

You will find a really succinct answer in your textbook. Go to the index (it's at the back of the book), and find the phrase "judicial review". Then go to the page it shows, and you will find the answer stating when they gained that power. This is the answer that the teacher really wants, not what somebody on Yahoo answers (no matter how accurate or intelligent the answer) posts.
