Great question. When reading RC passages, it's always a good idea to silently force yourself to think about what the main point of the passage was as soon as you're finished reading. These main point/primary purpose questions are frequently asked, so having a general understanding of the main point will help you out a ton.
The question stem says, "The passage as a whole can most accurately be described as..."
In the passage, the author discusses problems that are associated with the constitutional reforms that are geared toward protecting the rights of aboriginal people. The author provides two examples of situations showing the Canadian courts' difficulties in interpreting the constitutional reforms to demonstrate how the very general language that is included in these reforms has led to inconsistencies in the protection of aboriginal rights.
In looking at the answer choices, (C) says, "an examination of problems associated with efforts to protect certain rights," and this matches up very well with our analysis of the primary purpose of the passage. (C) says that the author is looking at problems associated with efforts to protect certain rights, and this is exactly what we had said the other was focused on doing. This is our answer choice.
