Explanation:

The problem is about the system of checks and balances in the US government, specifically related to the actions taken to address concerns about the Constitution. The options involve judicial review, branches' powers, etc. For question 6, the action to check the power of Congress (as per the passage about branches checking each other) would be the Supreme Court exercising judicial review (option 1). For question 7, Anti - Federalists opposed the Constitution because they thought the executive branch had no limits (option 3), as they were concerned about potential overreach without proper checks.

Answer:

Question 6: (1) exercising the power of judicial review
Question 7: (3) The executive branch had no limits on its authority
