Group of answer choices

If the Supreme Court did not overturn some laws, state governments would challenge unpopular laws on their own.

Supreme Court justices are less subject to popular pressure than others since they are appointed for life.

It is the role of the courts to interpret and apply the law, and the Constitution is the highest law.

The Supreme Court is more neutral than either Congress or the President.

Answers

Answer:

I'm pretty sure the answer is... It is the role of the courts to interpret and apply the law, and the Constitution is the highest law. This all ties back to judicial review where the courts can label something unconstitutional also ties back to checks and balances where each branch has a specific power and job.

How do Phelan's beliefs about Chainese immigrants demonstrate nativism?​

Answers

Explanation:  The Chinese Exclusion Act was passed in 1882, and again in 1892.] The Exclusion Acts then passed were limited to ten years’ duration. In May next the latest act will expire by limitation, and Congress will be asked to renew it, because, until now, Chinese exclusion has been regarded in diplomatic circles and elsewhere as the settled policy of the country. Has there been any change in the nature of the evil, or in the sentiments of the people? Certainly not on the Pacific Coast, where the lapse of time has made still more evident the non-assimilative character of the Chinese and their undesirability as citizens.

Authoritarianism is a term used by political scientists to characterize a kind of government that prioritizes order and control over individual freedom. The person in charge of an authoritarian state is typically a dictator.
