Answer:
B.
Roosevelt successfully added more Supreme Court justices to the bench that supported his policies.
Explanation:
During the time of Franklin Roosevelt as the President of the United States, when Supreme Court struck down several key pieces of his New Deal legislation, after two years, he first proposed age limit for Justices, such that whenever a Justice clock 70 years, and 6 months old, and who had served 10 years or more should be retired.
However, should a Justice refuse to retire, Roosevelt added More Supreme Court Justices to the bench, with equal voting right. This was later termed as "Court parking".
Hence, the right answer is, Roosevelt successfully added more Supreme Court justices to the bench that supported his policies.
The correct answer is A) so that no single branch of the government would gain too much power.
<em>The concepts of checks and balances were established by the authors of the Constitution so that no single branch of the government would gain too much power.
</em>
This concept is a valuable precept because with the checks and balances system, it can pervent wrongdoings from the other parts of the government and the exercise of power is equally divided. In the United States, the Constitution acknowledges three branches: the executive, that in the presidency of the U.S.; the legislative, that is the House of Representatives and the Senate; and finally, the Judiciary, that is the Supreme Court.
