The great inventor Thomas Edison received more than one thousand patents during his career and made a large contribution to how we live today. For example, in 1877, after discovering a way to record sound, Edison introduced the phonograph. In 1893 he invented the first motion-picture camera. Eight years before inventing the phonograph, Edison received his first patent for a vote recorder, which was intended to help record legislative votes quickly. The Innovation he is most known for is the electric light bulb. He filed a patent for his light bulb in 1879. Though others contributed to the invention of the light bulb, Edison's work made this invention a long-lasting, practical household item.

How did Chief Justice Marshall contribute to the U.S. government system of checks and balances?
- A. by establishing the Supreme Court's power to check Congress
- B. by creating the power to remove the president from office
- C. by expanding the president's power to check Congress
- D. by giving the Supreme Court the power to control itself
Correct Answer & Rationale
Correct Answer: A
Chief Justice Marshall played a pivotal role in defining the Supreme Court's authority, notably through the landmark case Marbury v. Madison, which established the principle of judicial review. This empowered the Court to invalidate laws passed by Congress that it deemed unconstitutional, effectively allowing it to check legislative power. Option B is incorrect as the power to remove a president lies with Congress through impeachment, not the Supreme Court. Option C misrepresents Marshall's contributions, as he did not expand presidential power but rather clarified judicial authority. Option D is also inaccurate; the Supreme Court does not have self-regulating powers but operates within the framework of checks and balances.

Which statement is supported by both the table and the map?
- A. Differences in the total populations of the states led to political differences between the North and the South.
- B. Differences among the economies of the states contributed to political differences between the North and the South.
- C. Political differences between the North and the South reflected differences in education among the states.
- D. Political differences between the North and the South reflected differences in the standards of living in the states.
Correct Answer & Rationale
Correct Answer: B
Option B is supported by both the table and the map, as they illustrate how varying economic structures—such as agriculture in the South versus industrialization in the North—contributed to distinct political ideologies and policies. Option A incorrectly attributes political differences solely to population size, overlooking the economic factors at play. Option C suggests education differences as the main cause, which is not evident in the provided data. Option D implies that living standards were the primary influence, but the economic context is more directly linked to the political divide. Thus, B effectively encapsulates the relationship between economy and political differences.
