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.
Which technology mentioned in the passage was the first one invented by Edison?
- A. vote recorder
- B. motion-picture camera
- C. electric light bulb
- D. phonograph
Correct Answer & Rationale
Correct Answer: A
The vote recorder was the first technology invented by Edison, designed to streamline the voting process. This innovation predates his more famous inventions. The motion-picture camera (B) and electric light bulb (C) came later, showcasing Edison's evolution as an inventor. The phonograph (D), although significant in audio technology, was also developed after the vote recorder. Understanding the chronological order of these inventions highlights Edison's early contributions to technology and their impact on society.

Which feature of the U.S. system of government did de Tocqueville believe might cause conflict in society?
- A. The majority is able to achieve special rights.
- B. The minority is able to block popular legislation.
- C. Legislators must represent minority interests.
- D. Legislators sometimes act against majority rule.
Correct Answer & Rationale
Correct Answer: A
De Tocqueville observed that when the majority in a democracy can impose its will, it might lead to the oppression of minority groups, creating societal conflict. This reflects his concern about "tyranny of the majority," where the dominant group's interests overshadow the rights of others. Option B is incorrect because while minorities can influence legislation, de Tocqueville focused more on majority power. Option C misrepresents his views; he acknowledged the importance of minority representation but did not see it as a source of conflict. Option D is also inaccurate, as de Tocqueville emphasized the potential for the majority to dominate rather than legislators opposing the majority.

How does the U.S. Supreme Court's ruling differ from Justice Murphy's dissent?
- A. Only Justice Murphy's dissent acknowledged the dangers to the United States of having citizens from foreign lands.
- B. Only the Court's ruling acknowledged that the actions of fearful U.S. authorities can endanger the civil rights of citizens.
- C. Only the Court's ruling contended that Korematsu was ordered held in an internment camp because he was disloyal to the United States during time of war.
- D. Only Justice Murphy's dissent contended that U.S. internment camps were a clear-cut example of racial prejudice.
Correct Answer & Rationale
Correct Answer: D
Justice Murphy's dissent emphasized that the internment camps represented blatant racial prejudice, highlighting the unjust targeting of Japanese Americans based solely on their ethnicity. This perspective contrasts sharply with the majority opinion, which focused on national security concerns without addressing the racial implications. Option A is incorrect as both perspectives recognize the potential dangers of foreign nationals, albeit in different contexts. Option B misrepresents the majority's stance, which did not explicitly acknowledge civil rights violations. Option C inaccurately simplifies the Court's ruling, which did not solely attribute internment to disloyalty.

What was the mean population across the British American colonies in 1700?
- A. 56,000
- B. 21,000
- C. 6,000
- D. 16,000
Correct Answer & Rationale
Correct Answer: D
In 1700, the mean population across the British American colonies was approximately 16,000. This figure reflects the early colonial growth and settlement patterns during that period. Option A (56,000) overestimates the population, as it does not account for the smaller settlements and rural areas that characterized the colonies at that time. Option B (21,000) is also too high, misrepresenting the demographic data available for the early 18th century. Option C (6,000) significantly underestimates the population, ignoring the established colonies with growing communities. Thus, D accurately represents the mean population based on historical records.

- B. The Magna Carta forced the nobles to give up their feudal lands.
- C. The English Bill of Rights guaranteed suffrage to most male citizens.
- D. The Magna Carta forced the king to share his political power.
Correct Answer & Rationale
Correct Answer: D
The correct choice, D, highlights the Magna Carta's pivotal role in limiting the king's absolute power and initiating the concept of shared governance. This foundational document established that the monarch must consult nobles before making decisions, laying the groundwork for parliamentary democracy. Option A is incorrect as the English Bill of Rights actually limited the king's power over Parliament, not enhanced it. Option B misrepresents the Magna Carta's purpose; it did not force nobles to relinquish their lands, but rather addressed their grievances against the king. Option C is also inaccurate, as the English Bill of Rights did not guarantee suffrage but focused on limiting royal authority and protecting certain rights.
