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 conclusion is best supported by information in the table and article?
- A. Individuals contributed a total amount of money equal to the total of all other sources of donations.
- B. Individuals contributing the smallest quantity of money insignificantly impact presidential campaigns.
- C. Individuals donated the greatest total amount although many contributions were relatively small.
- D. Individuals have more influence on the proposed policies of presidential candidates than groups do.
Correct Answer & Rationale
Correct Answer: C
Option C is supported by the data, indicating that while many individual contributions were small, they collectively formed the largest portion of total donations to presidential campaigns. This highlights the significant role individuals play despite the size of their contributions. Option A is incorrect as it suggests individuals’ contributions equaled all other sources, which is not supported by the data. Option B misrepresents the impact of smaller donations; even small contributions can collectively influence campaign funding significantly. Option D overstates individuals' influence on policy compared to groups, which often have more resources and organized lobbying power.
