Final answer:
Detroit is credited with numerous innovations in the automotive industry, including advancements related to the electrical starter. The alternating current allowed for the transmission of electricity over longer distances, and the electrification of workplaces increased production capacity. Additionally, not all the listed inventions were successful during the early industrial revolution, with frozen foods not yet commercially viable.
Step-by-step explanation:
The electrical starter is indeed a significant innovation attributed to the ingenuity of Detroit's automotive industry. As part of the automotive revolution, Detroit has been a center for technological advancements in vehicle manufacturing. It's important to note that while Detroit is widely recognized for its contributions to the automotive industry, the electrical starter, specifically, was invented by Charles Kettering and first implemented by Cadillac in 1912, not in Detroit itself but certainly an impact of the industry centered there. This innovation greatly enhanced the convenience and safety of operating automobiles, replacing the manual crank starters that were common at the time.
In relation to the other questions: alternating current (AC) power was advantageous because it allowed for electrical transmission over longer distances (C). If you drop a bar magnet through a copper tube, it indeed induces an electric current in the tube, demonstrating electromagnetic induction (b. true). Electrifying the workplace allowed factories to operate longer hours, contributing to an increase in production and urban workforce (b). The market revolution did bring many social and economic changes to the United States (a. True). High-voltage wires, while supported by insulators, are typically not wrapped in insulating material due to high operating temperatures and other practical considerations (b. false).
Regarding successful inventions of the era, frozen foods were not yet a commercial success in the time of the early industrial revolution, which accounts for the correct answer (C).
