The following article provides detailed explanations for each answer to the multiple-choice questions from the passage on electric cars.
Question 1: Why did electric cars gain popularity in the late 1800s?
Answer: B. They were simple, quiet, and did not emit harmful gases.
Electric cars in the late 1800s became popular because they addressed many of the inconveniences associated with early gasoline-powered cars. Gasoline vehicles were noisy, required hand-cranking to start, and produced harmful exhaust gases. In contrast, electric cars were easy to operate, much quieter, and pollution-free, making them highly appealing, particularly for urban areas.
Question 2: Why was the EV1 discontinued, despite its success?
Answer: B. The oil industry allegedly pressured its discontinuation.
Although General Motors’ EV1 received a positive reception, its discontinuation was reportedly influenced by external factors such as the oil industry’s resistance and challenges in scaling battery production. Critics argue that the oil industry had an interest in maintaining the dominance of gasoline vehicles, which contributed to the decision to halt production.
Question 3: What feature of lithium-ion batteries made them revolutionary for electric cars?
Answer: B. They allow cars to travel hundreds of miles on a single charge.
Lithium-ion batteries revolutionized electric vehicles by providing high energy density and rechargeability. This innovation allowed EVs to cover hundreds of miles on a single charge, making them practical for daily use and long trips. Compared to older lead-acid batteries, lithium-ion batteries represented a significant leap in performance.
Question 4: Under what condition do electric vehicles have a significantly lower carbon footprint?
Answer: B. When they are powered by renewable energy sources.
While electric cars produce zero tailpipe emissions, their true environmental benefit depends on the energy source used to charge them. If EVs are powered by renewable energy, such as solar or wind power, their carbon footprint is greatly reduced compared to those charged using electricity generated from fossil fuels.
Question 5: What two factors have contributed to Norway’s leadership in electric vehicle adoption?
Answer: B. Its generous incentives and robust charging network.
Norway has led the world in EV adoption thanks to a combination of policies. Generous incentives, such as tax breaks and subsidies, reduce the cost of purchasing EVs, while a well-developed charging infrastructure ensures convenience for drivers. These factors have made electric cars a practical and affordable choice for Norwegians.
Question 6: What is a primary reason for “range anxiety”?
Answer: B. Fear of running out of battery power before finding a charging station.
Range anxiety refers to the fear that an electric vehicle’s battery will run out before the driver can locate a charging station. While EV ranges have improved significantly, the availability of charging stations, especially in rural areas, remains a concern for many potential buyers.
Question 7: Why is ultra-fast charging technology considered important for EVs?
Answer: C. It significantly decreases charging time, making EVs more convenient.
Ultra-fast charging technology can charge a car in minutes rather than hours, addressing one of the major barriers to EV adoption—long charging times. This technology improves the convenience of owning an electric vehicle, making it comparable to the quick refueling experience of gasoline-powered cars.
Question 8: What is one innovation that could make EVs more appealing in the future?
Answer: B. Wireless charging technology.
Wireless charging technology is an exciting innovation that could enhance the convenience of electric vehicles. By eliminating the need for plugging in, this technology could make EV charging as simple as parking the car over a charging pad, further encouraging adoption.
Question 9: What is one strategy being used to change consumer habits regarding EVs?
Answer: B. Running public education campaigns about EV benefits.
To address hesitation from consumers, public education campaigns aim to raise awareness about the benefits of EVs, including their environmental advantages and lower operating costs. These campaigns, combined with initiatives like trial programs, help build confidence and familiarity among potential buyers.
Question 10: What are three benefits of electric vehicles mentioned in the conclusion?
Answer: A. Reduced emissions, lower operating costs, and cutting-edge technology.
The conclusion highlights three key benefits of electric vehicles: their ability to reduce emissions (especially tailpipe emissions), their lower cost of operation compared to gasoline-powered cars, and their integration of advanced technologies such as autonomous driving and wireless charging. These advantages position EVs as a sustainable and innovative choice for the future.
