EV Charging Technology

Answer: B

Electric vehicles (EVs) are becoming increasingly popular, but one major obstacle remains: charging time. While gasoline cars can refuel in minutes, most EVs require hours to fully charge. A startup called ChargeNow has developed a new battery technology that promises 80% charge in just 10 minutes. If successful at scale, this technology could eliminate one of the primary barriers to widespread EV adoption.

According to the text, what is the main advantage of ChargeNow's new technology?

A. It makes electric vehicles less expensive
B. It significantly reduces charging time for electric vehicles ✓
C. It increases the range of electric vehicles
D. It eliminates the need for charging stations

Detailed Explanation

Choice B is correct. The text explicitly states that ChargeNow's technology "promises 80% charge in just 10 minutes," directly addressing the charging time problem.

Key Evidence:

• "one major obstacle remains: charging time"
• "80% charge in just 10 minutes"

Why others are wrong: A (cost), C (range), D (no charging) are not mentioned in the text.
