49. What is TRUE about the author’s test drive of one of the air-powered cars?
(A)The author drove the latest model of Nègre’s air-powered cars.
(B)The car had three wheels and was controlled by a steering wheel.
(C) The speed of the car was 25 miles per hour as its maximum.
(D) The site of the test drive was the parking lot of where the car was made.

 The version I drove was an early prototype, a three-wheeler with no bodywork, steered by a joystick. OK, it didn’t deliver the smoothly upholstered power so beloved by conventional car enthusiasts. And it possessed all the glamour of souped-up lawnmower. But it worked, easily reaching speeds above 25 mph in the limited space of the factory car park. For those who hope to get around in a very eco-friendly way without insisting on power and speed, I do see the future.

駕駛的版本是一個早期的原型車，一輛沒有車身的三輪車，由操縱桿操縱。 好吧，它沒有提供傳統汽車愛好者所鍾愛的平滑軟墊電源。 它擁有強化割草機的所有魅力。 但是它在工廠停車場的有限空間內很容易達到25英里/小時以上的速度。 對於那些希望以一種非常環保的方式繞行而不堅持力量和速度的人來說，我確實看到了未來。
