A passage is given below followed by several conclusions which can be drawn from the facts stated in the passages. You have to examine each inference separately in the context of the passage, decide upon its truth or falsity, and choose the conclusion that best supports the passage. 

It was in Germany and France that the first successful attempts were made to produce an internal-combustion engine drive by petrol. In England people were strangely timid about horseless vehicles. English inventors were handicapped by a quaint old law that forbade any such vehicle to attain a greater speed than four miles an hour, and compelled each one to be preceded by a man carrying a red flag. This law was not repealed until 1896. The earliest motor cars were looked upon as mere jokes, or rather dangerous playthings, by everyone except their inventors. Some of them were single-seaters, others would carry two or even three people, but all were noisy , clumsy, queer-looking things. When in 1888, Carl Benz, a German produced a three-wheeled, internal-combustion car, a great forward stride had been made. Another German, whose name, Daimler, is often seen on motor cars to this day, was experimenting about the same time, and testing a petrol driven engine. it is easy to understand hos the introduction of the petrol-driven engine revolutionized road transport throughout the world.  Until then the necessary power to push a vehicle along could not be obtained without the tanks, boilers and furnaces of the steam engine. 

The passage, if true, is best supported by which of the following conclusions?
