X. ответьте на вопросы в соответствии с содержанием текста. the materials used in car constructionthe bodies of the first passenger and freight cars were manufactured of wood. they were not strong enough and could not ensure the safe travel for passengers. moreover, being heated with coal-burning stoves, the carriages were often set on fire.the search for strength and safety led to all-metal cars. at first steel replaced wood in car construction. being much stronger that the conventional wooden cars the steel cars contributed a great deal to increased safety and could provide a greater carrying and seating capacity. however, steel has two drawbacks as the material of construction for cars: steel is heavy and it rusts. steel rusts so easily if it is not protected by paint and a steel car will rust away much quicker than an unpainted wooden car. to get away with these two disadvantages of ordinary steel modern cars are manufactured with bodies made of alloy steel and aluminum. the application of aluminum and its alloys to rolling stock construction is sure to be of great economic importance because of the advantages these materials offer as compared with steel. aluminum is a light weight metal, and it possesses good anti-corrosive properties. so its application results in considerable decrease of the rolling stock maintenance costs.1) what did the search for strength and safety lead to? 2) what cars replaced the conventional wooden cars? 3) what drawbacks does steel have? 4) what is done to get away with these drawbacks? 5) what are the advantages of aluminum?
