These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. 1. A few countries already use powerful electromagnets to build high-speed trains. P. Since maglev trains float in the air, there is no friction between the train and the track. Q. Maglev trains work on the principles of magnetism and float over a guideway. R. Maglev is the shortened form of magnetic levitation. S. These trains are called maglev trains. 6. This lack of friction and the aerodynamic design of these trains allow them to reach speeds of over 500 kilometers per hour.?
