Read the following paragraphs, without using a dictionary. After each paragraph, choose the sentence that best expresses the main idea.

B. Train travel used to be simply a means of getting from one place to another. Now, for people with money, it can also offer education or adventure. The Trans-Siberian Special, for example, is a tour that runs from Mongolia to Moscow. The train stops in big cities and small villages so that passengers can go sightseeing, and there is a daily lecture on board the train, in which everyone learns about history and culture. For people who are looking for fun and adventure, there are the Murder Mystery Trains of Western Australia. These trips interest people who love Sherlock Holmes, Hercule Poirot, and Miss Marple. They are for people who have always secretly dreamed of being a private eye and solving mysteries. The passengers on board have the opportunity to solve a murder mystery right there on the train. During the train ride, for instance, there might be a gunshot; soon everyone learns that there has been a "murder," and they spend the rest of the trip playing detective. They track down clues, exchange this information and their opinions, and solve the whodunit by the time the train has pulled into the station. Of course, no real crime takes place. The "murderer" and several passengers are actually actors. The trip is a very creative game.
