Final answer:
Exact answers for long-distance train travel distances and the number of states they pass through vary by route and country. For instance, certain Amtrak routes in the USA can extend over 1,300 miles and pass through up to 5 states, though this does not exactly match the provided answer options.
Step-by-step explanation:
The question regarding long-distance train travel does not specify a particular train or route; therefore, it's impossible to give an exact answer as it varies greatly depending on the country, rail network, and the specific routes of the trains in question. In the United States, for example, the Amtrak's Coast Starlight route travels approximately 1,377 miles and passes through 3 states, while the Amtrak's Texas Eagle journey can extend up to about 1,306 miles as it traverses 5 states. This does not match any of the options provided exactly but gives an idea of the sort of distances long-distance trains can cover and the number of states they can pass through. Long-distance trains are capable of traveling several hundred or even thousands of miles, and the number of states they pass through can be quite varied depending on the route's origin and destination.
