As of 2023, Turkey has 1,015 kilometers of high-speed rail lines in operation and 614 kilometers under construction; in Germany, 1,630 kilometers are in operation with 3,262 kilometers under construction. In contrast, the United States has a relatively low amount of high-speed rail for its size: only 735 kilometers of high-speed rail in operation and 1,789 kilometers under construction. Many US transportation experts argue that this should change, claiming that high-speed rail is more cost-effective than highway systems are.

Which finding, if true, would most directly support the US transportation experts’ claim?

• A.

  In most locations in the US, increasing highway capacity is more expensive relative to the volume of traffic that can be accommodated than increasing high-speed rail capacity is.

• B.

  In much of the US, the existing rail infrastructure is so old that it would have to be replaced entirely in order to accommodate high-speed trains.

• C.

  Building successful high-speed rail infrastructure would require that the US government establish a fund to maintain the rail lines long-term.

• D.

  Unlike people in the United States, people in Turkey and Germany are less interested in traveling by highway than they are in traveling by high-speed rail.
