The Supreme Court will hear arguments about the use of public money for the private schooling of children with special needs. It’s interesting to note what’s not at issue: namely, that when a public school system is unable to provide an appropriate education, it is obligated to pay the costs of private school. Too bad poor children don’t have that unshakable right; if they did, there would be no controversy about the District program that gives vouchers to low-income children to attend private schools.
The case to be heard by the court hinges on whether parents have to enroll a child with special needs in public school before the child can attend private school at public expense. Special-education advocates say students shouldn’t have to waste time before being placed in a setting that best suits their needs, while school boards worry about a ruling that could amount to an unfettered fight to private schooling at public expense.

The first hotels were very different from today’s hotels. They were small inns built along the road. Later, as people began to travel by train, hotels were built in the centers of large cities. Usually located near railroad stations, these hotels were many stories tall and had hundreds of rooms.
Although trains were a popular means of travel for some time, automobiles slowly began to take their place. Automobile travel caused problems for city hotels, which did not have parking space for so many cars.
People who traveled by automobile needed a different kind of hotel. They needed places to stay that were near highways and had room to park. Motorists did not like to drive in heavy city traffic to reach a hotel. The answer to the motorists’ problems came when a new kind of hotel was built. These new buildings were called motels, a word made from the first part of MOTORIST and the last part of HOTELS.
Motels were much smaller than hotels.
A. they are losing their competition to motels
B. people need the materials to build small motels
C. it costs too much money to stay in a hotel
D. cities are usually short of land for building motels
