The Bush administration is about to propose far-reaching new rules that would give people with disabilities greater access to tens of thousands of courtrooms, swimming pools, golf courses, stadiums, theaters, hotels and retail stores. The proposal would substantially update and rewrite federal standards for enforcement of the Americans With Disabilities Act, a landmark civil rights law passed with p bipartisan support in 1990. The new rules would set more stringent requirements in many areas and address some issues for the first time, in an effort to meet the needs of an aging population and growing numbers of disabled war veterans.

More than seven million businesses and all state and local government agencies would be affected. The proposal includes some exemptions for parts of existing buildings, but any new construction or renovations would have to comply. The new standards would affect everything from the location of light switches to the height of retail service counters, to the use of monkeys as "service animals" for people with disabilities, which would be forbidden’.

The White House approved the proposal in May after a five-month review. It is scheduled to be published in the Federal Register on Tuesday, with 60 days for public comment. After considering those comments, the government would issue final rules with the force of law. Already, the proposal is stirring concern. The United States Chamber of Commerce says it would be onerous and costly, while advocates for disabled Americans say it does not go far enough.

Since the disability law was signed by the first President Bush, advances in technology have made services more available to people with disabilities. But Justice Department officials said they were still receiving large numbers of complaints. In recent months, the federal government has settled lawsuits securing more seats for disabled fans at Madison Square Garden in New York and at the nation’s largest college football stadium, at the University of Michigan.

The Justice Department acknowledged that some of the changes would have significant costs. But over all, it said, the value of the public benefits, estimated at $ 54 billion, exceeds the expected costs of $ 23 billion. In an economic analysis of the proposed rules, the Justice Department said the need for an accessible environment was greater than ever because the Iraq war was "creating a new generation of young men and women with disabilities". John L. Wodatch, chief of the disability rights section of the Justice Department, said:"Disability is inherent in the human condition. The vast majority of individuals who are fortunate enough to reach an advanced age will benefit from the proposed requirements.

According to last paragraph, the proposed rules would()

A. be costly and impose pressure on the government

B. be profitable and bring interests to citizens

C. be beneficial to both the aged and the disabled

D. be a compensate to those Iraq war victims
