Reese's use of illegal drugs limits her ability to walk properly. The elevator at her office was not working for many months, so Reese needed to climb two flights of stairs and had difficulty getting to her desk. She tried suing her company under the Americans with Disabilities Act, arguing that her company discriminates against individuals who cannot perform major life activities. Which of the following would weaken Reese's argument?
A) Reese is not a senior employee.B) The ADA prohibits discrimination only against workers who are over the age of 40.C) The ADA does not cover conditions of substance abuse.D) Reese is not pregnant.E) The ADA applies only to the decisions or actions of the government.

The purpose of the ADA (Americans with Disabilities Act) is to protect people with disabilities from abuses or discrimination. This includes the protection against discrimination at work in factors such as working conditions, hiring processes, etc. Additionally, this act protects almost all disabilities except by those related to conditions such as substance abuse or addictions. In this context, the ADA would not protect Reese because her disability is related to substance abuse, and therefore, this would weaken her argument.
