Final answer:
A reasonable modification for Matilda could be installing Braille signage and accessible facilities like ramps or elevators, as required by the ADA, which prohibits discrimination against individuals with disabilities.
Step-by-step explanation:
An example of a reasonable modification that Matilda could request, being blind and using a wheelchair, would be the installation of a Braille signage and accessible facilities such as ramps or elevators at her workplace or school. These modifications would assist Matilda in navigating and accessing different areas that may otherwise be inaccessible due to her disabilities. The Americans with Disabilities Act (ADA) prohibits discrimination against those with disabilities and requires reasonable accommodations for them on the job, ensuring equal opportunities and inclusion in society.
