Final answer:
The correct level when a person needs a device, more time, and safety precautions for toileting tasks is Device assistance. Sidewalk ramps and Braille signs are both accommodations required by the ADA and forms of accessibility for people with disabilities.
Step-by-step explanation:
For toileting tasks, when a person requires a device, more time, and safety precautions, the level of assistance is indicated as Device assistance. This implies that the person is not fully independent but doesn't necessarily require another person for supervision or aid. Instead, they may need special equipment or modifications to perform the task safely and might need extra time due to these additional requirements or mobility limitations.
Sidewalk ramps and Braille signs are accommodations required by the Americans with Disabilities Act (ADA) and are also considered forms of accessibility for people with disabilities. These features are designed to ensure that individuals with disabilities can access public spaces and receive information in a manner that accommodates their needs. Therefore, the correct answer to the question would be d. both b and c.
