Ignacio's grandmother is becoming old and trail. Which describes a technology that can help her stay in her home instead of moving to a nursing home?
O a technology-enhanced refrigerator that tells her when she is out of milk
O a medical-alert bracelet that informs first responders of a fall or an emergency
O a wheelchair that is equipped with a motor and power steering
O a fitness tracker that keeps a record of how much sleep she gets each night

a medical-alert bracelet that informs first responders of a fall or an emergency.

Explanation:

we can rule the others out because a refrigerator isn't going to help her from the nursing home, a wheelchair is helpful but the fact that they mentioned power steering doesn't fit well with this question, and a fitness tracker is good for health purposes but won't get her help.

i am sorry if my explanation doesn't make sense, but i am sure this is the right answer!

no because dogs are cats the product you bought is meant for cats xd
