Ford is testing the use of robots that assist in ergonomically difficult tasks. Workers on the production line often have to use heavy air$-$powered tools to complete their tasks, but the new robots can assist their human counterparts with these jobs. Ford's efforts show their concern for employees regarding:

a$.$ equality among humans and robots.

b$.$ occupational safety.

c$.$ use of technology.

d$.$ ethical decision making.

e$.$ innovative techniques.
