Robots have been around since the 3rd century BC. At that time, they were mainly invented as toys to amuse the king or emperor. Now, robots help life on Earth by... I. gathering information from areas that humans cannot easily study. II. performing repetitive jobs more quickly and accurately than humans. III. making it possible for humans to be completely unnecessary in factories and research facilities. A. II and III only B. I and II only C. I and III only D. I, II, and III

The correct answer is

B. I and II only

Explanation:

The limitations of robots in factory and research include

1. Robots are capital intensive and require high cost to maintain while still being maintained by humans

2. Robots develop fault and require specific procedures to rectify the fault hance there is high potential for delays in factory production work.

3. When there is a cause for alteration of process or change in operation, the robot most likely will have to be changed as well whike the humans implement the change

4. In research, robots can not recognize unexpected variation indications and synthesis of ideas to explain observed anomalies like humans.

5. A robot does not increase in knowledge of an subject they work on whichose valuable insight is vital to research
