choosing a topic sentence and concluding sentence\nrobots can already clean floors and windows. there are soccer - playing robots and robots that do factory work that people used to do. robot arms can even build things and make repairs in space. we can use computer software to communicate with robots and give them commands. they can even respond to our requests.\nwhich topic sentence should be added to the paragraph?\nrobots repair things that are built by people.\nrobots are used in most households.\nrobots can function in many useful ways.

Answer

Brief Explanations:

The paragraph lists various useful functions of robots like cleaning, factory - work, space - repairs, and communication. The topic sentence should summarize these diverse functions. "Robots repair things that are built by people" is too narrow, and "Robots are used in most households" is not supported as the paragraph mentions more than just household use. "Robots can function in many useful ways" best sums up the content.

Answer:

Robots can function in many useful ways.
