Question What is the main purpose of the passage?
To describe competition in the computer industry
To offer two views of a controversial figure
To caution entrepreneurs about the need to patent their products
O To provide information about an invention

To provide information about an invention

Explanation:

The passage contains details that are meant to provide information about an invention which is the computer mouse.

It tells when it was made and who made it as well as the first design it was made in and how this relates to its design now which is all information about the invention.

Option A is wrong because competition is not alluded to. B is wrong because the passage does not allude to any two sides of the inventor and option C is wrong because the product was indeed patented but the patent expired.
