Question

what is the purpose of the article \a technology revolution\?

to persuade people to take advantage of new technology
to entertain people with anecdotes about technologies of the past
to narrate how technology has influenced the life of the writer
to inform people about the changes in technology and its impact on our lives

Explanation:

Articles titled "A Technology Revolution" typically aim to inform readers. The first option ("persuade") implies a call - to - action which isn't indicated by the neutral title. The second option ("entertain with anecdotes") is too narrow as the title suggests a broader scope. The third option ("narrate writer's life") is also too limited. The fourth option ("inform about changes and impact") aligns with the general purpose of such an article title.

Answer:

to inform people about the changes in technology and its impact on our lives
