Please tell me the difference between dated and outdated, between well-off and rich and between prolong, delay and extend
1. It was a fashionable film years ago, but it looks ____ now. A. Dated B. outdated
I am very confused because both words mean old-fashion.
2. He may have a nice house, a nice car and be able to afford to go on nice holidays, but you couldn’t say he was ____ A. Well-off B. rich
Again, well-off and rich both mean wealthy.
3. The police asked the kidnappers to _____ the deadline by six hours A. Prolong B. lengthen C. extend
This time I don't know what to choose among these three words similar in meaning.
