 A.

We had been walking non-stop for five hours and were nearing the top of the mountain

but I couldn't keep at it any longer. I had to stop and rest.

I was too tired to continue.

B.

Everyone in the office was busy working on the report for the big meeting.

The boss told us to keep at it until the job was finished.

We didn't leave the office until 11 p.m.
