Answer:
Most jobs now require computer skills, but the digital revolution has not improved our quality of life. Since a desktop computer, complete with headphones for sound-based functions, exists in every office, work should be simpler. However, neither increased efficiency nor improved employee morale has resulted from our switch from paper to computers. Indeed, each worker’s tasks have become more complex. In the past, for example, one invoice or two purchase orders were needed to complete a request for supplies. The process, including online confirmation, now requires five separate documents. The result of this unnecessary complication, not surprisingly, is frustration and curses. Everyone, including the supervisors, is fed up with the extra work. When our division implements a new computer system next month, I expect at least two of my co-workers to quit. Fifteen hours of training are needed to learn the new system, and that is more time than any of us has to waste.
Step-by-step explanation:
According to what you've written in the question, there are approximately 10 errors in the passage. I was able to find nine. Notice that, in the original passage, the verbs were not agreeing with the subjects properly. In the passage I posted above, they have already been corrected.
They are as follows:
1. a desktop computer... exist --> exists (singular subject, singular verb)
2.neither increased efficiency nor improved employee morale have --> has (subjects with "neither... nor" need a singular verb)
3. tasks has --> have (plural subject, plural verb)
4. one invoice or two purchase orders was --> were (when the subject has "or", the verb agrees with the noun closest to it)
5. the process... require --> requires (singular subject, singular verb)
6. the result... are --> is (singular subject, singular verb)
7. everyone... are --> is (singular subject, singular verb)
8. our division implement --> implements (singular subject, singular verb)
9. any of us have --> has (the verb agrees with "any", not "us")
