I have a genuine problem. A compound predicate has one subject and two or more verbs. This is the guideline I am following.
Compound Predicate takes no comma when there are two verbs:
- Michael dribbled across three defenders and passed the ball to his wide-open teammate.
Compound Sentence takes a comma and a conjunction:
- Michael dribbled across three defenders, and he passed the ball to his wide-open teammate.
This is the sentence I am having issues with:
Main Sentence: A. To qualify for fishing benefits, self-employed fishers must have paid premiums during their qualifying period and, depending on the regional unemployment rate, they must have earned between $2,500 and $4,200 in insurable earnings from fishing activities.
Repeating "they must have" requires I put a comma before "and" to make it a compound sentence. But then there are too many commas around "and".
If I reduce the verbiage, it should have the following form:
B. To qualify for benefits, workers must have paid premiums and earned between $2,500 and $4,200. (Compound predicate)
But if I wrote it as a compound sentence, it would include the comma before the conjunction.
C. To qualify for benefits, workers must have paid premiums, and they must have earned between $2,500 and $4,200. (Compound sentence)
Given there is this information after and "depending on the regional unemployment rate" that needs to be set of by a pair of commas, I felt that repeating "they must have" before earned made it easier to read. But then grammar requires me to put a comma before "and" (as is the case for a compound sentence with a coordinating conjunction).
How to punctuate sentence A ? Should I omit "they"?
Please, don't close this. I have done a lot of research in ELU and ELL, but I did not find anything similar. While there are simple examples that talk about the rules of compound predicates, there isn't any that deals with complex structures like the one above.
