Which sentence contains an error in subject-verb agreement? some of her friends and family members are coming over for dinner. each volunteer and staff member need to arrive at the scheduled time. july and august are the warmest months of the year. elke or carina is going to be the new dance squad captain.

Each volunteer and staff member need to arrive at the scheduled time.

Explanation:

The adjective each is used before a singular countable noun and, therefore, the verb should be in singular form, too.

So the sentence should be written as "Each volunteer and staff member needs to arrive at the scheduled time."

different strategies reach different people based on their ability to understand the material. (from personal experience) when writing an argumentative essay write explaining the subject as though your audience never heard of it before and it is just being introduced, then explain why other people hate it also, afterward you would explain why that would be wrong. i hope that : )
