25. 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. Eke or Carina is going to be the new dance squad captain.

The sentence that contains an error in subject-verb agreement is: **Each volunteer and staff member need to arrive at the scheduled time.** **Explanation:** - **Subject:** "Each volunteer and staff member" - The word "each" is a distributive pronoun that is singular. When "each" is used with "and," it still treats the subject as singular because "each" emphasizes individuality. - **Verb:** The correct verb form should be **"needs"** instead of **"need"** to agree with the singular subject. So, the corrected sentence should read: **"Each volunteer and staff member needs to arrive at the scheduled time."** All other sentences correctly match their subjects with the appropriate verb forms. **Answer:** Each volunteer and staff member need to arrive at the scheduled time.
