What is your answer?

and why are you mixing dashes and commas to separate the same clause?

oobleck is right. You should be separating that non-essential clause with two commas, not with any hyphens. Do you know the difference between hyphens and dashes? Do you know where the TWO commas belong?

Tellers,had run

The correct phrase to use in this sentence is "tellers ran". Here's how you can determine the correct answer:

1. Identify the subject: In this sentence, the subject is "tellers."

2. Determine the verb: The verb is the action performed by the subject. In this case, the verb is "ran."

3. Combine the subject and the verb: The subject "tellers" and the verb "ran" should be combined to form the phrase "tellers ran."

Remember that in English, an action verb like "ran" is typically used without any punctuation or special characters between the subject and the verb. So, options like "tellers:ran," "tellers, had run," "tellers-ran," or "tellers' ran" are not correct in this context.

It's important to pay attention to grammar rules and sentence structure to ensure clear and accurate communication.
