Which should be added after sentence 6 to most effectively move the plot forward?
O The excitement of my new job started to wane, and I
began to reconsider if this was truly how I wanted to
spend my summer.
O Once I arrived, I quickly learned that my job would
also entail wiping tables, mopping floors, and
washing dishes.
I gulped down my food, grabbed my bus card, and
pecked my mother on the cheek as I raced out the
door.
O As I think back on my first job, I remember the many
mistakes I made and the important lessons I learned.

This question is incomplete because the sentence or excerpt is not given; here is the missing section:

Read the paragraph from a personal narrative.

1. It may have seemed like an ordinary day to everyone else, but to me, it couldn't have been further from it. 2, Today was my first day working as a waitress at Pete's Pizza Haven, and I could not have been more excited. 3. In fact, I was so excited that I rushed to get ready much faster than I typically do. 4. "I'm ready to go!" I shouted, bouncing down the stairs and flying into the kitchen, where my mom was making breakfast. 5. "I have so much to learn and don't want to be late," I declared for emphasis. 6. My mom just grinned and placed a steaming plate of eggs before me.  

The answer to this question is "I gulped down my food, grabbed my bus card, and pecked my mother on the cheek as I raced out the door".

Explanation:

Moving the plot forward implies adding information or actions that make the story advance. This includes introduce/develop a conflict or add actions, dialogues, descriptions, etc. that are meaningful in the story. Moreover, to move the plot forward the new elements need to continue previous elements.

In the narrative presented, the first six sentences describe the emotions and actions of the main character as she prepares for her first day of work. In the sixth sentence, the mother of the character offers her breakfast as she is about to leave. In this context, a detail that moves the plot forward is "I gulped down my food, grabbed my bus card..." because this continues with the sequence of actions previously describe but adds a relevant detail. Also, this immediately moves the character outside her home, which can be used to introduce new characters, a new setting (the pizzeria), and even conflicts.

i think it is b. hope this !
