How can you make the fragment "_______________ as she watched me from the kitchen window" into a complete sentence?

To turn the fragment "_______________ as she watched me from the kitchen window" into a complete sentence, it is essential to provide a main clause that connects logically to the action of watching. The choice that fits this requirement is the one that adds a relevant action occurring simultaneously with her observation.

The chosen response emphasizes an action directly related to the observation: running around outside. This creates a vivid picture, illustrating the dynamic relationship between the person watching and the person being watched, thus forming a complete thought. The use of the phrase "as fast as I could" adds urgency and context to the action, enhancing the imagery of the scene.

In contrast, the other options, while they describe various actions, do not establish a clear relationship with the act of watching from the kitchen window. They would not effectively connect to the fragment, thereby failing to make it a cohesive and complete sentence.
