Not sure if you still need help but...

When the fly lands on Sally's hand, she will feel it with her sensory receptors in her skin. This will then lead to the sensory information of the fly touching her being transferred to the CNS (central nervous system) via sensory neurons. The CNS will then relay the message of moving the arm /hand to brush the fly (via the interneurons) to the motor neurons associated with the muslces in her arm. Once the motor neurons receive the message, they can then carry out the appropriate voluntary movement of Sally moving her arm to brush the fly away.

This is given that her brushing the fly away is not a reflex response.
I hope this helps
