Answer:
<em>Perseus</em> sneaks up to <em>Medusa</em>, the only Gorgon who is mortal. He raises his sword, taking aim by looking at the monster through the reflection in his shield, and chops off <em>Medusa's head</em>. As <em>Medusa's head</em> flies from her body, Pegasus, the winged horse, and Chysaor, a giant with a golden sword, jump out of her neck.
Hope this helps :)

Parallel structure refers to having the same
structure or parts of speech in the same sequence and function. In the sentence,
the parallel structure that needs to be paired with is “in a big city” which is
a prepositional phrase; so, the choice that has the same format is “in a
mountain cabin” which is also a prepositional phrase. “To go,” “staying,” and “being”
are obviously different for they are either an infinitive phrase or participial
phrase.
