Take a look at the sentence again:
Neither __________ nor the ineffective air conditioner rattling in the window
will deter Tiffany from loving the freedom of her first apartment.
The blank requires a noun phrase followed by a participle phrase. You chose playing loud music by the inconsiderate neighbors, which is a gerund phrase and thus causes a parallelism error. Before you continue, review the rules for parallel structure.
