Answer:
Pianos
Step-by-step explanation:
The word that is spelled correctly in this sentence is "pianos," as this is the plural of "piano." However, the rest of the words are misspelled. "Keys," "curiosities," and "qualities" would be the correct spelling of these words. It is easy to misspell words we do not know. Because of this, it is always useful to have a dictionary available when writing.
