10. Despite the notion she had that there were blue butterflies in her hair that liked to eat dandruff, she sensed that they would not be satisfied to feast or fine dine on the follicle although she understood that soon the poor butterflies would be poisoned by her hair spray.

One way to answer this question is to set off the long "Despite the notion she had that there were blue butterflies in her hair that liked to eat dandruff" with a comma. This is a bulky construction that consists of a prepositinal phrase, a relative clause, a noun cluase and another relative clause all before one gets to the main clause.

Also, "although" is a subordinating conjunction that indicates "although she understood that soon the poor butterflies would be poisoned by her hair spray" is a dependent clause. Because this dependent clause occurs after the main clause, it is not set off with a comma.
