In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Let me give you an example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
The answer to this example can be: Who believes Fagin's gang make wallets and handkerchiefs?.
Here is why: This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

OK. solve this:
Passage: Right before Berk's traditional winter holiday of Snoggletog, all the dragons of Berk unexpectedly depart, leaving everyone distraught - except for Toothless, who cannot fly by himself. Out of compassion, Hiccup builds him a new automatic prosthesis allowing him independent flight, thus gifting him his freedom; he then flies off too.
Three days later, Meatlug, Fishlegs's dragon whom he had secretly kept chained, escapes, inadvertently taking Hiccup with him. Meatlug flies to an island with hot springs, where all the dragons (except Toothless, whom is nowhere to be found) have been hatching their eggs. Meanwhile, on Berk, Astrid and the other youth discover dragon eggs in Meatlug's nest, which they scatter around Berk in hopes of lifting the villagers' spirits; this plan backfires because dragon eggs hatch explosively (normally underwater), devastating Berk.
On the dragons' island, Hiccup meets Stormfly (Astrid's dragon) and Hookfang (Snotlout's dragon) and their newly-hatched babies; in asking for a ride home, he inadvertently triggers the dragons' return migration. He quickly decides to use a nearby wrecked ship to carry the baby dragons who cannot yet fly all the way back to Berk. The Berkians are overjoyed at their dragons' return and the new babies; yet, Hiccup is still distraught at Toothless's absence. During the ensuing Snoggletog celebration, Toothless returns with Hiccup's lost helmet, which he had dropped into the sea earlier; the two enjoy a heartfelt reunion.
The next day, Toothless destroys his new tail, begging Hiccup to put the old tailfin on him and fly with him by controlling his fin manually as opposed to merely on him; in doing so, he gives Hiccup a "better gift" - his friendship and companionship.
Answer:
What is on the island where Hiccup meets Stormfly and Hookfang?
