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.
One 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.
Solution is here: Who believes Fagin's gang make wallets and handkerchiefs?.
Explanation: 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.

Now, solve this: Passage: Fishing season has begun and park ranger J. Audubon Woodlore goes out on the lake to check on the anglers. Humphrey the Bear is trying to catch some fish, but cannot seem to hold onto one once he catches it.  Woodlore sees the fish disappearing before his eyes, so he decides to stock the lake some more. As he heads to the fish hatchery, he sees Humphrey with a few fishing nets and rods, and asks him what he is doing.  When the bear tells him that he is going to catch some fish, Woodlore takes the rods and nets and tells him to "Go fish like a bear!" At the hatchery, Woodlore selects an envelope of fish eggs from a collection of eggs from such trout species as dolly vardens and rainbows. He fills a tub with water and inserts the eggs into it.  In a matter of seconds, several fishes pop up out of the water like plants out of soil.
When the ranger gets to the lake to dump the fish, he finds Humphrey in there, trying to eat one of the small fishes, which is then consumed by a much larger fish. Humphrey manages to remove the small fish from the mouth of the large fish, and then uses it to lure five other large fishes that jump out of the water, but then Woodlore appears to measure the fish, while at the same time punishing Humphrey by hitting him on the head, causing him to sink into the depths of the lake. When Humphrey grabs some more fish and emerges from the lake, he discovers a fish larger than any of the others; this turns out to be a fish balloon with which a young boy is playing. Humphrey pops the balloon, and both the boy and Woodlore kick the bear in the knee.
Solution:
What is the largest fish in the lake?
