Given the task definition, example input & output, solve the new input case.
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.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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.

New input case for you: Passage: The inaugural games were held, on the orders of the Roman Emperor Titus, to celebrate the completion in AD 80 (81 according to some sources) of the Colosseum, then known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium). Vespasian began construction of the amphitheatre around AD 70 and it was completed by his son Titus who became emperor following Vespasian's death in AD 79. Titus' reign began with months of disasters – including the eruption of Mount Vesuvius, a fire in Rome, and an outbreak of plague – he inaugurated the completion of the structure with lavish games that lasted for more than one hundred days, perhaps in an attempt to appease the Roman public and the gods.
Little literary evidence survives of the activities of the gladiatorial training and fighting (ludi). They appear to have followed the standard format of the Roman games: animal entertainments in the morning session, followed by the executions of criminals around midday, with the afternoon session reserved for gladiatorial combats and recreations of famous battles. The animal entertainments, which featured creatures from throughout the Roman Empire, included extravagant hunts and fights between different species. Animals also played a role in some executions which were staged as recreations of myths and historical events. Naval battles formed part of the spectacles but whether these took place in the amphitheatre or on a lake that had been specially constructed by Augustus is a topic of debate among historians.
Only three contemporary or near-contemporary accounts of the games survive. The works of Suetonius and Cassius Dio focus on major events, while Martial provides some fragments of information on individual entertainments and the only detailed record of a gladiatorial combat in the arena known to survive: the fight between Verus and Priscus.
Output:
What games lasted for more than one hundred days?
