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.

Passage: After usurping the throne of the Later Zhou dynasty, Emperor Taizu of Song (r. 960–976) spent sixteen years conquering the rest of China, reuniting much of the territory that had once belonged to the Han and Tang empires and ending the upheaval of the Five Dynasties and Ten Kingdoms period. In Kaifeng, he established a strong central government over the empire. The establishment of this capital marked the start of the Northern Song period. He ensured administrative stability by promoting the civil service examination system of drafting state bureaucrats by skill and merit (instead of aristocratic or military position) and promoted projects that ensured efficiency in communication throughout the empire. In one such project, cartographers created detailed maps of each province and city that were then collected in a large atlas. Emperor Taizu also promoted groundbreaking scientific and technological innovations by supporting such works as the astronomical clock tower designed and built by the engineer Zhang Sixun.The Song court maintained diplomatic relations with Chola India, the Fatimid Caliphate of Egypt, Srivijaya, the Kara-Khanid Khanate of Central Asia, the Goryeo kingdom in Korea, and other countries that were also trade partners with Japan. Chinese records even mention an embassy from the ruler of "Fu lin" (拂菻, i.e. the Byzantine Empire), Michael VII Doukas, and its arrival in 1081. However, China's closest neighbouring states had the greatest impact on its domestic and foreign policy. From its inception under Taizu, the Song dynasty alternated between warfare and diplomacy with the ethnic Khitans of the Liao dynasty in the northeast and with the Tanguts of the Western Xia in the northwest. The Song dynasty used military force in an attempt to quell the Liao dynasty and to recapture the Sixteen Prefectures, a territory under Khitan control since 938 that was traditionally considered to be part of China proper (Most parts of today's Beijing and Tianjin). Song forces were repulsed by the Liao forces, who engaged in aggressive yearly campaigns into Northern Song territory until 1005, when the signing of the Shanyuan Treaty ended these northern border clashes. The Song were forced to provide tribute to the Khitans, although this did little damage to the Song economy since the Khitans were economically dependent upon importing massive amounts of goods from the Song. More significantly, the Song state recognized the Liao state as its diplomatic equal. The Song created an extensive defensive forest along the Song-Liao border to thwart potential Khitan cavalry attacks.
What is the name of the person that supported the scientific innovations while in charge?

Passage: A boy obsessed with football finds his life changing dramatically once he adds a little Samba. Danny plays on the football team at the all-boys Catholic school he attends in Belfast. Danny's three best friends, who also play on the team, all have different ambitions for their lives. Mickey wants to be a fashion designer so he can get rich and date supermodels. Gary wants to become a magician so he can get rich and meet beautiful women (and presumably saw them in half). And Spike likes to beat people up, so he wants to become a mercenary and do it for a living. But Danny dreams of making football his life.
The players Danny most admires are South Americans, such as Pele and Carlos Riga, who he feels have a special rhythm and flexibility. Wanting to add some of these qualities to his own game, Danny has an idea: he'll take Samba lessons, in the hope that dancing like a South American will help him play like a South American. To the surprise of himself and his friends, Danny turns out to be a pretty good Latin dancer and finds himself smitten with a student in his dance class, Lucy. However, Lucy happens to have a boyfriend, who is a fierce competitor on one of Danny's rival teams. The film also stars Brian Flanagan who plays an inspiring cameo role along with members of Celbridge Town Football Club.
Who are Danny's three best friends?

Passage: It is revealed that following the end of the Norvagen/Draigar war, the Dragons briefly returned to Earth but decided to return to Dragon World and let Humans guide their own paths. Scylla, high priestess and queen of the Odaku army, along with her dragon Slann, summons the Shadow Dragons Gryndel and Daakon.  She offers to open a portal to the Dragon Realm if they aid her in conquering the Norvagen and Draigar kingdoms.
Meanwhile, Norvagen Prince Dev and Draigar Princess Kyra lead a raiding party to take out an Odaku outpost, who have been increasing attacks against them. But as they enter the outpost, the sleeping soldiers turn out to be decoys, and the raiding party is ambushed. The Odaku wear armour that repels any form of attack and they are armed with explosive weapons. Worse, the Shadow Dragons arrive, and take the souls of Targon and Aurora, Dev and Kyras Dragon companions, killing them. Seeing this, Dev goes into a battle rage. Meanwhile, Dev's and Kyras fathers worry about their children, especially Dev, who has shown signs of being a berserker, like his grandfather. After the attack, Dev and Kyra regain consciousness and find the fallen Targon and Aurora. Dev realizes he is losing control of his emotions. A second fleet of Odaku soldiers arrive and Dev and Kyra are left defenseless. A stranger approaches them and offers to aid them, and Kyra eagerly follows him, along with Dev, who is hesitant about traveling with the stranger.
In the dragon world, King Thoron refuses to interfere in human affairs, which is why they left a second time. But when he hears about the Shadow Dragons, he decides to return and finds Targon and Aurora's bodies. Though the other dragons grieve, Thoron knows that when dragons are killed by Shadow Dragons, they create the cosmic opposite, Light Dragons.
What is the name of the character who offers to open a portal to the Dragon Realm?
