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: The Balts were largely driven to unite by external threats from aggressive German religious orders. In 1202, the Order of the Livonian Brothers of the Sword was established by Albert, the Bishop of Riga, to promote the Christianization and conquest of the Livonians, Curonians, Semigallians, and Estonians near the Gulf of Riga. The Order waged a number of successful campaigns and posed a great danger to the Lithuanian territories. The Order's progress was halted by its defeat at the Battle of Saule in 1236, after which it almost collapsed. The following year, it merged into the Teutonic Knights.In 1226, Konrad I of Masovia invited the Teutonic Knights to defend his borders and subdue the Prussians, offering the Knights the use of Chełmno (Kulm) as a base for their campaign. In 1230, they settled in Chełmno, built a castle, and began attacking Prussian lands. After 44 years, and despite two Prussian uprisings against them, they had conquered most of the Prussian tribes. Afterwards, the Knights spent nine years conquering the Nadruvians, Skalvians, and Yotvingians, and from 1283, they were better positioned to threaten the young Lithuanian state from the west.
Further unification of the Lithuanian tribes was facilitated by the social changes that took place in Lithuania during this period. Private land ownership was established (allodiums, Lithuanian: atolai), which would later evolve into a feudal system. As attested by many chronicles, it was the principal form of organization governing land ownership in the 13th century. Under this system, known in England as primogeniture, only the eldest son could inherit lands, which allowed dukes to consolidate their holdings. Social classes and divisions of labor also began taking shape. There were classes of experienced soldiers (bajoras), of free peasants (laukininkas), and of "unfree" people (kaimynas and šeimynykštis). In order to enforce this social structure, a united state was needed. Another force behind unification was the desire to take advantage of Ruthenian lands, which were suffering from the Mongol invasion. Temporary alliances among Lithuanian dukes often sufficed for military ventures into, and plundering of, these lands (including Pskov, plundered in 1213). Altogether, between 1201 and 1236, Lithuanians launched at least 22 incursions into Livonia, 14 into Rus, and 4 into Poland. The ongoing administration of conquered territories, however, required a strong and unified central power.

Ex Output:
What is the full name of the group that posed a great danger to the Lithuanian territories and waged a number of successful campaigns?

Passage: The film opens on ancient Greek ruins where a chanting Greek chorus introduces and narrates the story of Lenny Weinrib. Lenny is a sportswriter in Manhattan, married to ambitious curator Amanda. The couple decide to adopt a baby, a boy they name Max. Lenny is awed by their son who, it becomes increasingly clear, is a gifted child.
Lenny becomes obsessed with learning the identity of Max's biological mother. After a long search, Lenny is disturbed to find that she is a prostitute and part-time porn star, who uses several names but confesses her birth name is Leslie, and she likes "Linda" because it means beautiful in Spanish, so her current porn star name is Linda Ash. Lenny makes an "appointment" to see her at her apartment. Linda is a bit of a ditz with a crude sense of humor and delusions of becoming a stage actress. Lenny does not have intercourse with her but instead urges her to get away from prostitution and start a wholesome life. Linda becomes angry, refunds Lenny's money, and forces him to leave. Lenny, however, is determined to befriend her and improve her life. He first manages to get Linda away from her violent pimp and then attempts to pair Linda with a former boxer, Kevin. They appear to be a well-suited couple until Kevin discovers Linda's background.

Ex Output:

What is Max's adoptive father introduced by?
