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 Chemno (Kulm) as a base for their campaign. In 1230, they settled in Chemno, 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 seimynykstis). 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.

In his English class, Jason gives Anastacia a poem he wrote about her after she forgets to do the homework assignment expect the teacher makes her read it in front of the class which everyone including Anastacia finds to be very great. After school is over, Anastacia gives Jason her number so they can write a song together sometime.

Passage: Imogen Clare Holst (nee von Holst; 12 April 1907 9 March 1984) was a British composer, arranger, conductor, teacher, musicologist, and festival administrator. The only child of the composer Gustav Holst, she is particularly known for her educational work at Dartington Hall in the 1940s, and for her 20 years as joint artistic director of the Aldeburgh Festival. In addition to composing music, she wrote composer biographies, much educational material, and several books on the life and works of her father.
From a young age, Holst showed precocious talent in composing and performance. After attending Eothen School and St Paul's Girls' School, she entered the Royal College of Music, where she developed her skills as a conductor and won several prizes for composing. Unable for health reasons to follow her initial ambitions to be a pianist or a dancer, Holst spent most of the 1930s teaching, and as a full-time organiser for the English Folk Dance and Song Society. These duties reduced her compositional activities, although she made many arrangements of folksongs. After serving as an organiser for the Council for the Encouragement of Music and the Arts at the start of the Second World War, in 1942 she began working at Dartington. In her nine years there she established Dartington as a major centre of music education and activity.
In the early 1950s Holst became Benjamin Britten's musical assistant, moved to Aldeburgh, and began helping with the organisation of the annual Aldeburgh Festival. In 1956 she became joint artistic director of the festival, and during the following 20 years helped it to a position of pre-eminence in British musical life. In 1964 she gave up her work as Britten's assistant, to resume her own compositional career and to concentrate on the preservation of her father's musical legacy. Her own music is not widely known and has received little critical attention; much of it is unpublished and unperformed. The first recordings dedicated to her works, issued in 2009 and 2012, were warmly received by critics. She was appointed CBE in 1975 and received numerous academic honours. She died at Aldeburgh and is buried in the churchyard there.
