instruction:
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.
answer:
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: One of Greenway's finest works, St James' is listed on the (now defunct) Register of the National Estate. It has been called an "architectural gem" and was featured by Dan Cruickshank in the BBC television series Around the World in 80 Treasures. From 1966 to 1993 the spire of St James' appeared on the Australian Australian ten-dollar note among other Greenway buildings. In 1973, the church appeared on a 50 cent postage stamp, one of four in a series illustrating Australian architecture issued to commemorate the opening of the Sydney Opera House. The Old Supreme Court building, also designed by Greenway with alternations by others, located next to the church is of the same date. Across the square is Greenway's "masterpiece", the UNESCO World Heritage listed-Hyde Park Barracks, designed to align with the church. Beside the barracks stands Sydney's oldest public building, part of the General Hospital built in 1811 and now known as the Mint Building. Separated from the Mint by the present-day Sydney Hospital is Parliament House, Sydney, of which the central section is a further part of the early hospital, and is now home to the New South Wales State Parliament.The church was constructed between 1820 and 1824 with later additions made in 1834 by John Verge who designed the vestries at the eastern end. Apart from these vestries, which retain the established style and proportions, the church externally remains "fine Georgian" much as Greenway conceived it. Relying on the "virtues of simplicity and proportion to achieve his end", Greenway maintained the classical tradition, unaffected by the Revivalist styles that were being promoted in London at the time he arrived in the colony. He planned the church to align with his earlier Hyde Park Barracks, constructed in 181719. The two buildings have similar proportions, pilasters and gables and together constitute an important example of town-planning. Before the advent of high-rise buildings, the 46-metre (150 ft) spire used to "serve as a guide for mariners coming up Port Jackson".St James' originally took the form of a simple rectangular block, without transepts or chancel, with a tower at the western end and a classical portico of the Doric order on either side. To this has been added Verge's vestry framed by two small porticos, and a similar portico as an entrance to the tower. The church is built of local brick, its walls divided by brick pilasters into a series of bays. The walls are pierced by large windows with round arched heads in a colour that separates and defines them against the walls. The roof carries over the end walls with the gable forming triangular pediments of classical proportions carrying a cornice across the eaves line. Thus the architectural treatment on the side walls is continued around the end walls.

What is the name of that which is called an architectural gem and was featured by Dan Cruickshank in a BBC television series?

Passage: In 1975, the Jackson 5 left Motown. They signed with Epic Records, a subsidiary of CBS Records, and renamed themselves the Jacksons. Their younger brother Randy joined the band around this time; Jermaine stayed with Motown and pursued a solo career. The Jacksons continued to tour internationally, and released six more albums between 1976 and 1984. Michael, the group's main songwriter during this time, wrote songs such as "Shake Your Body (Down to the Ground)" (1979), "This Place Hotel" (1980), and "Can You Feel It" (1980).In 1978, Jackson moved to New York City to star as the Scarecrow in The Wiz, a musical directed by Sidney Lumet. It costarred Diana Ross, Nipsey Russell, and Ted Ross. The film was a box-office failure. Its score was arranged by Quincy Jones, who later produced three of Jackson's solo albums. During his time in New York, Jackson frequented the Studio 54 nightclub, where he heard early hip hop; this influenced his beatboxing on future tracks such as "Working Day and Night". In 1979, Jackson broke his nose during a dance routine. A rhinoplasty led to breathing difficulties that later affected his career. He was referred to Steven Hoefflin, who performed Jackson's subsequent operations.Jackson's fifth solo album, Off the Wall (1979) established him as a solo performer and helped him move from the bubblegum pop of his youth to more complex sounds. It produced four top 10 entries in the US: "Off the Wall", "She's Out of My Life", and the chart-topping singles "Don't Stop 'Til You Get Enough" and "Rock with You". The album reached number three on the US Billboard 200 and sold over 20 million copies worldwide. In 1980, Jackson won three American Music Awards for his solo work: Favorite Soul/R&B Album, Favorite Soul/R&B Male Artist, and Favorite Soul/R&B Single for "Don't Stop 'Til You Get Enough". He also won a Grammy Award for Best Male R&B Vocal Performance for 1979 with "Don't Stop 'Til You Get Enough". In 1981 Jackson was the American Music Awards winner for Favorite Soul/R&B Album and Favorite Soul/R&B Male Artist. Jackson felt Off the Wall should have made a bigger impact, and was determined to exceed expectations with his next release. In 1980, he secured the highest royalty rate in the music industry: 37 percent of wholesale album profit.
