Teacher: 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.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Reason: 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.

Now, solve this instance: Passage: Bach structured the cantata in eight movements: an instrumental sinfonia and seven vocal movements corresponding to the stanzas of the hymn. The duration is given as 22 minutes.The title of the original parts of the first Leipzig performance is (in Johann Christoph Altnickol's handwriting): "Feria Paschatos / Christ lag in Todes Banden / a.4. Voc: / Cornetto / 3 Trombon. / 2 Violini / 2 Viole / con / Continuo / Di Sign. Joh.Seb.Bach", In this late version, Bach scored the work for four vocal parts (soprano (S), alto (A), tenor (T), and bass (B)), and a Baroque instrumental ensemble consisting of strings, brass and continuo. The brass parts, a choir of cornetto (Ct) and three trombones (Tb) playing colla parte with the voices at times, may have been added in the 1720s. They may also possibly represent the original scoring, in the style of the 17th-century polychoral tradition.The scoring of the cantata Christ lag in Todes Banden has been described as "archaic" and its style "medieval":
The string section consists of two violin parts (Vl) and two viola parts (VA); this indicates an older practice as for instance found in 17th-century church cantatas by Bach's ancestors (see Altbachisches Archiv), and in Jesus Christus ist um unsrer Missetat willen verwundet, a Passion setting from the early 18th century (or older) which Bach had performed a few years after composing the cantata Christ lag in Todes Banden. In the first half of the 18th century the standard for a string section soon evolved to two violin parts, one viola part and continuo.
The cornett used in the cantata was an instrument that belonged to an earlier age: by the second quarter of the 18th century it had almost entirely disappeared from Bach's compositions.
The brass instruments were only used for the 1 April 1725 version of the work.  The other performances (24 April 1707, 8 April 1708, and 9 April 1724) were performed without brass instruments (i.e., Cornetto and three Trombones).
The first version (1707 and 1708) concluded with the words of Verse 7 of the Chorale, but the music was that of Movement 2 (Verse 1 of Chorale).  In 1724 and 1725, Bach changed this out to the now-used 4-part Chorale setting.
There is relatively little distinction between choral sections of the cantata and sections for vocal soloists; one editor commented that the "whole cantata may be sung as chorus". This compares to the clearer demarcation between choral movements and movements for vocal soloists in Bach's later works.  However, the number of voices the composer intended per part remains somewhat contentious, and recordings of the work differ considerably in the configurations deployed.
Student:
What had almost entirely disappeared from Bach's compositions?
