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.

Input: Consider Input: Passage: Public transport in the city consists primarily of a First West of England bus network. Other providers are Abus, Stagecoach West, Stagecoach South West and Wessex Bus. Bristol's bus service has been criticised as unreliable and expensive, and in 2005 FirstGroup was fined for delays and safety violations.Although the city council has included a light rail system in its local transport plan since 2000, it has not yet funded the project; Bristol was offered European Union funding for the system, but the Department for Transport did not provide the required additional funding. The most recent light rail proposal was put forward as part of a consultation produced by the West of England Local Enterprise Partnership in November 2016, outlining potential light rail/tram routes from the city centre to Bristol Airport, the eastern and north west fringes of the city, and a route along the A4 road to Bath. In 2017, a further feasibility study will be undertaken into the possibility of an underground light rail system.A new bus rapid transit system (BRT) called MetroBus, is currently under construction across Bristol, as of 2018, to provide a faster and more reliable service than buses, improve transport infrastructure and reduce congestion. The MetroBus rapid transit scheme will run on both bus lanes and segregated guided busways on three routes; North Fringe to Hengrove (route m1), Ashton Vale to Bristol Temple Meads (route m2), and Emersons Green to The Centre (route m3). MetroBus services started in 2018.Three park and ride sites serve Bristol.
The city centre has water transport operated by Bristol Ferry Boats, Bristol Packet Boat Trips and Number Seven Boat Trips, providing leisure and commuter service in the harbour.

Output: Number Seven Boat Trips operates water transport in what city?


Input: Consider Input: Passage: A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around 80 to 300 miles (130 to 480 km), travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to 65 miles per hour (105 km/h) and are up to 45 feet (14 metres) high.A trigger event on the continental shelf may cause a local tsunami on the land side and a distant tsunami that travels out across the ocean. The energy of the wave is dissipated only gradually, but is spread out over the wave front, so as the wave radiates away from the source, the front gets longer and the average energy reduces, so distant shores will, on average, be hit by weaker waves. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front - an effect known as refraction - which can focus the strength of the advancing tsunami on some areas and weaken it in others according to undersea topography.
As a tsunami moves into shallower water its speed decreases, its wavelength shortens and its amplitude increases enormously, behaving in the same way as a wind-generated wave in shallow water, but on a vastly greater scale.  Either the trough or the crest of a tsunami can arrive at the coast first. In the former case, the sea draws back and leaves subtidal areas close to the shore exposed which provides a useful warning for people on land. When the crest arrives, it does not usually break but rushes inland, flooding all in its path. Much of the destruction may be caused by the flood water draining back into the sea after the tsunami has struck, dragging debris and people with it. Often several tsunami are caused by a single geological event and arrive at intervals of between eight minutes and two hours. The first wave to arrive on shore may not be the biggest or most destructive.  Occasionally, a tsunami may transform into a bore, typically in a shallow bay or an estuary.

Output: What two types of tsunami's can a trigger event on the continental shelf cause?


Input: Consider Input: 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.
Output: What had almost entirely disappeared from Bach's compositions?
