TASK DEFINITION: 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.
PROBLEM: Passage: Bach is believed to have written Christ lag in Todes Banden in 1707. He was a professional organist aged 22, employed from 1703 in Arnstadt as the organist of the New Church (which replaced the burned Bonifatiuskirche, today known as the Bach Church). At age 18, he had inspected the new organ built by Johann Friedrich Wender, was invited to play one Sunday, and was hired. The organ was built on the third tier of a theatre-like church. Bach's duties as a church musician involved some responsibility for choral music, but the exact year he began composing cantatas is unknown. Christ lag in Todes Banden is one of a small group of cantatas that survive from his early years. According to the musicologist Martin Geck, many details of the score reflect "organistic practice".In Arnstadt, the Kantor (church musician) Heindorff was responsible for church music in the Upper Church (Liebfrauenkirche), and the New Church where Bach was the organist. He typically conducted music in the Upper Church and would appoint a choir prefect for vocal music in the New Church. Wolff notes that "subjecting his works to the questionable leadership of a prefect" was not what Bach would have done. Therefore, most cantatas of the period are not for Sunday occasions, but restricted to special occasions such as weddings and funerals. Christ lag in Todes Banden is the only exception, but was most likely composed not for Arnstadt but for an application to a more important post at the Divi Blasii church in Mühlhausen.

SOLUTION: What was the name of the Bach Church when Bach was the organist?

PROBLEM: Passage: The NSWCA appealed to Lord Harris, and in reply he said he did not blame them or the cricketers of Sydney in any way, but said that "it [the riot] was an occurrence it was impossible he could forget".
On 11 February, one day after the conclusion of the match and three days after the riot, Harris wrote a letter to one of his friends about the disturbance. It was clear that he intended the letter to be printed in the press, and it appeared in full in The Daily Telegraph on 1 April, among other London newspapers, reigniting the furore. Wisden Cricketers' Almanack considered the incident of such significance that it reprinted the whole correspondence. The letter gives a detailed contemporary account of what Lord Harris thought about the riot.Lord Harris referred to the crowd as a "howling mob" and said "I have seen no reason as yet to change my opinion of Coulthard's qualities, or to regret his engagement, in which opinion I am joined by the whole team". He further added that "Beyond slyly kicking me once or twice the mob behaved very well, their one cry being, 'Change your umpire'. And now for the cause of this disturbance, not unexpected, I may say, by us, for we have heard accounts of former matches played by English teams." Harris further accused a New South Wales parliamentarian of assisting the gamblers in the inciting the unrest, although he did not name the accusee. He said
I blame the NSW Eleven for not objecting to Coulthard before the match began, if they had reason to suppose him incompetent to fulfil his duties. I blame the members of the association (many, of course, must be excepted) for their discourtesy and uncricket like behaviour to their guests; and I blame the committee and others of the association for ever permitting betting, but this last does not, of course, apply to our match only. I am bound to say they did all in their power to quell the disturbance. I don't think anything would have happened if A. Bannerman had been run out instead of Murdoch, but the latter, besides being a great favourite, deservedly I think, was the popular idol of the moment through having carried his bat out in the first innings.
He further accused the Australian public of being bad losers, claiming that they were sparing in their applause upon his team's victory, and were unable to appreciate skills shown by an opposing team. He summed up his feelings
To conclude, I cannot describe to you the horror we felt that such an insult should have been passed on us, and that the game we love so well, and wish to see honoured, supported, and played in an honest and manly way everywhere, should receive such desecration. I can use no milder word.

SOLUTION: What is the full name of the person who wrote to his friend about the disturbance?

PROBLEM: Passage: While Leonard Harrison and Colton Point State Parks and parts of the surrounding Tioga State Forest are now the Pine Creek Gorge National Natural Landmark, it is their status as part of a Pennsylvania State Natural Area that provides the strongest protection for them. Within this Natural Area, all logging, mining, and oil and gas drilling are prohibited, and only foot trail access is allowed. In 1988 the Pennsylvania Department of Environmental Resources, precursor to the DCNR, described it as about 95% State owned, unroaded, and designated the Pine Creek Gorge Natural Area. It is a place of unique geologic history and contains some rare plant communities, an old growth hemlock stand, ... active bald eagle nest[s] ... and is a major site of river otter reintroduction. Departmental policy is protection of the natural values of the Canyon from development and overuse, and restoration of the area to as near a natural condition as possible.
The gorge has over 225 species of wildflowers, plants and trees,  with scattered stands of old growth forest on some of its steepest walls. The rest of the gorge is covered with thriving second growth forest that can be over one hundred years old. However, since clearcutting, nearly 90 percent of the forest land has burnt at least once. Typical south-facing slopes here have mountain laurel below oak and hickory trees, while north-facing slopes tend to have ferns below hemlocks and hardwoods. Large chestnuts and black cherry can also be found.The Grand Canyon of Pennsylvania is known for its fall foliage, and Leonard Harrison State Park is a popular place to observe the colors, with the first three weeks of October as the best time to see the leaves in their full color. Red leaves are found on red maple, red oak, and black cherry, while orange and yellow leaves are on black walnut, sugar maple, aspen, birch, tulip poplar and chestnut oak, and brown leaves are from beech, white oak, and eastern black oak trees. Plants of "special concern" in Pennsylvania that are found in the gorge include Jacob's ladder, wild pea, and hemlock parsley.

SOLUTION:
What are the three listed plants of "special concern" that are found in the gorge that has over 225 species of wildflowers?
