Input: Read this: David Archuleta's performance of John Lennon's "Imagine" was considered by many as one of the best of the season.

QUES: General Electric heavily contaminated the Hudson River with polychlorinated biphenyls (PCBs) between 1947-77. This pollution caused a range of harmful effects to wildlife and people who eat fish from the river or drink the water. In response to this contamination, activists protested in various ways. Musician Pete Seeger founded the Hudson River Sloop Clearwater and the Clearwater Festival to draw attention to the problem. The activism led to the site being designated by the EPA as one of the superfund sites requiring extensive cleanup. Other sources of pollution, including mercury contamination and sewage dumping, have also contributed to problems in the Hudson River watershed.
In what time period did GE pollute the Hudson River with PCBs?

ANS: 1947-77

On 18 January 2014, the interim government instituted a new constitution following a referendum in which 98.1% of voters were supportive. Participation was low with only 38.6% of registered voters participating although this was higher than the 33% who voted in a referendum during Morsi's tenure. On 26 March 2014 Abdel Fattah el-Sisi the head of the Egyptian Armed Forces, who at this time was in control of the country, resigned from the military, announcing he would stand as a candidate in the 2014 presidential election. The poll, held between 26 and 28 May 2014, resulted in a landslide victory for el-Sisi. Sisi was sworn into office as President of Egypt on 8 June 2014. The Muslim Brotherhood and some liberal and secular activist groups boycotted the vote. Even though the military-backed authorities extended voting to a third day, the 46% turnout was lower than the 52% turnout in the 2012 election.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was elected President in 2014?
Ah, so.. Abdel Fattah el-Sisi

Input: Read this: Early Presbyterians were careful to distinguish between the "church," which referred the members, and the "meeting house," which was the building in which the church met. Until the late 19th century, very few Presbyterians ever referred to their buildings as "churches." Presbyterians believed that meeting-houses (now called churches) are buildings to support the worship of God. The decor in some instances was austere so as not to detract from worship. Early Presbyterian meeting-houses were extremely plain. No stained glass, no elaborate furnishings, and no images were to be found in the meeting-house. The pulpit, often raised so as only to be accessible by a staircase, was the centerpiece of the building.
Question: What was the building where the images met called?

Output:
unanswerable
