This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Q: Passage: Anthrozoology (also known as "human–animal studies") is the study of interaction between living things. It is a burgeoning interdisciplinary field that overlaps with a number of other disciplines, including anthropology, ethology, medicine, psychology, veterinary medicine and zoology. A major focus of anthrozoologic research is the quantifying of the positive effects of human-animal relationships on either party and the study of their interactions. It includes scholars from a diverse range of fields, including anthropology, sociology, biology, and philosophy.[n 7]

Q: Passage: The service started on 1 September 1993 based on the idea from the then chief executive officer, Sam Chisholm and Rupert Murdoch, of converting the company business strategy to an entirely fee-based concept. The new package included four channels formerly available free-to-air, broadcasting on Astra's satellites, as well as introducing new channels. The service continued until the closure of BSkyB's analogue service on 27 September 2001, due to the launch and expansion of the Sky Digital platform. Some of the channels did broadcast either in the clear or soft encrypted (whereby a Videocrypt decoder was required to decode, without a subscription card) prior to their addition to the Sky Multichannels package. Within two months of the launch, BSkyB gained 400,000 new subscribers, with the majority taking at least one premium channel as well, which helped BSkyB reach 3.5 million households by mid-1994. Michael Grade criticized the operations in front of the Select Committee on National Heritage, mainly for the lack of original programming on many of the new channels.

A: What platform helped BSkyB to avoid ending their analogue service?

Q: Passage: Some Christians argue that the earliest source of political federalism (or federalism in human institutions; in contrast to theological federalism) is the ecclesiastical federalism found in the Bible. They point to the structure of the early Christian Church as described (and prescribed, as believed by many) in the New Testament. In their arguments, this is particularly demonstrated in the Council of Jerusalem, described in Acts chapter 15, where the Apostles and elders gathered together to govern the Church; the Apostles being representatives of the universal Church, and elders being such for the local church. To this day, elements of federalism can be found in almost every Christian denomination, some more than others.

A:
When was the latest source of political federalism according to Christians?
