instruction:
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.
question:
Passage: In regard to companies, the Court of Justice held in R (Daily Mail and General Trust plc) v HM Treasury that member states could restrict a company moving its seat of business, without infringing TFEU article 49. This meant the Daily Mail newspaper's parent company could not evade tax by shifting its residence to the Netherlands without first settling its tax bills in the UK. The UK did not need to justify its action, as rules on company seats were not yet harmonised. By contrast, in Centros Ltd v Erhversus-og Selkabssyrelsen the Court of Justice found that a UK limited company operating in Denmark could not be required to comply with Denmark's minimum share capital rules. UK law only required £1 of capital to start a company, while Denmark's legislature took the view companies should only be started up if they had 200,000 Danish krone (around €27,000) to protect creditors if the company failed and went insolvent. The Court of Justice held that Denmark's minimum capital law infringed Centros Ltd's freedom of establishment and could not be justified, because a company in the UK could admittedly provide services in Denmark without being established there, and there were less restrictive means of achieving the aim of creditor protection. This approach was criticised as potentially opening the EU to unjustified regulatory competition, and a race to the bottom in standards, like in the US where the state Delaware attracts most companies and is often argued to have the worst standards of accountability of boards, and low corporate taxes as a result. Similarly in Überseering BV v Nordic Construction GmbH the Court of Justice held that a German court could not deny a Dutch building company the right to enforce a contract in Germany on the basis that it was not validly incorporated in Germany. Although restrictions on freedom of establishment could be justified by creditor protection, labour rights to participate in work, or the public interest in collecting taxes, denial of capacity went too far: it was an "outright negation" of the right of establishment. However, in Cartesio Oktató és Szolgáltató bt the Court of Justice affirmed again that because corporations are created by law, they are in principle subject to any rules for formation that a state of incorporation wishes to impose. This meant that the Hungarian authorities could prevent a company from shifting its central administration to Italy while it still operated and was incorporated in Hungary. Thus, the court draws a distinction between the right of establishment for foreign companies (where restrictions must be justified), and the right of the state to determine conditions for companies incorporated in its territory, although it is not entirely clear why.
answer:
Who riled that member stated could not restrict a company from moving its seat of business without infringing TFEU article 49?


question:
Passage: The name of the metal was probably first documented by Paracelsus, a Swiss-born German alchemist, who referred to the metal as "zincum" or "zinken" in his book Liber Mineralium II, in the 16th century. The word is probably derived from the German zinke, and supposedly meant "tooth-like, pointed or jagged" (metallic zinc crystals have a needle-like appearance). Zink could also imply "tin-like" because of its relation to German zinn meaning tin. Yet another possibility is that the word is derived from the Persian word سنگ seng meaning stone. The metal was also called Indian tin, tutanego, calamine, and spinter.
answer:
Who is attributed as the only person to document zinc?


question:
Passage: In 2006–07, researchers from the Wildlife Conservation Society studied gorillas in heavily forested regions centered on the Ouesso district of the Sangha Region. They suggest a population on the order of 125,000 Western Lowland Gorillas, whose isolation from humans has been largely preserved by inhospitable swamps.
answer:

When did researchers from the Wildlife Conservation Society study chimps?
