In this task, you are given a passage and a question regarding that passage. You must determine whether or not the question is answerable from the given passage. If a question is answerable, output should be 'True', otherwise 'False'. You must not consider any other information that is not provided in the passage while labelling True or False.

Q: Passage: When some species, including Bathyctena chuni, Euplokamis stationis and Eurhamphaea vexilligera, are disturbed, they produce secretions (ink) that luminesce at much the same wavelengths as their bodies. Juveniles will luminesce more brightly in relation to their body size than adults, whose luminescence is diffused over their bodies. Detailed statistical investigation has not suggested the function of ctenophores' bioluminescence nor produced any correlation between its exact color and any aspect of the animals' environments, such as depth or whether they live in coastal or mid-ocean waters. Question: What do Bathyctena chuni, Euplokamis stationis and Euhamphaea veilligera produce only when they change color?

A: False

Q: Passage: As well as creating rights for "workers" who generally lack bargaining power in the market, the Treaty on the Functioning of the European Union also protects the "freedom of establishment" in article 49, and "freedom to provide services" in article 56. In Gebhard v Consiglio dell’Ordine degli Avvocati e Procuratori di Milano the Court of Justice held that to be "established" means to participate in economic life "on a stable and continuous basis", while providing "services" meant pursuing activity more "on a temporary basis". This meant that a lawyer from Stuttgart, who had set up chambers in Milan and was censured by the Milan Bar Council for not having registered, was entitled to bring a claim under for establishment freedom, rather than service freedom. However, the requirements to be registered in Milan before being able to practice would be allowed if they were non-discriminatory, "justified by imperative requirements in the general interest" and proportionately applied. All people or entities that engage in economic activity, particularly the self-employed, or "undertakings" such as companies or firms, have a right to set up an enterprise without unjustified restrictions. The Court of Justice has held that both a member state government and a private party can hinder freedom of establishment, so article 49 has both "vertical" and "horizontal" direct effect. In Reyners v Belgium the Court of Justice held that a refusal to admit a lawyer to the Belgian bar because he lacked Belgian nationality was unjustified. TFEU article 49 says states are exempt from infringing others' freedom of establishment when they exercise "official authority", but this did an advocate's work (as opposed to a court's) was not official. By contrast in Commission v Italy the Court of Justice held that a requirement for lawyers in Italy to comply with maximum tariffs unless there was an agreement with a client was not a restriction. The Grand Chamber of the Court of Justice held the Commission had not proven that this had any object or effect of limiting practitioners from entering the market. Therefore, there was no prima facie infringement freedom of establishment that needed to be justified. Question: What do workers generally have in the market?

A: False

Q: Passage: The plague theory was first significantly challenged by the work of British bacteriologist J. F. D. Shrewsbury in 1970, who noted that the reported rates of mortality in rural areas during the 14th-century pandemic were inconsistent with the modern bubonic plague, leading him to conclude that contemporary accounts were exaggerations. In 1984 zoologist Graham Twigg produced the first major work to challenge the bubonic plague theory directly, and his doubts about the identity of the Black Death have been taken up by a number of authors, including Samuel K. Cohn, Jr. (2002), David Herlihy (1997), and Susan Scott and Christopher Duncan (2001). Question: In what year did Samuel K. Cohn, Jr.  read Graham Twigg's major work?

A:
False
