Question: Passage: Luther's hymns were frequently evoked by particular events in his life and the unfolding Reformation. This behavior started with his learning of the execution of Johann Esch and Heinrich Voes, the first individuals to be martyred by the Roman Catholic Church for Lutheran views, prompting Luther to write the hymn 'Ein neues Lied wir heben an' ('A new song we raise'), which is generally known in English by John C. Messenger's translation by the title and first line 'Flung to the Heedless Winds' and sung to the tune Ibstone composed in 1875 by Maria C. Tiddeman. Question: What caused Luther to write hymns?

Answer: events in his life


Question: Passage: Somewhere around a billion years ago, a free-living cyanobacterium entered an early eukaryotic cell, either as food or as an internal parasite, but managed to escape the phagocytic vacuole it was contained in. The two innermost lipid-bilayer membranes that surround all chloroplasts correspond to the outer and inner membranes of the ancestral cyanobacterium's gram negative cell wall, and not the phagosomal membrane from the host, which was probably lost. The new cellular resident quickly became an advantage, providing food for the eukaryotic host, which allowed it to live within it. Over time, the cyanobacterium was assimilated, and many of its genes were lost or transferred to the nucleus of the host. Some of its proteins were then synthesized in the cytoplasm of the host cell, and imported back into the chloroplast (formerly the cyanobacterium). Question: What surrounds chloroplasts?

Answer: two innermost lipid-bilayer membranes


Question: Passage: On 8 February 2007, BSkyB announced its intention to replace its three free-to-air digital terrestrial channels with four subscription channels. It was proposed that these channels would offer a range of content from the BSkyB portfolio including sport (including English Premier League Football), films, entertainment and news. The announcement came a day after Setanta Sports confirmed that it would launch in March as a subscription service on the digital terrestrial platform, and on the same day that NTL's services re-branded as Virgin Media. However, industry sources believe BSkyB will be forced to shelve plans to withdraw its channels from Freeview and replace them with subscription channels, due to possible lost advertising revenue. Question: What does BSkyB's sport portfolio include?

Answer:
English Premier League Football
