Question: In some Muslim countries DST is temporarily abandoned during Ramadan (the month when no food should be eaten between sunrise and sunset), since the DST would delay the evening dinner. Ramadan took place in July and August in 2012. This concerns at least Morocco and Palestine, although Iran keeps DST during Ramadan. Most Muslim countries do not use DST, partially for this reason.
Is there an answer to this question: What Muslim country continues to observe DST during Ramadan?

Answer: Iran


Question: Plant circadian rhythms tell the plant what season it is and when to flower for the best chance of attracting pollinators. Behaviors showing rhythms include leaf movement, growth, germination, stomatal/gas exchange, enzyme activity, photosynthetic activity, and fragrance emission, among others. Circadian rhythms occur as a plant entrains to synchronize with the light cycle of its surrounding environment. These rhythms are endogenously generated and self-sustaining and are relatively constant over a range of ambient temperatures. Important features include two interacting transcription-translation feedback loops: proteins containing PAS domains, which facilitate protein-protein interactions; and several photoreceptors that fine-tune the clock to different light conditions. Anticipation of changes in the environment allows appropriate changes in a plant's physiological state, conferring an adaptive advantage. A better understanding of plant circadian rhythms has applications in agriculture, such as helping farmers stagger crop harvests to extend crop availability and securing against massive losses due to weather.
Is there an answer to this question: What does adaptive advantage allow for plants?

Answer: Anticipation of changes


Question: As of 18 June 2012, the ECB in total had spent €212.1bn (equal to 2.2% of the Eurozone GDP) for bond purchases covering outright debt, as part of its Securities Markets Programme (SMP) running since May 2010. On 6 September 2012, the ECB announced a new plan for buying bonds from eurozone countries. The duration of the previous SMP was temporary, while the Outright Monetary Transactions (OMT) programme has no ex-ante time or size limit. On 4 September 2014, the bank went further by announcing it would buy bonds and other debt instruments primarily from banks in a bid to boost the availability of credit for businesses.
Is there an answer to this question: What is the duration of the Outright Monetary Transactions program?

Answer: no ex-ante time or size limit


Question: Two of Chopin's long-standing pupils, Karol Mikuli (1821–1897) and Georges Mathias, were themselves piano teachers and passed on details of his playing to their own students, some of whom (such as Raoul Koczalski) were to make recordings of his music. Other pianists and composers influenced by Chopin's style include Louis Moreau Gottschalk, Édouard Wolff (1816–1880) and Pierre Zimmermann. Debussy dedicated his own 1915 piano Études to the memory of Chopin; he frequently played Chopin's music during his studies at the Paris Conservatoire, and undertook the editing of Chopin's piano music for the publisher Jacques Durand.
Is there an answer to this question: What music did Debussy play a lot at the Paris Conservatoire?

Answer:
Chopin's
