Q: Extract the answer to the question from the following context. Question: How dangerous is the issue of water contamination? Context: Given that water contamination is a major means of transmitting diarrheal disease, efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease incidence. In fact, it has been proposed that we might expect an 88% reduction in child mortality resulting from diarrheal disease as a result of improved water sanitation and hygiene. Similarly, a meta-analysis of numerous studies on improving water supply and sanitation shows a 2227% reduction in disease incidence, and a 2130% reduction in mortality rate associated with diarrheal disease.
A: efforts to provide clean water supply and improved sanitation have the potential to dramatically cut the rate of disease

Q: Extract the answer to the question from the following context. Question: Which opus did Chopin reference in correspondence to Pleyel in 1839? Context: On 3 December, Chopin complained about his bad health and the incompetence of the doctors in Majorca: "Three doctors have visited me ... The first said I was dead; the second said I was dying; and the third said I was about to die." He also had problems having his Pleyel piano sent to him. It finally arrived from Paris in December. Chopin wrote to Pleyel in January 1839: "I am sending you my Preludes [(Op. 28)]. I finished them on your little piano, which arrived in the best possible condition in spite of the sea, the bad weather and the Palma customs." Chopin was also able to undertake work on his Ballade No. 2, Op. 38; two Polonaises, Op. 40; and the Scherzo No. 3, Op. 39.
A: Op. 28

Q: Extract the answer to the question from the following context. Question: In what order is this done? Context: During the ceremony of initiation, the candidate is expected to swear (usually on a volume of sacred text appropriate to his personal religious faith) to fulfil certain obligations as a Mason. In the course of three degrees, new masons will promise to keep the secrets of their degree from lower degrees and outsiders, and to support a fellow Mason in distress (as far as practicality and the law permit). There is instruction as to the duties of a Freemason, but on the whole, Freemasons are left to explore the craft in the manner they find most satisfying. Some will further explore the ritual and symbolism of the craft, others will focus their involvement on the social side of the Lodge, while still others will concentrate on the charitable functions of the lodge.
A: Freemason

Q: Extract the answer to the question from the following context. Question: Why was a contract with the gods made? Context: Extraordinary circumstances called for extraordinary sacrifice: in one of the many crises of the Second Punic War, Jupiter Capitolinus was promised every animal born that spring (see ver sacrum), to be rendered after five more years of protection from Hannibal and his allies. The "contract" with Jupiter is exceptionally detailed. All due care would be taken of the animals. If any died or were stolen before the scheduled sacrifice, they would count as already sacrificed, since they had already been consecrated. Normally, if the gods failed to keep their side of the bargain, the offered sacrifice would be withheld. In the imperial period, sacrifice was withheld following Trajan's death because the gods had not kept the Emperor safe for the stipulated period. In Pompeii, the Genius of the living emperor was offered a bull: presumably a standard practise in Imperial cult, though minor offerings (incense and wine) were also made.
A:
protection
