input question: Question: "What is the name of the belt system which brings rain to the Sahel and the southern Sahara?" Context: "The primary source of rain in the Sahara is the equatorial low a continuous belt of low-pressure systems near the equator which bring the brief, short and irregular rainy season to the Sahel and the southern Sahara. The Sahara doesn't lack precipitation because of a lack of moisture, but due to the lack of a precipitation-generating mechanism. Rainfall in this giant desert has to overcome the physical and atmospheric barriers that normally prevent the production of precipitation. The harsh climate of the Sahara is characterized by extremely low, unreliable, highly erratic rainfall; extremely high sunshine duration values; high temperatures year-round; negligible rates of relative humidity, a significant diurnal temperature variation and extremely high levels of potential evaporation which are the highest recorded worldwide." Answer:???
output answer: the equatorial low

Question: "How often is water that goes through SODIS used?" Context: "Solar water disinfection (SODIS) involves exposing water-filled plastic polyethylene terephthalate (PET) bottles to sunlight for several hours. Exposure times vary depending on weather and climate from a minimum of six hours to two days during fully overcast conditions. It is recommended by the World Health Organization as a viable method for household water treatment and safe storage. Over two million people in developing countries use this method for their daily drinking water." Answer:
----
Answer: daily

Q: Question: "What would one think of as seasoning, not an source of heat?" Context: "Phase change materials such as paraffin wax and Glauber's salt are another thermal storage media. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 C or 147 F). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948. Solar energy can also be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity and can deliver heat at temperatures compatible with conventional power systems. The Solar Two used this method of energy storage, allowing it to store 1.44 terajoules (400,000 kWh) in its 68 cubic metres storage tank with an annual storage efficiency of about 99%." Answer:
A: Glauber's salt

[Q]: Question: "Who gave A Night at the Opera a higher number on the chart, Q Magazine or Rolling Stone?" Context: "In late 1975, Queen recorded and released A Night at the Opera, taking its name from the popular Marx Brothers movie. At the time, it was the most expensive album ever produced. Like its predecessor, the album features diverse musical styles and experimentation with stereo sound. In "The Prophet's Song", an eight-minute epic, the middle section is a canon, with simple phrases layered to create a full-choral sound. The Mercury penned ballad, "Love of My Life", featured a harp and overdubbed vocal harmonies. The album was very successful in Britain, and went triple platinum in the United States. The British public voted it the 13th greatest album of all time in a 2004 Channel 4 poll. It has also ranked highly in international polls; in a worldwide Guinness poll, it was voted the 19th greatest of all time, while an ABC poll saw the Australian public vote it the 28th greatest of all time. A Night at the Opera has frequently appeared in "greatest albums" lists reflecting the opinions of critics. Among other accolades, it was ranked number 16 in Q Magazine's "The 50 Best British Albums Ever" in 2004, and number 11 in Rolling Stone's "The 100 Greatest Albums of All Time" as featured in their Mexican edition in 2004. It was also placed at No. 230 on Rolling Stone magazine's list of "The 500 Greatest Albums of All Time" in 2003. A Night at the Opera is the third and final Queen album to be featured in the book 1001 Albums You Must Hear Before You Die." Answer:
****
[A]: Q Magazine

Problem: Given the question: Question: "What might the Cubists have tried to avoid?" Context: "In their theoretical rules, the Cubist architects expressed the requirement of dynamism, which would surmount the matter and calm contained in it, through a creative idea, so that the result would evoke feelings of dynamism and expressive plasticity in the viewer. This should be achieved by shapes derived from pyramids, cubes and prisms, by arrangements and compositions of oblique surfaces, mainly triangular, sculpted facades in protruding crystal-like units, reminiscent of the so-called diamond cut, or even cavernous that are reminiscent of the late Gothic architecture. In this way, the entire surfaces of the facades including even the gables and dormers are sculpted. The grilles as well as other architectural ornaments attain a three-dimensional form. Thus, new forms of windows and doors were also created, e. g. hexagonal windows. Czech Cubist architects also designed Cubist furniture." Answer:
