Input: Middle Ages
Education remained mostly focused on the training of future clergy. The basic learning of the letters and numbers remained the province of the family or a village priest, but the secondary subjects of the trivium—grammar, rhetoric, logic—were studied in cathedral schools or in schools provided by cities. Commercial secondary schools spread, and some Italian towns had more than one such enterprise. Universities also spread throughout Europe in the 14th and 15th centuries. Lay literacy rates rose, but were still low; one estimate gave a literacy rate of ten per cent of males and one per cent of females in 1500.

What was the main purpose of education in this period?
Output: training of future clergy


Input: Article: Solar concentrating technologies such as parabolic dish, trough and Scheffler reflectors can provide process heat for commercial and industrial applications. The first commercial system was the Solar Total Energy Project (STEP) in Shenandoah, Georgia, USA where a field of 114 parabolic dishes provided 50% of the process heating, air conditioning and electrical requirements for a clothing factory. This grid-connected cogeneration system provided 400 kW of electricity plus thermal energy in the form of 401 kW steam and 468 kW chilled water, and had a one-hour peak load thermal storage. Evaporation ponds are shallow pools that concentrate dissolved solids through evaporation. The use of evaporation ponds to obtain salt from sea water is one of the oldest applications of solar energy. Modern uses include concentrating brine solutions used in leach mining and removing dissolved solids from waste streams. Clothes lines, clotheshorses, and clothes racks dry clothes through evaporation by wind and sunlight without consuming electricity or gas. In some states of the United States legislation protects the "right to dry" clothes. Unglazed transpired collectors (UTC) are perforated sun-facing walls used for preheating ventilation air. UTCs can raise the incoming air temperature up to 22 °C (40 °F) and deliver outlet temperatures of 45–60 °C (113–140 °F). The short payback period of transpired collectors (3 to 12 years) makes them a more cost-effective alternative than glazed collection systems. As of 2003, over 80 systems with a combined collector area of 35,000 square metres (380,000 sq ft) had been installed worldwide, including an 860 m2 (9,300 sq ft) collector in Costa Rica used for drying coffee beans and a 1,300 m2 (14,000 sq ft) collector in Coimbatore, India, used for drying marigolds.

Now answer this question: What is one of the oldest uses of solar energy?

Output: use of evaporation ponds to obtain salt from sea water


Article: In-mid 2015, China started the build-up of the third generation BeiDou system (BDS-3) in the global coverage constellation. The first BDS-3 satellite was launched 30 September 2015. As of March 2016, 4 BDS-3 in-orbit validation satellites have been launched.

Question: When did China begin constructing the third BeiDou system?
Ans: mid 2015


Here is a question about this article: Inside ornament was far more generous, and could sometimes be overwhelming. The chimneypiece continued to be the usual main focus of rooms, and was now given a classical treatment, and increasingly topped by a painting or a mirror. Plasterwork ceilings, carved wood, and bold schemes of wallpaint formed a backdrop to increasingly rich collections of furniture, paintings, porcelain, mirrors, and objets d'art of all kinds. Wood-panelling, very common since about 1500, fell from favour around the mid-century, and wallpaper included very expensive imports from China.
What is the answer to this question: Where was very expensive wallpaper imported from?
****
So... China


The problem: Answer a question about this article:
Galicia is further divided into 53 comarcas, 315 municipalities (93 in A Coruña, 67 in Lugo, 92 in Ourense, 62 in Pontevedra) and 3,778 parishes. Municipalities are divided into parishes, which may be further divided into aldeas ("hamlets") or lugares ("places"). This traditional breakdown into such small areas is unusual when compared to the rest of Spain. Roughly half of the named population entities of Spain are in Galicia, which occupies only 5.8 percent of the country's area. It is estimated that Galicia has over a million named places, over 40,000 of them being communities.
How many municipalities?
****
The answer: 315


The problem: Answer a question about this article:
Over the years, AC has spawned subgenres including "hot AC", "soft AC" (also known as "lite AC"), "urban AC", "rhythmic AC", and "Christian AC" (a softer type of contemporary Christian music). Some stations play only "hot AC", "soft AC", or only one of the variety of subgenres. Therefore, it is not usually considered a specific genre of music; it is merely an assemblage of selected tracks from musicians of many different genres.
What is Christian AC a subgenre of?
****
The answer:
contemporary Christian music
