Here is a question about this article: An article in Science suggested that the construction and filling of the Zipingpu Dam may have triggered the earthquake. The chief engineer of the Sichuan Geology and Mineral Bureau said that the sudden shift of a huge quantity of water into the region could have relaxed the tension between the two sides of the fault, allowing them to move apart, and could have increased the direct pressure on it, causing a violent rupture. The effect was "25 times more" than a year's worth of natural stress from tectonic movement. The government had disregarded warnings about so many large-scale dam projects in a seismically active area. Researchers have been denied access to seismological and geological data to examine the cause of the quake further.
What is the answer to this question: What was the affect of the dam on the stresses in that area?
****
So... 25 times more

The problem: Answer a question about this article:
To the east of the county are upland areas leading to the Pennines. North of the Ribble is Beacon Fell Country Park and the Forest of Bowland, another AONB. Much of the lowland in this area is devoted to dairy farming and cheesemaking, whereas the higher ground is more suitable for sheep, and the highest ground is uncultivated moorland. The valleys of the River Ribble and its tributary the Calder form a large gap to the west of the Pennines, overlooked by Pendle Hill. Most of the larger Lancashire towns are in these valleys South of the Ribble are the West Pennine Moors and the Forest of Rossendale where former cotton mill towns are in deep valleys. The Lancashire Coalfield, largely in modern-day Greater Manchester, extended into Merseyside and to Ormskirk, Chorley, Burnley and Colne in Lancashire.
What is most of the lowland in the county devoted to?
****
The answer: dairy farming and cheesemaking

Problem: Please answer a question about the following article about 2008 Sichuan earthquake:
All of the highways into Wenchuan, and others throughout the province, were damaged, resulting in delayed arrival of the rescue troops. In Beichuan County, 80% of the buildings collapsed according to Xinhua News. In the city of Shifang, the collapse of two chemical plants led to leakage of some 80 tons of liquid ammonia, with hundreds of people reported buried. In the city of Dujiangyan, south-east of the epicenter, a whole school collapsed with 900 students buried and fewer than 60 survived. The Juyuan Middle School, where many teenagers were buried, was excavated by civilians and cranes. Dujiangyan is home of the Dujiangyan Irrigation System, an ancient water diversion project which is still in use and is a UNESCO World Heritage Site. The project's famous Fish Mouth was cracked but not severely damaged otherwise.
How many highways leading into Wenchuan were damaged?
A: All of the highways

In the last two decades, photovoltaics (PV), also known as solar PV, has evolved from a pure niche market of small scale applications towards becoming a mainstream electricity source. A solar cell is a device that converts light directly into electricity using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. In 1931 a German engineer, Dr Bruno Lange, developed a photo cell using silver selenide in place of copper oxide. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery. Following the work of Russell Ohl in the 1940s, researchers Gerald Pearson, Calvin Fuller and Daryl Chapin created the crystalline silicon solar cell in 1954. These early solar cells cost 286 USD/watt and reached efficiencies of 4.56%. By 2012 available efficiencies exceed 20% and the maximum efficiency of research photovoltaics is over 40%.

Who created the first solar cell?
Answer: Charles Fritts

Problem: In Lithuania Propria and in Samogitia prior to the creation of the Kingdom of Lithuania by Mindaugas, nobles were named die beste leuten in sources that were written in German language. In the Lithuanian language nobles were named ponai. The higher nobility were named 'kunigai' or 'kunigaiksciai' (dukes)i.e., loanword from Scandinavic konung. They were the established local leaders and warlords. During the development of the state they gradually became subordinated to higher dukes, and later to the King of Lithuania. Because of expansion of Lithuanian duchy into lands of Ruthenia in the mid of 14th century a new term appeared to denominate nobility bajoraifrom Ruthenian (modern Ukrainian and Belarusian languages) . This word to this day is used in Lithuanian language to name nobility, not only for own, but also for nobility of other countries.
What were the higher nobility named?
The answer is the following: kunigai' or 'kunigaiksciai'

Input: Article: Greek cuisine is characteristic of the healthy Mediterranean diet, which is epitomized by dishes of Crete. Greek cuisine incorporates fresh ingredients into a variety of local dishes such as moussaka, stifado, Greek salad, fasolada, spanakopita and souvlaki. Some dishes can be traced back to ancient Greece like skordalia (a thick puree of walnuts, almonds, crushed garlic and olive oil), lentil soup, retsina (white or rose wine sealed with pine resin) and pasteli (candy bar with sesame seeds baked with honey). Throughout Greece people often enjoy eating from small dishes such as meze with various dips such as tzatziki, grilled octopus and small fish, feta cheese, dolmades (rice, currants and pine kernels wrapped in vine leaves), various pulses, olives and cheese. Olive oil is added to almost every dish.

Now answer this question: What is added to almost every dish in Greece?

Output:
Olive oil
