Input: Thuringia
Environmental damage in Thuringia has been reduced to a large extent after 1990. The condition of forests, rivers and air was improved by modernizing factories, houses (decline of coal heating) and cars, and contaminated areas such as the former Uranium surface mines around Ronneburg have been remediated. Today's environmental problems are the salination of the Werra river, caused by discharges of K+S salt mines around Unterbreizbach and overfertilisation in agriculture, damaging the soil and small rivers.

What is one thing that helped to improve condition of forests, rivers and air?
Output: modernizing factories

Input: Article: The modern English word green comes from the Middle English and Anglo-Saxon word grene, from the same Germanic root as the words "grass" and "grow". It is the color of living grass and leaves and as a result is the color most associated with springtime, growth and nature. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content.

Now answer this question: What, in nature, is most likely to make things green?

Output: chlorophyll

Here is a question about this article: According to the Sichuan Department of Commerce, the province's total foreign trade was US$22.04 billion in 2008, with an annual increase of 53.3 percent. Exports were US$13.1 billion, an annual increase of 52.3 percent, while imports were US$8.93 billion, an annual increase of 54.7 percent. These achievements were accomplished because of significant changes in China's foreign trade policy, acceleration of the yuan's appreciation, increase of commercial incentives and increase in production costs. The 18 cities and counties witnessed a steady rate of increase. Chengdu, Suining, Nanchong, Dazhou, Ya'an, Abazhou, and Liangshan all saw an increase of more than 40 percent while Leshan, Neijiang, Luzhou, Meishan, Ziyang, and Yibin saw an increase of more than 20 percent. Foreign trade in Zigong, Panzhihua, Guang'an, Bazhong and Ganzi remained constant.
What is the answer to this question: By how much did foreign trade increase in Sichuan in 2008?
****
So... 53.3 percent

The problem: Answer a question about this article:
There is disagreement about the origin of the term, but general consensus that "cardinalis" from the word cardo (meaning 'pivot' or 'hinge') was first used in late antiquity to designate a bishop or priest who was incorporated into a church for which he had not originally been ordained. In Rome the first persons to be called cardinals were the deacons of the seven regions of the city at the beginning of the 6th century, when the word began to mean "principal," "eminent," or "superior." The name was also given to the senior priest in each of the "title" churches (the parish churches) of Rome and to the bishops of the seven sees surrounding the city. By the 8th century the Roman cardinals constituted a privileged class among the Roman clergy. They took part in the administration of the church of Rome and in the papal liturgy. By decree of a synod of 769, only a cardinal was eligible to become pope. In 1059, during the pontificate of Nicholas II, cardinals were given the right to elect the pope under the Papal Bull In nomine Domini. For a time this power was assigned exclusively to the cardinal bishops, but the Third Lateran Council in 1179 gave back the right to the whole body of cardinals. Cardinals were granted the privilege of wearing the red hat by Pope Innocent IV in 1244.
What was it that gave cardinals the right to elect the pope?
****
The answer:
the Papal Bull In nomine Domini
