Input: Article: Many older buildings in certain areas of Boston are supported by wooden piles driven into the area's fill; these piles remain sound if submerged in water, but are subject to dry rot if exposed to air for long periods. Groundwater levels have been dropping, to varying degrees, in many areas of the city, due in part to an increase in the amount of rainwater discharged directly into sewers rather than absorbed by the ground. A city agency, the Boston Groundwater Trust, coordinates monitoring of groundwater levels throughout the city via a network of public and private monitoring wells. However, Boston's drinking water supply, from the Quabbin and Wachusett Reservoirs to the west, is one of the very few in the country so pure as to satisfy federal water quality standards without filtration.

Now answer this question: Lots of older buildings are supported by what?

Output: wooden piles

Here is a question about this article: Today, this term also refers to the doctrines and practices of the Reformed churches of which Calvin was an early leader. Less commonly, it can refer to the individual teaching of Calvin himself. The particulars of Calvinist theology may be stated in a number of ways. Perhaps the best known summary is contained in the five points of Calvinism, though these points identify the Calvinist view on soteriology rather than summarizing the system as a whole. Broadly speaking, Calvinism stresses the sovereignty or rule of God in all things — in salvation but also in all of life. This concept is seen clearly in the doctrines of predestination and total depravity.
What is the answer to this question: What is a brief description of Calvinism?
****
So... the sovereignty or rule of God in all things

Problem: Please answer a question about the following article about 2008 Summer Olympics torch relay:

 China: In China, the torch was first welcomed by Politburo Standing Committee member Zhou Yongkang and State Councilor Liu Yandong. It was subsequently passed onto CPC General Secretary Hu Jintao. A call to boycott French hypermart Carrefour from May 1 began spreading through mobile text messaging and online chat rooms amongst the Chinese over the weekend from April 12, accusing the company's major shareholder, the LVMH Group, of donating funds to the Dalai Lama. There were also calls to extend the boycott to include French luxury goods and cosmetic products. According to the Washington Times on April 15, however, the Chinese government was attempting to "calm the situation" through censorship: "All comments posted on popular Internet forum Sohu.com relating to a boycott of Carrefour have been deleted." Chinese protesters organized boycotts of the French-owned retail chain Carrefour in major Chinese cities including Kunming, Hefei and Wuhan, accusing the French nation of pro-secessionist conspiracy and anti-Chinese racism. Some burned French flags, some added Nazism's Swastika to the French flag, and spread short online messages calling for large protests in front of French consulates and embassy. The Carrefour boycott was met with anti-boycott demonstrators who insisted on entering one of the Carrefour stores in Kunming, only to be blocked by boycotters wielding large Chinese flags and hit by water bottles. The BBC reported that hundreds of people demonstrated in Beijing, Wuhan, Hefei, Kunming and Qingdao.
What French company was being boycotted?
A: Carrefour
