Here is a question about this article: Plant responses to climate and other environmental changes can inform our understanding of how these changes affect ecosystem function and productivity. For example, plant phenology can be a useful proxy for temperature in historical climatology, and the biological impact of climate change and global warming. Palynology, the analysis of fossil pollen deposits in sediments from thousands or millions of years ago allows the reconstruction of past climates. Estimates of atmospheric CO2 concentrations since the Palaeozoic have been obtained from stomatal densities and the leaf shapes and sizes of ancient land plants. Ozone depletion can expose plants to higher levels of ultraviolet radiation-B (UV-B), resulting in lower growth rates. Moreover, information from studies of community ecology, plant systematics, and taxonomy is essential to understanding vegetation change, habitat destruction and species extinction.
What is the answer to this question: How can climate changes be determined from soil?
****
So... fossil pollen deposits in sediments

The problem: Answer a question about this article:
On St. George's Night (Estonian: Jurioo ulestous) 23 April 1343, the indigenous Estonian population in the Duchy of Estonia, the Bishopric of Osel-Wiek and the insular territories of the State of the Teutonic Order tried to rid themselves of the Danish and German rulers and landlords, who had conquered the country in the 13th century during the Livonian crusade, and to eradicate the non-indigenous Christian religion. After initial success the revolt was ended by the invasion of the Teutonic Order. In 1346 the Duchy of Estonia was sold for 19,000 Koln marks to the Teutonic Order by the King of Denmark. The shift of sovereignty from Denmark to the State of the Teutonic Order took place on 1 November 1346.
What event ended the uprising?
****
The answer: the invasion of the Teutonic Order.

Problem: Please answer a question about the following article about Cotton:
In addition to concerns over subsidies, the cotton industries of some countries are criticized for employing child labor and damaging workers' health by exposure to pesticides used in production. The Environmental Justice Foundation has campaigned against the prevalent use of forced child and adult labor in cotton production in Uzbekistan, the world's third largest cotton exporter. The international production and trade situation has led to "fair trade" cotton clothing and footwear, joining a rapidly growing market for organic clothing, fair fashion or "ethical fashion". The fair trade system was initiated in 2005 with producers from Cameroon, Mali and Senegal.
What type of labor have some countries come under fire for employing?
A: child

By spring 1950, Stalin believed the strategic situation had changed. The Soviets had detonated their first nuclear bomb in September 1949; American soldiers had fully withdrawn from Korea; the Americans had not intervened to stop the communist victory in China, and Stalin calculated that the Americans would be even less willing to fight in Koreawhich had seemingly much less strategic significance. The Soviets had also cracked the codes used by the US to communicate with the US embassy in Moscow, and reading these dispatches convinced Stalin that Korea did not have the importance to the US that would warrant a nuclear confrontation. Stalin began a more aggressive strategy in Asia based on these developments, including promising economic and military aid to China through the SinoSoviet Friendship, Alliance, and Mutual Assistance Treaty.

Where did Stalin engage in an aggressive political strategy?
Answer: Asia

Problem: In 1998, Apple introduced its new iMac which, like the original 128K Mac, was an all-in-one computer. Its translucent plastic case, originally Bondi blue and later various additional colors, is considered an industrial design landmark of the late 1990s. The iMac did away with most of Apple's standard (and usually proprietary) connections, such as SCSI and ADB, in favor of two USB ports. It replaced a floppy disk drive with a CD-ROM drive for installing software, but was incapable of writing to CDs or other media without external third-party hardware. The iMac proved to be phenomenally successful, with 800,000 units sold in 139 days. It made the company an annual profit of US$309 million, Apple's first profitable year since Michael Spindler took over as CEO in 1995. This aesthetic was applied to the Power Macintosh and later the iBook, Apple's first consumer-level laptop computer, filling the missing quadrant of Apple's "four-square product matrix" (desktop and portable products for both consumers and professionals). More than 140,000 pre-orders were placed before it started shipping in September, and by October proved to be a large success.
What did the iMac replace most of Apple's standard connections with?
The answer is the following: two USB ports

Input: Article: Draught beer's environmental impact can be 68% lower than bottled beer due to packaging differences. A life cycle study of one beer brand, including grain production, brewing, bottling, distribution and waste management, shows that the CO2 emissions from a 6-pack of micro-brew beer is about 3 kilograms (6.6 pounds). The loss of natural habitat potential from the 6-pack of micro-brew beer is estimated to be 2.5 square meters (26 square feet). Downstream emissions from distribution, retail, storage and disposal of waste can be over 45% of a bottled micro-brew beer's CO2 emissions. Where legal, the use of a refillable jug, reusable bottle or other reusable containers to transport draught beer from a store or a bar, rather than buying pre-bottled beer, can reduce the environmental impact of beer consumption.

Now answer this question: What beer is better for the environment than bottled beer?

Output:
Draught beer's
