Background: Pollutants also affect the atmosphere through their contribution to global warming. Global warming is an increase in the Earth's temperature. It is thought to be caused mostly by the increase of greenhouse gases like carbon dioxide. Greenhouse gases can be released by factories that burn fossil fuels. Over the past 20 years, burning fossil fuels has produced about three-quarters of the carbon dioxide from human activity. The rest of the carbon dioxide in the atmosphere is there because of deforestation, or cutting down trees ( Figure below ). Trees absorb carbon dioxide during cellular respiration, so when trees are cut down, they cannot remove carbon dioxide from the air. Paragraph: Quebec recently removed a large area consisting primarily of forests in order to make room for a new housing development. On the other hand, Montreal recently finished planting a large amount of new trees as part of an environmental initiative project. Given the paragraph above, please answer correctly the following question: Which area will remove higher levels of carbon dioxide from the air, Montreal or Quebec?
Ans: Montreal

Background: If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls. This is because less vapor is needed to saturate the air, so vapor condenses as the temperature falls. In normal conditions, the dew point temperature will not be greater than the air temperature because relative humidity cannot exceed 100%.[4] Paragraph: Sam lived in Chicago for many years and experienced those high humidity days during the summer, the Indian summers in October and harsh and humid winters, so he decided to move to San Diego, in a warmer and much dryer climate. Given the paragraph above, please answer correctly the following question: Which city has more fog during summer?
Ans: Chicago

Background: Often, foreign exchange controls can result in the creation of black markets to exchange the weaker currency for stronger currencies. This leads to a situation where the exchange rate for the foreign currency is much higher than the rate set by the government, and therefore creates a shadow currency exchange market. As such, it is unclear whether governments have the ability to enact effective exchange controls.[1] Paragraph: Booneland changed their foreign exchange controls and Bradland didn't. The foreign currency got more expensive and they had problems with a shadow currency exchange. Bradland people were more cautious and less inclined to take risks, but didn't have those problems. Given the paragraph above, please answer correctly the following question: Which country had a fewer shadow market problems?
Ans: Bradland

Background: Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease. With the advent of faster travel, distance has less effect than it did in the past, except where places previously connected by now-abandoned railways, for example, have fallen off the beaten path. Advances in communications technology, such as telegraphs, telephones, broadcasting, and internet, have further decreased the effects of distance.[1] Paragraph: Two neighboring countries with similar economies, followed different political and economical agendas. Niger developed its infrastructure and communications technology, while Nigeria didn't. Given the paragraph above, please answer correctly the following question: Which country is more connected?
Ans: Niger
