Background: Greenhouse Effect: The solar energy reaching the surface of the Earth is concentrated in short wavelengths, which can easily penetrate the greenhouse gases, such as carbon dioxide and methane. The Earth, however, is cooler than the sun and it radiates its heat in the form of energy in the far infrared range. These longer wavelengths are partially absorbed by the greenhouse gases and some of the solar heat is returned to Earth. At a certain temperature these processes are in equilibrium and the surface temperature of the Earth is stable. However, if more greenhouse gases are put in the atmosphere the amount of trapped terrestrial radiation increases, leading to an increase in global temperature.  Paragraph: David was visiting the natural history museum. He noticed two charts that showed the climatic conditions of the earth in two time periods, time A and time B. Time A showed earth's overall climate in the sixteenth century when there were less greenhouse gases in the atmosphere. And time B showed earth's overall climate in the present century with more greenhouse gases in the atmosphere. David found some interesting differences between these two charts.  Given the paragraph above, please answer correctly the following question: Would global temperature in time A be higher or lower than time B's temperature?
----
Answer: lower


Background: A period of very low rainfall occurred while the Grants were on the islands. The drought resulted in fewer seeds for the finches to eat. Birds with smaller beaks could eat only the smaller seeds. Birds with bigger beaks were better off. They could eat seeds of all sizes. Therefore, there was more food available to them. Many of the small-beaked birds died in the drought. More of the big-beaked birds survived and reproduced. Within just a couple of years, the average beak size in the finches increased. This was clearly evolution by natural selection.  Paragraph: Two ancient continents both had a great bird population. At some point in time, the continent of MU experienced a great drought that lasted for several years. The other continent, Lemuria, was unaffected by the drought.  Given the paragraph above, please answer correctly the following question: Which continent had more seeds for the birds?
----
Answer: Lemuria


Background: Conifers have many uses. They are important sources of lumber and are also used to make paper. Resins, the sticky substance you might see oozing out of a wound on a pine tree, are collected from conifers to make a variety of products, such as the solvent turpentine and the rosin used by musicians and baseball players. The sticky rosin improves the pitcher’s hold on the ball or increases the friction between the bow and the strings to help create music from a violin or other stringed instrument.  Paragraph: Two neighboring towns, Pine town and Willow town, used different types of woods for lumber et al. Willow town used hardwoods, while Pine town used softwoods.  Given the paragraph above, please answer correctly the following question: Which town used more conifers for their sticky substance you might see oozing out of a wound on a pine tree?
