Question: Given the background: There is worldwide concern about the relationship between climate change and the use of fossil fuels. Many scientists believe that increased use of these fuels (in vehicles and other gas-powered equipment) has the potential to irreversibly damage our environment. In addition to the environmental concerns, supplies of fossil fuels are finite, and because they are non-renewable energy sources, we will eventually need alternatives. New developments in batteries and other energy storage devices are being explored to help deal with these issues. Electrochemical processes are at the heart of these new technologies.  and the situation: Two countries used different fuels as power sources for their activities. Alsacia used fossil fuels, while Lorena devised more advanced energy storage devices, therefore relying on electricity.  Answer the following question: Which country caused fewer environmental concerns?
Answer: Lorena

Question: Given the background: Just as there are good-quality grasses for putting greens, there are good-quality grasses for the fairway and rough. The quality of grass influences the roll of the ball as well as the ability of the player to "take a divot" (effectively, the ability to hit down into the ball, hitting the ball first, then hitting the turf and removing a portion of it as the club continues its arc). Fairways on prestigious tours, like the PGA Tour, are cut low. Mowing heights influence the play of the course. For example, the grass heights at U.S. Open events are alternated from one hole to the next in order to make the course more difficult. One example of this is the infamous roughs at U.S. Opens, which are often 3 to 5 inches high, depending on how close to the fairway or green the section of grass will be. This makes it difficult for a player to recover after a bad shot.  and the situation: The golf course at the Aurora Country Club cuts their grass to  2 1/2 inches high. The grass at the Augusta Country Club is cut to 4 inches. Sam likes more of a challenge when playing golf but Jack likes to play on turf where the ball rolls easier.  Answer the following question: Which Country Club would Sam enjoy playing golf at less, Aurora or Augusta?
Answer: Aurora

Question: Given the background: Alpine climate is the average weather (climate) for the alpine tundra. The climate becomes colder at high elevations—this characteristic is described by the lapse rate of air: air tends to get colder as it rises, since it expands. The dry adiabatic lapse rate is 10 °C per km (5.5 °F per 1000 ft) of elevation or altitude. Therefore, moving up 100 metres (330 ft) on a mountain is roughly equivalent to moving 80 kilometers (45 miles or 0.75° of latitude) towards the pole. This relationship is only approximate, however, since local factors such as proximity to oceans can drastically modify the climate.  and the situation: Two meteorologists study Earth's climate. Jerry studies alpine climate, while James studies tropical climates. They both made great progress.  Answer the following question: Which person observed that the climate becomes colder at high elevations?
Answer:
