Problem: Please answer correctly the following question related to the paragraph below. Which may not use average atmospheric conditions, term A or term B? David was interested in climate change issues. He realized that to understand climate change issues he first needed to distinguish between the terms weather and climate. To that end, he labeled weather as term A. Then he labeled climate as term B. He found it easier to understand their differences in that way. Hint: Weather is a set of all the phenomena occurring in a given atmospheric area at a given time. Most weather phenomena occur in the troposphere, just below the stratosphere. Weather refers, generally, to day-to-day temperature and precipitation activity, whereas climate is the term for the average atmospheric conditions over longer periods of time. When used without qualification, "weather" is understood to be the weather of Earth.

A: term A

Problem: Please answer correctly the following question related to the paragraph below. Who ordered colder water? Steve and Chris sit down at a new cafe that just opened up in town after hearing rave reviews of it at work. They look at the menus trying to decide what to order when a waiter shows up and asks if they would like anything to drink. Steve says he would like a glass of water that has molecules far apart. Chris orders water with molecules closer together. The waiter looks at them with a rather confused look and asks them to please elaborate. Hint: Liquid water is a fluid. The hydrogen bonds in liquid water constantly break and reform as the water molecules tumble past one another. As water cools, its molecular motion slows and the molecules move gradually closer to one another. The density of any liquid increases as its temperature decreases. For most liquids, this continues as the liquid freezes and the solid state is denser than the liquid state. However, water behaves differently. It actually reaches its highest density at about 4C.

A: Chris

Problem: Please answer correctly the following question related to the paragraph below. Which county is using a unit mesured with pound and inch, Germany or United States? John is a world traveler. Recently, he visited two countries, France and Germany. He noticed that in France they use atmosphere and Pascal as pressure units. In Germany they use torr as a pressure unit. Back in the United States, he noticed psi is used as a pressure unit. He needs to figure out how they correlate with each other. Hint: Pressures are given in a multitude of units. We've already discussed Pascals, and we know that another unit for pressure is the atmosphere (1 atm = 101.3 x 10 5 Pa). The third commonly used pressure unit is the torr (symbol Torr). 760 torr is 1 atm, but 1 torr is also the increase in pressure necessary to cause liquid mercury to rise by 1 mm. For that reason, torr is also commonly referred to as "millimeters mercury." Another pressure unit commonly used in our everyday world is psi, or pounds per square inch, though neither psi nor torr are SI units.

A: United States

Problem: Please answer correctly the following question related to the paragraph below. Which container of milk has less lactic acid? Tony and Greg are brothers. They are currently in the kitchen eating a snack together. Greg is eating a stalk of celery while Tony is eating out of a bowl of candy. Tony remarks that he doesn't know how Greg enjoys such a bland snack. Greg just gives Tony an angry glare before getting up to go into the living room. On the living room table, Greg finds a glass of milk and a bowl of milk. The glass of milk has started to get thick, but the bowl of milk appears to be still fresh. Greg rolls his eyes at the mess and walks away. Hint: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy.
