user: Please answer correctly the following question related to the paragraph below.   Whose muffins will spoil slower?  Sam and Jim are two bakers who both just finished baking a batch of muffins. They both baked more muffins than they needed, so they decided to store some of them for later. Sam decided to store his extra muffins in the refrigerator, where the temperature is relatively high. Jim instead decided to store his extra muffins in the freezer, where the temperature is relatively low.  Hint: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage.
Ans: Jim

Please answer correctly the following question related to the paragraph below.   Which Government took the right step to combat their currency being traded in the black market?  On March 2015 Japans economy soared. There was a likelihood that the Japanese yen would rise in value. In the wake of this event, Japanese Government adjusted  the price of Japanese Currency Yen in accordance with the going market price. On the other hand, at he same time, UK was having economic downturn. There was a likelihood that the UK Currency Pound Sterling would go down. Fearing public backlash, UK Government kept the price of the Pound Sterling at the same level.  Hint: 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]
Ans: Japanese Government

Please answer correctly the following question related to the paragraph below.   Which group had a fire that burned faster?  Two groups of scientists examined two fires. Group A put a large log on it, and group B made a fire with small twigs. They wanted to see which fire would last longer.  Hint: A large log placed in a fire will burn relatively slowly. If the same mass of wood were added to the fire in the form of small twigs, they would burn much more quickly. This is because the twigs provide a greater surface area than the log does. An increase in the surface area of a reactant increases the rate of a reaction. Surface area is larger when a given amount of a solid is present as smaller particles. A powdered reactant has a greater surface area than the same reactant as a solid chunk. In order to increase the surface area of a substance, it may be ground into smaller particles or dissolved into a liquid. In solution, the dissolved particles are separated from each other and will react more quickly with other reactants.
Ans: group B

Please answer correctly the following question related to the paragraph below.   Will Sam's grandfather have an increased or decreased chance of developing Alzheimer's disease?  Sam is going to visit his grandfather. His grandfather lives in a retirement home and can barely take care of himself anymore.  Hint: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn’t work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer’s disease.
