Problem: Geologists have been contemplating on the question - why some places are more susceptible to earthquakes. To understand the differences, they have made a chart where they divided the earth into two regions, region A and region B. In region A many earthquakes happen, but in region B no earthquakes happen. Given the paragraph above, please answer correctly the following question: Which region is most likely near a plate boundary, region A or region B? Hint: Almost all earthquakes occur at plate boundaries. All types of plate boundaries have earthquakes. Convection within the Earth causes the plates to move. As the plates move, stresses build. When the stresses build too much, the rocks break. The break releases the energy that was stored in the rocks. The sudden release of energy is an earthquake. During an earthquake the rocks usually move several centimeters. Rarely, they may move as much as a few meters. Elastic rebound theory describes how earthquakes occur ( Figure below ).

A: region A

Problem: Bob and Andy were two nature enthusiasts. They went camping together once a month. Bob was into bird watching, while Andy was fascinated with frogs and salamanders. They went on a trip last week-end and they were very happy with what they had observed. Given the paragraph above, please answer correctly the following question: Which friend observed more male frogs grabbing female frogs and squeezing them around the abdomen? Hint: You may hear males "ribbiting," producing a mating call used to attract females to the bodies of water best for mating and breeding. Frog calls can occur during the day or night. Each frog species has a different call that is used to attract mates and warn off rivals. When a female picks a male whose call she likes, the male grabs her and squeezes across her back and around her abdomen. This causes the female to release her eggs. The male then fertilizes the eggs and, in some species, also guards them.

A: Andy

Problem: Two cousins went to college to get a B.S. Greg studied Biology, and his younger cousin Dawn decided to study chemistry. They both graduated Summa Cum Laudae. Given the paragraph above, please answer correctly the following question: Which cousin studied more about the way chemists look at the world? Hint: Chemists look at the world in two ways, often simultaneously. The two worlds of the chemist are the macroscopic world and the microscopic world. Macroscopic refers to substances and objects that can be seen, touched, and measured directly. Microscopic refers to the small particles that make up all matter. Chemists must observe matter and do experiments macroscopically and then make generalizations and propose explanations that are microscopic in nature. For example, anyone can observe the physical change in appearance that occurs as an iron object such as a tractor that is left out in the elements gradually turns to rust. However, a chemist looks at the rusting tractor and thinks about what is going on with the individual atoms that make up the iron and how they are changing as a result of exposure to oxygen in the air and water from rain. Throughout your study of chemistry, you will often switch back and forth between the macroscopic and microscopic worlds.

A: Dawn

Problem: Mary and Ann are mother and daughter. Mary is in her 70's while Ann is in her late 40's. They both work out regularly for improved health. Mary has been experiencing some health issues lately. Given the paragraph above, please answer correctly the following question: Which person is at a higher risk of developing Alzheimer's disease? 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.
