Please answer this: I read this background article the other day: Individuals living in large groups may be safer from attack because the predator may be confused by the large group size. As the group moves, the predator has greater difficulty targeting an individual prey animal. The zebra has been suggested by the zoologist Martin Stevens and his colleagues as an example of this. When stationary, a single zebra stands out because of its large size. To reduce the risk of attack, zebras often travel in herds. The striped patterns of all the zebras in the herd may confuse the predator, making it harder for the predator to focus in on an individual zebra. Furthermore, when moving rapidly, the zebra stripes create a confusing, flickering motion dazzle effect in the eye of the predator. I am facing a new situation today: Two packs of lions were hunting large herbivores. The Simba pack was ambushing wounded individual prey animals, while the Mobutu pack followed large groups of zebras and other grazers. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which pack was confused less often by the striped patterns of the zebras?

Answer: Simba

Please answer this: I read this background article the other day: Candied fruit, also known as crystallized fruit or glace fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2] The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3] I am facing a new situation today: John enrolled in a prestigious culinary school. In the very first day his instructor was showing different processes used on fruits. One of them was glace fruit. He showed the class how to prepare glace fruit and kept some of the glace fruits on bowl A. To compare glace fruits with non glace fruits he kept some non glace fruits on bowl B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruits had most probably not gone through heated sugar syrup, bowl A or bowl B?
++++++++
Answer: bowl B

Please answer this: I read this background article the other day: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. I am facing a new situation today: Two medical school students named Dan and Bob learned about the human immune system. Dan studied more about the subject, and became very interested to pursue it more in the future. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned that the infected skin area may become painful?
++++++++
Answer:
Dan
