[Q]: I read this background article the other day: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis. I am facing a new situation today: Angela just bent through a really bad breakup and is feeling very depressed. To make herself feel better she tends to binge on foods that happen to be very high in lipids. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will a high fat diet increase or decrease lipid levels in the blood?
****
[A]: increase
input: Please answer the following: I read this background article the other day: Ecologically, the expansion of drainage systems has had tremendous negative effects. Hundreds of thousands of wetland species experienced significant population declines as their habitat was increasingly fragmented and destroyed. Although market hunting within the Central Flyway was a contributing factor in the decline of many waterfowl species' numbers in the early decades of the twentieth century, loss of breeding habitat to agricultural expansion is certainly the most significant. Early maps of midwestern states depict many lakes and marshes that are either nonexistent or significantly reduced in area today. Channelization, a related process of concentrating and facilitating the flow of water from agricultural areas, also contributed to this degradation. I am facing a new situation today: Both Alabama and Florida boast great wetlands. The State of Alabama has experienced extensive drainage system due to expansion of farmlands. Their neighboring state Florida had similar system. But recently Florida had dismantled many of their drainage systems, mostly because of pressure from different environmental groups. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which state would have declining waterfowl species, Florida or Alabama?
++++++++++
output: Alabama
Please answer this: I read this background article the other day: Clouds on Earth are made of water vapor. Venus's clouds are a lot less pleasant. They are made of carbon dioxide, sulfur dioxide and large amounts of corrosive sulfuric acid! The atmosphere of Venus is so thick that the pressure on the surface of Venus is very high. In fact, it is 90 times greater than the pressure at Earth's surface! The thick atmosphere causes a strong greenhouse effect. As a result, Venus is the hottest planet. Even though it is farther from the Sun, Venus is much hotter even than Mercury. Temperatures at the surface reach 465C (860F). That's hot enough to melt lead! I am facing a new situation today: Two students were learning about atmospheres and planets. Dan learned about the atmosphere of Earth, while Nate learned about planet Venus and its atmosphere. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned less about the planet with a hotter surface temperature?
++++++++
Answer: Dan
Problem: I read this background article the other day: Old age begins in the mid-60s and lasts until the end of life. Many people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common. I am facing a new situation today: Dr. Smith studied a group of people under 65 called group I, and a group of people over 65 called group II. Old age signs were more obvious after the age of 65. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which had more people freeing up their time for grandchildren?

A: group II
Problem: Given the question: I read this background article the other day: Storing large volumes of data When storing XML to either file or database, the volume of data a system produces can often exceed reasonable limits, with a number of detriments: the access times go up as more data is read, CPU load goes up as XML data takes more power to process, and storage costs go up. By storing XML data in Fast Infoset format, data volume may be reduced by as much as 80 percent. I am facing a new situation today: Bob works for a data storage company. He has now three projects, project A, project B, and project C, simultaneously going on. All of them involves storing XML data. Project A has small volume of data, but project B and project C has large volume of data. He applied Fast Infoset format for project B, but didn't apply that format for project C. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would project A have higher or lower access times compared to project C?
++++++++++++++++++++++++++++++++
The answer is:
lower access times
Problem: I read this background article the other day: Circadian rhythms are regular changes in biology or behavior that occur in a 24-hour cycle. In humans, for example, blood pressure and body temperature change in a regular way throughout each 24-hour day. Animals may eat and drink at certain times of day as well. Humans have daily cycles of behavior, too. Most people start to get sleepy after dark and have a hard time sleeping when it is light outside. In many species, including humans, circadian rhythms are controlled by a tiny structure called the biological clock . This structure is located in a gland at the base of the brain. The biological clock sends signals to the body. The signals cause regular changes in behavior and body processes. The amount of light entering the eyes helps control the biological clock. The clock causes changes that repeat every 24 hours. I am facing a new situation today: Jason is an average guy who goes to work each day, lives in an apartment, exercises sometimes, goes out and drinks some weekends and just generally enjoys life. Brad, however, has chosen to live in a dark cave that has no windows. He lives in a cave that has almost no light except for some candles he lights from time to time. If he needs food or supplies, he pays someone to go get them, and they slide them through a hole that can open in the steel door at the entrance of the cave. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is more likely to eat meals at the same time each day?

A:
Jason
