Question: I read this background article the other day: Einstein showed in his thought experiments that people travelling at different speeds, while agreeing on cause and effect, measure different time separations between events, and can even observe different chronological orderings between non-causally related events. Though these effects are typically minute in the human experience, the effect becomes much more pronounced for objects moving at speeds approaching the speed of light. Subatomic particles exist for a well known average fraction of a second in a lab relatively at rest, but when travelling close to the speed of light they are measured to travel farther and exist for much longer than when at rest. According to the special theory of relativity, in the high-speed particle's frame of reference, it exists, on the average, for a standard amount of time known as its mean lifetime, and the distance it travels in that time is zero, because its velocity is zero. Relative to a frame of reference at rest, time seems to "slow down" for the particle. Relative to the high-speed particle, distances seem to shorten. Einstein showed how both temporal and spatial dimensions can be altered (or "warped") by high-speed motion. I am facing a new situation today: David wanted to test the theory of Einstein. To that end, he measured the time perceived by an airline pilot, who naturally traveled very fast. He labeled it as case A. To compare the pilot with a slower traveler he measured the time perceived by a semi truck driver covering the same distance. He labeled it as case B. He was amazed by the counter intuitive results he got from the experiment. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: According to Einstein, who would perceive "slow down" of time, case A or case B?
Answer: case A
[Q]: I read this background article the other day: Hypertension , which is also called "high blood pressure," occurs when a person's blood pressure is always high. Hypertension is said to be present when a person's systolic blood pressure is always 140 or higher, and/or if the person's diastolic blood pressure is always 90 or higher. Having hypertension increases a person's chance for developing heart disease, having a stroke, or suffering from other serious cardiovascular diseases. Hypertension often does not have any symptoms, so a person may not know that he or she has high blood pressure. For this reason, hypertension is often called the "silent killer." Treatments for hypertension include diet changes, exercise, and medication. Foods thought to lower blood pressure include skim milk, spinach, beans, bananas and dark chocolate. I am facing a new situation today: Dirk went to the doctor because he was feeling dizzy. The doc told him he has Hypertension. His wife, Mary went to the doctor the following week, and the doc said her blood pressure was normal. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which patient had high blood pressure?
****
[A]: Dirk
input: Please answer the following: I read this background article the other day: Rainfall in an area is important because it influences the rate of weathering. More rain means that more rainwater passes through the soil. The rainwater reacts chemically with the particles. The top layers of soil are in contact with the freshest water, so reactions are greatest there. High rainfall increases the amount of rock that experiences chemical reactions. High rainfall may also carry material away. This means that new surfaces are exposed. This increases the rate of weathering. I am facing a new situation today: Rob is an environmental scientist. He is looking at two samples of soil, sample A and sample B. Sample A is from Amazon Rain-forest, where they get one of the highest rainfall in the world. Sample B is from the Atacama Desert, where they get one of the lowest rainfall in the world. He needs to determine the properties of these samples. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which sample would show decreased rate of weathering, sample A or sample B?
++++++++++
output: sample B

I am facing a new situation today: Bill and Bob were two brothers. They were both pretty active, but Bill loved salty foods and red wine. He got dizzy one day and went to the doctor. Bill had hypertension. Bob, on the other hand was hypotensive. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which brother didn't have a diastolic blood pressure always always 90 or higher?
++++++++
Answer: Bob
input: Please answer the following: I read this background article the other day: Ionizing radiation has many practical uses in medicine, research and construction, but presents a health hazard if used improperly. Exposure to radiation causes damage to living tissue; high doses result in Acute radiation syndrome (ARS), with skin burns, hair loss, internal organ failure and death, while any dose may result in an increased chance of cancer and genetic damage; a particular form of cancer, thyroid cancer, often occurs when nuclear weapons and reactors are the radiation source because of the biological proclivities of the radioactive iodine fission product, iodine-131. However, calculating the exact risk and chance of cancer forming in cells caused by ionizing radiation is still not well understood and currently estimates are loosely determined by population based data from the atomic bombings of Hiroshima and Nagasaki and from follow-up of reactor accidents, such as the Chernobyl disaster. The International Commission on Radiological Protection states that "The Commission is aware of uncertainties and lack of precision of the models and parameter values", "Collective effective dose is not intended as a tool for epidemiological risk assessment, and it is inappropriate to use it in risk projections" and "in particular, the calculation of the number of cancer deaths based on collective effective doses from trivial individual doses should be avoided." I am facing a new situation today: Tom and Jerry are two friends who have always had competitions with one another throughout their whole lives. Yesterday, they just finished their most unique competition so far. Each man was given a room to sit in that had several highly radioactive objects in it. The challenge was to see who would stay in the chamber longer. Tom didn't stay in his room for very long, but Jerry felt determined to win and stayed in his chamber almost the entire day. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Who is less likely to need a liver transplant?

output:
Tom
