[Q]: You are given a new situation: Keith is a physician with the city hospital. He noticed that reactions inside human body happen in different rates. He specifically noticed two cases, case A and case B. In case A enzymes were present, but in case B enzymes were not present. and a hint : Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. One way this can happen is modeled in the Figure below . Enzymes aren't changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again. Each enzyme is highly specific for the particular reaction is catalyzes, so enzymes are very effective. A reaction that would take many years to occur without its enzyme might occur in a split second with the enzyme. Enzymes are also very efficient, so waste products rarely form. Please answer this question : Would the rate of chemical reactions be higher or lower in case B than in case A?
****
[A]: lower

input: Please answer the following: You are given a new situation: Two biologists studied different living creatures. Matt studied protozoa, while his friend Greg studied nematodes and insects. and a hint : Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms. Please answer this question : Which friend studied more about herbivore protozoa?
++++++++++
output: Matt

Please answer this: You are given a new situation: 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. and a hint : 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. Please answer this question : Will project A incur higher or lower storage cost than porject C?
++++++++
Answer: lower storage cost

Problem: You are given a new situation: Two bakeries were famous in town for their angel food cakes. Tom's was a small bakery with various small ovens, took small orders and did some catering. Bill's bakery was large and produced angel food cake commercially, in vast quantities. and a hint : In a bakery, angel food cakes could be baked in a rack oven, revolving oven, convention oven, or small deck oven. A commercial bakery may use a tunnel or traveling oven.[7] When the cake has finished baking, it should have a golden brown color on the exposed area.[5] The final volume will generally be two to three times larger than the batter volume.[6] Please answer this question : Which bakery used a tunnel oven to bake angel food cakes?

A: Bill's

Problem: Given the question: You are given a new situation: Rob is studying medicine in a prestigious university. Today, his professor is teaching about blood glucose levels. He gave example of two patients, patient A and patient B. Patient A had high blood glucose level, but patient B had low blood glucose level. Rob was amazed to find how body keeps its balance. and a hint : Another example of negative feedback has to do with blood glucose levels. When glucose (sugar) levels in the blood are too high, the pancreas secretes insulin to stimulate the absorption of glucose and the conversion of glucose into glycogen, which is stored in the liver. As blood glucose levels decrease, less insulin is produced. When glucose levels are too low, another hormone called glucagon is produced, which causes the liver to convert glycogen back to glucose. Please answer this question : Which patient would convert glycogen to glucose, patient A or patient B?
++++++++++++++++++++++++++++++++
The answer is:
patient B

Problem: You are given a new situation: Archaeologists studied data about human settlements. One was 100,000 years old called village R, and the other one was about 9,000 years old called village N. The older settlement was located in Africa, the other one wasn't. and a hint : The earliest members of the human species evolved around 200,000 years ago in Africa. Early humans lived in small populations of nomadic hunters and gatherers. Human beings remained in Africa until about 40,000 years ago. After that, they spread throughout Europe, Asia, and Australia. By 10,000 years ago, the first human beings colonized the Americas. During this long period of time, the total number of human beings increased very slowly. Birth rates were fairly high but so were death rates, producing low rates of population growth. Please answer this question : Which village had more people that were hunters?

A:
village R
