input 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: Will project C incur higher or lower storage cost than porject A????
output answer: higher

input question: I read this background article the other day: Insecticide control of aphids is difficult, as they breed rapidly, so even small areas missed may enable the population to recover promptly. Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. Finally, some aphid species are resistant to common insecticide classes including carbamates, organophosphates, and pyrethroids.For small backyard infestations, spraying plants thoroughly with a strong water jet every few days may be sufficient protection. An insecticidal soap solution can be an effective household remedy to control aphids, but it only kills aphids on contact and has no residual effect. Soap spray may damage plants, especially at higher concentrations or at temperatures above 32 C (90 F); some plant species are sensitive to soap sprays. I am facing a new situation today: Bill and Jane are two farmers. They both had aphid infestation problems over the last few years, so Bill decided to use many types of insecticides in order to keep the aphids under control. He was only partially successful. Jane didn't do anything about it yet, because she has fewer aphids on her farm, but she vows to do so in the near future. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer had more aphids resistant to organophosphates????
output answer: Bill

input question: I read this background article the other day: Unfortunately, the layer of good ozone is being destroyed by air pollution. The chief culprits are chlorine and bromine gases. They are released in aerosol sprays, coolants, and other products. Loss of ozone has created an ozone hole over Antarctica. Ozone depletion results in higher levels of UV radiation reaching Earth. In humans, this increases skin cancers and eye cataracts. It also disturbs the nitrogen cycle, kills plankton, and disrupts ocean food webs. The total loss of the ozone layer would be devastating to most life. Its rate of loss has slowed with restrictions on pollutants, but it is still at risk. I am facing a new situation today: Planet Y and planet X were two inhabited planets in a nearby solar system. People from Planet X were living in harmony with nature, and didn't hurt the environment in any way. People on planet Y generated lots of air pollution, and destroyed their ozone layer by using inappropriate substances. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which planet didn't alter their nitrogen cycle????
output answer: planet X

input question: I read this background article the other day: The device in the circuit in Figure above is an ammeter. It measures the current that flows through the wire. The faster the magnet or coil moves, the greater the amount of current that is produced. If more turns were added to the coil, this would increase the strength of the magnetic field as well. If the magnet were moved back and forth repeatedly, the current would keep changing direction. In other words, alternating current would be produced. This is illustrated in Figure below . I am facing a new situation today: James is testing the strength of electromagnetic fields. He takes two lengths of copper wire and coils them. His first coil, A, has a weaker magnetic field than his second coil, B. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Given a very stong current is flowing through a wire, will an ammeter connected to the wire's magnet move fast or slow????
output answer:
fast
