I'm taking a test and have to guess the right answer to the question after the article. Article: Canadian scientists have found that the more emotional or mental challenges a person faces in a day, the less determined they become to work out physically. However, the findings should not stop us from keeping fit. Experts believe that willpower is like a muscle, and needs to be exercised to help one avoid the temptation spending a night on the couch instead. Kathleen Martin-Ginis, a professor of kinesiology-the science of movement--who led the study, says everyone has a limited amount of willpower, and that it will be reduced by stress. Miss Martin-Ginis, of Canada's McMaster University, explains," Cognitive tasks, as well as tasks such as regulating one's emotions, can reduce one's capacity to force oneself to exercise. " Her team of scientists performed a so-called "Stroop" test on volunteers to reach their conclusions. The experiment involved showing participants words associated with color1s but printed in different color1s-for example, the word "blue" written in red ink Participants were divided into two groups. One group was asked to name the color1 of the ink, instead to say the printed word, while the other wasn't Martin-Girus says, "After we used this cognitive task to use up their self-regulatory capacity, the participants didn't exercise as hard as those who had not performed the task " The more people concentrated on the cognitive task, the more likely they were to skip exercise sessions over the next eight week You only have so much willpower. However, there are ways to strengthen willpower. The study found the listening to music before going to the gym can help, as well as making a commitment to work out with friends. It also concluded that willpower can be stretched by constant cake, or forcing oneself to study an extra hour each night Martin- Ginis adds," There are strategies people can use to help revitalize themselves after they've used up their self-regulation Willpower is like a muscle: it needs to be used to stay strong. " Question: What can we infer from the passage? , Options: A: Will power can be challenged to become powerful. B: McMaster University is famous for its kinesiology. C: Effective ways to resist temptations have been found D: The study has an impact on the science of movement

I'm taking a test and have to guess the right answer to the question after the article. Article: I spend a lot of time backpacking and hiking the outdoors and there are two pieces of equipment that are with me on each trip: an Adventure Medical Kits Weekender and an Adventure Medical Kits Suture Syringe Kit. Both proved very helpful on my most recent adventures to the Wrangell in Alaska. On that day, we were "blessed" with rain, making our water crossing on the Dixie Pass very difficult. Our party of 12 had almost reached our destination when I slipped, severely gashing my knee open in the process. While I could not see the wound at first because of the rain pants I was wearing, I knew _ was severe. Blood was running freely and I made those standing nearby aware of the damage. They quickly came over to assist, pulled my pack off and removed the Weekender First Aid Kit and Suture Kit from it. Fortunately, one of my partners is a doctor called William, who has often performed this type of work in the operating room, not out in the wild. I seriously think he was more nervous about all this than me! I, of course, was more than happy that I did not have to stitch myself up. As a marine, I've had to do it before. Fortunately, the sky had cleared up about two hours before, so we had great sunlight to work with. The doctor worked quickly with the assistance of another fellow camper acting as a nurse and placed seven stitches into my knee once the wound had been cleaned up. Later that evening we used a syringe we set aside loaded with Iodine to clean the wound and then bandaged it again. The doctor was very impressed with the kits contents! I've already ordered another Suture Syringe Kit. I have to say the kits are worth their weight in gold! Thanks for the contents in the kits! Question: From the passage, we can infer that the kits are _ . Options: A: useless B: extremely useful C: troublesome D: not essential

I'm taking a test and have to guess the right answer to the question after the article. Article: Something's not quite right with the climate.While global CO2emissions have continued to swell, the global temperature rise has leveled off.Meanwhile, satellites and other observational tools indicate that the net heat retained by the planet has continued to increase, and that excess energy should be pushing up surface temperatures.But it's not. In fact, up to half the heat energy that was expected to fuel global wanning since 2003 has gone " missing.M Kevin Trenberth and John Fasullo of the National Center for Atmospheric Research ( NCAR) wonder where that heat may have gone--and what it could mean for the future of the climate. One possibility is that some of our measurements could be off.Although scientists have a lot of confidence in their ability to measure CO2buildup and the energy balance in the atmosphere--the data used in the measurements comes from multiple sources, all of which, Fasullo says, "tell the same story"--our data on ocean temperatures isn't as good."Keeping track of temperature over the whole oceans isn't that easy," says Fasullo. So, it is likely that the missing heat is being trapped deep in the ocean, well below the 900m to 1,500m range of our surface sensors.But despite their vastness, the deep oceans have a limit, says Fasullo, who thinks they won't behave as a heat sink over the long term."That's not what we've seen over long time scales in the past," he says."We clearly know the ocean can't absorb the heat indefinitely. Overall, the missing heat doesn't change expectations for future climate change, because the heat won't stay missing forever.Eventually it will resurface and impact the climate system, and the recent and deceptive reprieve from rapid warming we've enjoyed will come to an expected end.When that will happen is unknown, but better science can give us a clearer idea."At the end of the day, the system will come back to balance, and that suggests temperature will end up increasing," says Fasullo.So it's still up to us to do something about it. Question: Where is the missing heat likely to hide, as Fasullo expects? Options: A: It may hide in our natural environment. B: It has sunk into ocean over the long term. C: It may be absorbed by large number of forests. D: It may be absorbed by deep ocean temporarily.
