Problem: I read this background article the other day: Millions of people in the world jog for exercise. For the most part, jogging can be a healthy way to stay fit. However, problems can also develop for those who jog in the heat. Excessive sweating can lead to electrolyte loss that could be life-threatening. Early symptoms of electrolyte deficiency can include nausea, fatugue, and dizziness. If not treated, individuals can experience muscle weakness and increased heart rate (which could lead to a heart attack). Many sports drinks can be consumed to restore electrolytes quickly in the body.  I am facing a new situation today: Two teams of runners took part in a study about exercise. Red team ran 10 km in the heat, while Green team ran the same distance in the morning in cool weather. The Red team experienced more runners with health problems.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which team had fewer runners with nausea?

A: Green


Problem: I read this background article the other day: A few insects, such as mayflies and some moths, never eat. That’s because their lives are over in just a few hours or days. Once these insects become adults, they lay eggs, and then die. On the other hand, some insects are very healthy eaters. A silkworm eats enough leaves to increase its weight more than 4,000 times in just 56 days, as the silkworm increases in size about 10,000 times since birth. A locust eats its own weight in plants every day. Just imagine eating your own weight in food every day. You probably couldn't. You would most likely get very sick even if you tried.  I am facing a new situation today: Two agricultural students had to prepare for exams. Jane had the entomology exam, so she studied about insects. Nora had the chemistry exam, so she studied about alkanes.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student learned more about insects that never eat?

A: Jane


Problem: I read this background article the other day: Some Chinese martial arts instructors focus more on their qinna techniques than others. This is one of the many reasons why the qinna of one school may differ from that of another.[2] All martial arts contain qinna techniques in some degree. The southern Chinese martial arts have more developed qinna techniques than northern Chinese martial systems. The southern martial arts have much more prevalent reliance on hand techniques which causes the practitioner to be in closer range to their opponent. There are over 700 qinna traditional techniques found in all martial arts. In the Non-Temple White Crane style there are 150-200 qinna techniques alone. Along with Fujian White Crane, styles such as Northern Eagle Claw (Ying Jow Pai) and Tiger Claw (Fu Jow Pai) have qinna as their martial focus and tend to rely on these advanced techniques.  I am facing a new situation today: There is a long history of martial arts competition in Fujian Province of China. Interestingly, one can also place bets on competitors. David is a martial arts enthusiast, watching every martial arts movie he can find. This year David and his friend John is visiting the Fujian Province to see the martial arts competition. There are two rounds of competition, round A and round B. Round A competitors would display southern Chinese martial arts while round B competitors would display northern Chinese martial arts.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would round A see competitors closer or farther to their opponents?

A: closer


Problem: 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: Two farmers had different pests attacking their plants. John had a big aphid problem, so he used all the methods available to get rid of them.  Mike had a slug problem, but had almost no aphides.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which farmer didn't learn that aphids are resistant to organophosphates?

A:
Mike
