Problem: Given the background: 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. and the situation: Kevin and his cousin Darlene both enjoy jogging for exercise. One day, Kevin goes out for a jog in his local neighborhood when the amount of heat outside is quite high, and he begins to sweat a lot and starts to feel a bit dizzy. On the same day, Darlene goes jogging in her neighborhood when the amount of heat outside is low and she feels perfectly normal as she continues to jog. Answer the following question: Who needs to consume a sports drink more urgently?

A: Kevin

Problem: Given the background: 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. and the situation: 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. Answer the following question: Which farmer had fewer aphids resistant to pyrethroids?

A: Jane

Problem: Given the background: Increases in erosion due to farming and other operations will be reflected by changes in sediment composition and increases in deposition rates elsewhere. In land areas with a depositional regime, engineered structures will tend to be buried and preserved, along with litter and debris. Litter and debris thrown from boats or carried by rivers and creeks will accumulate in the marine environment, particularly in coastal areas. Such manmade artifacts preserved in stratigraphy are known as "technofossils."Changes in biodiversity will also be reflected in the fossil record, as will species introductions. An example cited is the domestic chicken, originally the red junglefowl Gallus gallus, native to south-east Asia but has since become the world's most common bird through human breeding and consumption, with over 60 billion consumed a year and whose bones would become fossilized in landfill sites. Hence, landfills are important resources to find "technofossils". and the situation: Mike is an an archeologist. He was pondering about how human legacy would be viewed in the future. For that, he was very interested in technofossils. He located a site with ample evidence of technofossils. He noted that site as site A. To compare site A with a site with no technofossils he located another site. He noted that site as site B. Answer the following question: Would site A see less or more litter and debris depostied than site B?

A: more

Problem: Given the background: Often, foreign exchange controls can result in the creation of black markets to exchange the weaker currency for stronger currencies. This leads to a situation where the exchange rate for the foreign currency is much higher than the rate set by the government, and therefore creates a shadow currency exchange market. As such, it is unclear whether governments have the ability to enact effective exchange controls.[1] and the situation: Booneland changed their foreign exchange controls and Bradland didn't. The foreign currency got more expensive and they had problems with a shadow currency exchange. Bradland people were more cautious and less inclined to take risks, but didn't have those problems. Answer the following question: Which country had a more expensive foreign currency?

A:
Booneland
