Aid workers have worried that residents of the Eastern Gobi Refugee Camp might be at risk for beriberi, a severe deficiency of Thiamine, a B vitamin. Thiamine is found in high concentrations in cereal grains, and many of the residents have grain free diets because of allergies. Doctors and nutritionists assigned to investigate the situation have disagreed, noting that the residents grow sustenance amounts of potatoes, kale, and cauliflower on the surrounding farm lands, and these foods provide substantial sources of Thiamine as well. Because the residents of this refugee camp do not have any allergies to any of these latter foods, and crops have been good because of favorable weather conditions, their risk of beriberi is much lower than originally thought.In the argument given, the two portions in boldface play which of the following roles?

Locust swarms have ravaged much of Suwathia, resulting in the loss of vital agriculture. A multinational company has recently proposed using metarhizium, a fungus that invades the exoskeleton of the locust, causing a swift death. The government of Suwathia argues that the one means of application of metarhizia—from an airplane—will require a great amount of the fungus, which is difficult to acquire. Given that the locusts propagate rapidly, the government maintains that only a complete annihilation of a locust swarm will have the desired effect.Which of the following, if true, best argues in favor of the multinational company’s plan to drop metarhizium over locust swarms?

At HappyDay farms, seasonal staff is employed to pick apples during the harvest season each year. This staff is trained to identify and select only high quality apples, table-worthy apples. As part of this process, apples that have been visibly damaged by insects or disease are left to rot in the fields. The farmer who owns the property and sells the fruit is, therefore, less well informed about potential problems with his crops, such as insect infestations, than are the pickers themselves.The conclusion drawn above is based on the assumption that

The study found that the more rapid the response the higher that person’s IQ. Which of the following is an assumption the cognitive psychologist makes?
