Problem: I can use this background: During sexual reproduction, mating with a close relative (inbreeding) often leads to inbreeding depression. Inbreeding depression is considered to be largely due to expression of deleterious recessive mutations. The effects of inbreeding have been studied in many vertebrate species. Now, I have a new situation: Keith is a zoologist. He studies large predators. Last year, he was studying different species of lions. First, he visited the Gir forest in India. There he found the Asiatic Lions. Unfortunately, only few Asiatic Lions are left in the wild, and they have to mate with their close relatives. He then visited the Serengeti reserve in Tanzania. There he found that the African Lions were not forced to mate with close relatives due to their large number. Answer this question please: Which lion species would be less prone to inbreeding, Asiatic or African?

A: African
Problem: Given the question: I can use this background: Alpine tundra occurs at high enough altitude at any latitude. Portions of montane grasslands and shrublands ecoregions worldwide include alpine tundra. Large regions of alpine tundra occur in the North American Cordillera, the Alps and Pyrenees of Europe, the Himalaya and Karakoram of Asia, the Andes of South America, and the Eastern Rift mountains of Africa.Alpine tundra occupies high-mountain summits, slopes, and ridges above timberline. Aspect plays a role as well; the treeline often occurs at higher elevations on warmer equator-facing slopes. Because the alpine zone is present only on mountains, much of the landscape is rugged and broken, with rocky, snowcapped peaks, cliffs, and talus slopes, but also contains areas of gently rolling to almost flat topography.Averaging over many locations and local microclimates, the treeline rises 75 metres (245 ft) when moving 1 degree south from 70 to 50N, and 130 metres (430 ft) per degree from 50 to 30N. Between 30N and 20S, the treeline is roughly constant, between 3,500 and 4,000 metres (11,500 and 13,100 ft). Now, I have a new situation: Gill and Ann were two fellow botanists. Gill studied alpine tundras extensively, while Ann studied tropical forests. They both discovered very interesting facts about nature and plants. Answer this question please: Which person learned more about rocky, snowcapped peaks?
++++++++++++++++++++++++++++++++
The answer is:
Gill
input question: I can use this background: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun. Now, I have a new situation: Keith is a doctor at the city hospital. Today, he is seeing six patients, patient A, patient B, patient C, patient D, patient E, and patient F. Patient A is a smoker, but patient B is not a smoker. Patient C uses sunscreen, but patient D does not use any sunscreen. Patient E tans with tanning lamps, but patient F tans in the sun. Answer this question please: Would patient E more likely or equally likely to risk skin cancer as patient F????
output answer: equally likely
I can use this background: One of the most common chromosome abnormalities is Down syndrome , due to nondisjunction of chromosome 21 resulting in an extra complete chromosome 21, or part of chromosome 21 ( Figure below ). Down syndrome is the only autosomal trisomy where an affected individual may survive to adulthood. Individuals with Down syndrome often have some degree of mental retardation, some impairment of physical growth, and a specific facial appearance. With proper assistance, individuals with Down syndrome can become successful, contributing members of society. The incidence of Down syndrome increases with maternal age. The risk of having a child with Down syndrome is significantly higher among women age 35 and older. Now, I have a new situation: Norm and Ian were two brothers. Norm was a totally normal individual, while Ian had Down syndrome. Their parents loved them both equally. Answer this question please: Which brother had an extra complete chromosome 21?
----
Answer: Ian
Q: I can use this background: Gasoline-powered vehicles emit a lot of harmful materials. Nitrogen oxides are formed when atmospheric nitrogen reacts with oxygen at the high temperatures found in a car engine. Carbon monoxide is a by-product of incomplete combustion of hydrocarbons. Evaporated and unused fuel releases volatile hydrocarbons into the atmosphere to help form smog. The presence of a catalytic converter in the exhaust system of the car causes these materials to react and be changed into less harmful products. Now, I have a new situation: Blue island and Red island were two big sister islands situated 100 miles from each other. People on Blue island used gas powered vehicles, while people on Red island used electrical vehicles. The people on Blue island presented more respiratory problems. Answer this question please: Which island emitted fewer harmful materials?
A: Red
[Q]: I can use this background: Human beings invented agriculture about 10,000 years ago. This provided a bigger, more dependable food supply. It also allowed people to settle down in villages and cities for the first time. Birth rates went up because there was more food and settled life had other advantages. Death rates also rose because of crowded living conditions and diseases that spread from domestic animals. Because the higher birth rates were matched by higher death rates, the human population continued to grow very slowly. Now, I have a new situation: Brad studied ancient human settlements from 100,000 years ago. His colleague Phil studied human settlement from 8-10,000 years ago. They were both fascinated by their findings. Answer this question please: Which colleague didn't study that more people settled down in cities?
****
[A]:
Brad
