input: Please answer the following: David is a biologist. He was in the African savanna to study different species. Especially, he was interested in two species, rhinos and impalas. He noticed that in response to constant human encroachment of wildlife habitats, impalas have acquired some behaviors that help them and their young. Rhinos also have acquired some behaviors in response to the same threat. But their behaviors mostly failed them in that aspect. Would impalas have lower or higher chance of passing their genes on to the next generation than rhinos? Hint: All of these animal behaviors are important. They help the animals get food for energy, make sure their young survive, or ensure that they, themselves, survive. Behaviors that help animals or their young survive, increase the animals' fitness. Animals with higher fitness have a better chance of passing their genes on to the next generation. If genes control behaviors that increase fitness, the behaviors become more common in the species. This occurs through the process of evolution by natural selection.

Please answer this: As an economist Dan is interested in economies of South America. He has extensively studied two countries, Venezuela and Bolivia. His conclusion is Venezuela's economic policy had lead to capital flight. But Bolivia is a completely different story. Their economic policy did not lead to capital flight. Would Bolivia lose or retain confidence of the investors? Hint: Capital flight, in economics, occurs when assets or money rapidly flow out of a country, due to an event of economic consequence. Such events could be an increase in taxes on capital or capital holders or the government of the country defaulting on its debt that disturbs investors and causes them to lower their valuation of the assets in that country, or otherwise to lose confidence in its economic strength. This leads to a disappearance of wealth, and is usually accompanied by a sharp drop in the exchange rate of the affected countrydepreciation in a variable exchange rate regime, or a forced devaluation in a fixed exchange rate regime. This fall is particularly damaging when the capital belongs to the people of the affected country, because not only are the citizens now burdened by the loss in the economy and devaluation of their currency, but probably also, their assets have lost much of their nominal value. This leads to dramatic decreases in the purchasing power of the country's assets and makes it increasingly expensive to import goods and acquire any form of foreign facilities, e.g. medical facilities.

Problem: Rob was in the East Coast for a month. He had the good opportunity to see various tidal conditions. First he saw the spring tide, which he noted as case A. About a week later he saw the neap tide. He noted that as case B. Rob got curious about the science behind various tidal conditions. Which case would see stronger tidal currents, case A or case B? Hint: When the Moon is at first quarter or third quarter, the Sun and Moon are separated by 90 when viewed from the Earth, and the solar tidal force partially cancels the Moon's tidal force. At these points in the lunar cycle, the tide's range is at its minimum; this is called the neap tide, or neaps. Neap is an Anglo-Saxon word meaning "without the power", as in forganges nip (forth-going without-the-power).Spring tides result in high waters that are higher than average, low waters that are lower than average, 'slack water' time that is shorter than average, and stronger tidal currents than average. Neaps result in less extreme tidal conditions. There is about a seven-day interval between springs and neaps.

A: case A

Problem: Given the question: Two students studied chemistry. Nate studied alkanes, and Ben studied noble gasses. They both got an A later on. Which student learned less about ethane? Hint: Saturated hydrocarbons are given the general name of alkanes . The name of specific alkanes always ends in ane . The first part of the name indicates how many carbon atoms each molecule of the alkane has. The smallest alkane is methane. It has just one carbon atom. The next largest is ethane with two carbon atoms. The chemical formulas and properties of methane, ethane, and other small alkanes are listed in the Table below . The boiling and melting points of alkanes are determined mainly by the number of carbon atoms they have. Alkanes with more carbon atoms generally boil and melt at higher temperatures.

input question: Two coastal communities on two neighboring gulfs took different approaches to bringing more money into the local economy. Davin village continued with commercial fishing and agriculture, while the village of Forx decided to mine sand from the nearby dunes, because it was very profitable. They did not think about the effect it would have on the environment. Which village made more money by mining sand? Hint: Sand mining is a direct cause of erosion, and impacts the local wildlife.[2] Various animals depend on sandy beaches for nesting clutches, and mining has led to the near extinction of gharials (a species of crocodile) in India. Disturbance of underwater and coastal sand causes turbidity in the water, which is harmful for organisms like coral that need sunlight. It can also destroy fisheries, financially harming their operators. Removal of physical coastal barriers, such as dunes, sometimes leads to flooding of beachside communities, and the destruction of picturesque beaches causes tourism to dissipate. Sand mining is regulated by law in many places, but is often done illegally.[3] Globally, it is a $70 billion industry, with sand selling at up to $90 per cubic yard.[4]???

input question: Joe studied the lives of humans. He studied 2 groups of people. Group G had people over 65 in it, and group Y had people under 65 years old in it. Which group had more people that had decreased reflex time? Hint: Old age begins in the mid-60s and lasts until the end of life. Most people over 65 have retired from work, freeing up their time for hobbies, grandchildren, and other interests. Stamina, strength, reflex time, and the senses all decline during old age, and the number of brain cells decreases as well. The immune system becomes less efficient, increasing the risk of serious illnesses such as cancer and pneumonia. Diseases such as Alzheimer's disease that cause loss of mental function also become more common.???
output answer:
Group G
