Problem: I have a new situation: Because of the weed and insect menace villagers from North village decided to use herbicide tolerant crops. South village decided to postpone a decision and kept using regular seeds. But I can use this background: In addition to insects, weeds have also been a menace to farmers - just ask anyone with a garden how much they hate weeds. They can quickly compete for water and nutrients needed by other plants. Sure, farmers can use herbicides to kill weeds, but do these chemicals also harm the crops? Can biotechnology help with this issue? Some crops have also been genetically engineered to acquire tolerance to the herbicides - allowing the crops to grow, but killing the weeds. But the lack of cost effective herbicides with a broad range of activity - that do not harm crops - is a problem in weed management. Multiple applications of numerous herbicides are routinely needed to control the wide range of weeds that are harmful to crops. And at times these herbicides are being used as a preventive measure that is, spraying to prevent weeds from developing rather than spraying after weeds form. So these chemicals are being added to crops. This practice is followed by mechanical and/or hand weeding to control weeds that are not controlled by the chemicals. Crops that are tolerant of herbicides would obviously be a tremendous benefit to farmers ( Figure above ). The introduction of herbicide tolerant crops has the potential to reduce the number of chemicals needed during a growing season, thereby increasing crop yield due to improved weed management and decreased harm to the crops. What is an answer for this question: Which village didn't increase their crop yield?

A: South
Problem: Given the question: I have a new situation: Kenya's Masai Mara wildebeest migration is one of the greatest spectacles in the natural world. Every year thousands of wildebeests cross the Mara river. John went to see the migration last year. He noticed that the wildebeests crossed the the river in a very large group. He noted that as case A. His guide told him that is not the case in other times of the year. The wildebeests cross the river in smaller groups in other times. John noted that as case B. The guide added that in both cases on thing is constant, they are attacked by the lions. But I can use this background: A dilution effect is seen when animals living in a group "dilute" their risk of attack, each individual being just one of many in the group. George C. Williams and W.D. Hamilton proposed that group living evolved because it provides benefits to the individual rather than to the group as a whole, which becomes more conspicuous as it becomes larger. One common example is the shoaling of fish. Experiments provide direct evidence for the decrease in individual attack rate seen with group living, for example in Camargue horses in Southern France. The horse-fly often attacks these horses, sucking blood and carrying diseases. When the flies are most numerous, the horses gather in large groups, and individuals are indeed attacked less frequently. Water striders are insects that live on the surface of fresh water, and are attacked from beneath by predatory fish. Experiments varying the group size of the water striders showed that the attack rate per individual water strider decreases as group size increases. What is an answer for this question: In which case an individual wildebeest would get less benfit, case A or case B?

The answer is:
case B
input question: I have a new situation: An inventor named Nelly is tinkering around in her home office where she has created two new types of material that could be used in products. The first one she is calling Glubber, and the second she has named Malk. To try to figure out what type of products these new materials may be used for, Nelly is performing various tests. The first test she is doing is securing one end of the material to a table and then pulling on it and letting it go. When she performs this test on some Glubber, the material quickly snaps back toward the table. Performing the same process with some Malk, the material slowly crawls along the floor as it makes its way back to the table. But I can use this background: Something that is elastic can return to its original shape after being stretched or compressed. This property is called elasticity . As you stretch or compress an elastic material like a bungee cord, it resists the change in shape. It exerts a counter force in the opposite direction. This force is called elastic force . The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape. You can watch a demonstration of elastic force at this URL: What is an answer for this question: Which material is more resistant to changing shape????
output answer: Glubber
[Q]: I have a new situation: Susan went to the store to buy some bags of ice for a party she was having later in the day. When she got home she put one bag of ice in the sink and another in the freezer, but then was distracted by a phone call and forgot to put the other bag in the freezer. When she returned, the bag of ice had melted. Thomas is a research assistant and has taken samples of rat liver enzymes that need to be stored overnight. He places one in refrigerated storage, but forgot one and left it out on the counter top. But I can use this background: Temperature is a measure of the average kinetic energy of the particles in matter. In everyday usage, temperature indicates a measure of how hot or cold an object is. Temperature is an important parameter in chemistry. When a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased. Many unstable materials (such as enzymes) will be viable longer at lower temperatures. What is an answer for this question: Will the sample on the counter have a lower or higher average kinetic energy than the refrigerated sample?
