Please answer this: I read this background article the other day: In the U.S., the majority of electricity is produced by burning coal or other fossil fuels. This causes air pollution that harms the health of living things. The air pollution also causes acid rain and contributes to global warming. In addition, fossil fuels are nonrenewable resources, so if we keep using them, they will eventually run out. The main advantage of nuclear energy is that it doesn't release air pollution or cause the other environmental problems associated with the burning of fossil fuels. On the other other hand, radioactive elements are nonrenewable like fossil fuels and could eventually be used up. I am facing a new situation today: Canada produced its electricity by using fossil fuels and nuclear fission. New Zealand used only alternative, renewable sources to produce their electricity. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which country used more renewable resources?
++++++++
Answer: New Zealand
Problem: I read this background article the other day: However, the addition of a metal catalyst, such as platinum, provides a lower energy pathway. The energy requirements for breaking the H-H bond are offset somewhat if each hydrogen atom can form a new bond with the metal surface. Then, collisions between the alkene and the metal-hydrogen complex result in the formation of a product. The metal surface is regenerated after the hydrogen atoms are removed, so it is not used up by the reaction, but it increases the rate by stabilizing the high energy hydrogen atoms. I am facing a new situation today: Michael and Robert are both performing a chemistry experiment. The reaction they are performing uses alkenes and hydrogen as reactants. Michael performs the experiment without any additional materials, while Robert performs the experiment while using a platinum catalyst. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Whose reaction will require less energy to occur?

A: Robert
Problem: Given the question: I read this background article the other day: From the data he collected and documented, Aristotle inferred quite a number of rules relating the life-history features of the live-bearing tetrapods (terrestrial placental mammals) that he studied. Among these correct predictions are the following. Brood size decreases with (adult) body mass, so that an elephant has fewer young (usually just one) per brood than a mouse. Lifespan increases with gestation period, and also with body mass, so that elephants live longer than mice, have a longer period of gestation, and are heavier. As a final example, fecundity decreases with lifespan, so long-lived kinds like elephants have fewer young in total than short-lived kinds like mice. I am facing a new situation today: John wanted to revisit Aristotle's theory of tetrapods. To that end, he chose two tetrapods, tetA and tetB. An adult tetA was heavier than an adult tetB. Moreover, a tetA had longer gestation period than tetB. He needed to figure out how their characteristics fit Aristotle's theory. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which tetrapod would have smaller brood size, tetA or tetB?
++++++++++++++++++++++++++++++++
The answer is:
tetA
input question: I read this background article the other day: Animals and some bacteria and fungi carry out lactic acid fermentation. Lactic acid is a waste product of this process. Our muscles perform lactic acid fermentation during strenuous exercise, since oxygen cannot be delivered to the muscles quickly enough. The buildup of lactic acid is believed to make your muscles sore after exercise. Bacteria that produce lactic acid are used to make cheese and yogurt. The lactic acid causes the proteins in milk to thicken. Lactic acid also causes tooth decay, because bacteria use the sugars in your mouth for energy. I am facing a new situation today: Two students had to study fermentation processes for a school project. Ned studied lactic fermentation, while Kat studied alcoholic fermentation. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student read more about fungi carrying out lactic acid fermentation????
output answer: Ned
I read this background article the other day: Beginning in the late 1970's, ozone depletion was recognized as a significant environmental issue. The most dramatic decrease in ozone occurs seasonally over the continent of Antarctica. The size and duration of the ozone hole steadily increased, with the largest hole recorded in 2006. Fortunately, most countries have recognized the danger of CFCs and dramatically curtailed their use in recent years. It is hoped that ozone depletion will slow and that the ozone layer may eventually be restored to its earlier levels. I am facing a new situation today: Factories around the world produce lots of CFCs which deplete the ozone layer. One year a large number of these factories decided they would implement efforts to reduce the amount of CFCs they release into the atmosphere. As a result the depletion of the ozone layer greatly decreased. However, the companies realized that this was hurting profits too much and reverted their decision. As a result the ozone layer began to rapidly deplete again. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Will the ozone layer deplete faster or slower if more companies that emit CFCs are built?

Answer: more
Q: I read this background article the other day: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies. I am facing a new situation today: A female goose now has a large family of chicks, the chicks mostly fend for themselves and can move around almost immediately after being born. A short way away a female dog gives birth to a litter of puppies. These on the other hand are defenseless, cant really move and are blind. They require extensive care from their mother. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which animal, the baby geese or the puppies, is an altricial species of animal?
A:
puppies
