input question: Sandra liked all creatures but loved to study frogs. Her sister Julie studied more about fish and butterflies. They both loved nature. Given the paragraph above, please answer correctly the following question: Which sister learned more about males attracting female frogs to the bodies of water for mating? Hint: You may hear males "ribbiting," producing a mating call used to attract females to the bodies of water best for mating and breeding. Frog calls can occur during the day or night. Each frog species has a different call that is used to attract mates and warn off rivals. When a female picks a male whose call she likes, the male grabs her and squeezes across her back and around her abdomen. This causes the female to release her eggs. The male then fertilizes the eggs and, in some species, also guards them.???

Michael and his brother John are making protein shakes. They are mixing different sizes of protein powder into the shakes to see if that impacts how the powder dissolves into the shake. Michael makes his shake using large individual pieces of protein powder, while John makes his shake using small individual pieces of powder. Given the paragraph above, please answer correctly the following question: Whose shake will have more easily dissolved protein powder? Hint: Mechanical weathering increases the rate of chemical weathering. As rock breaks into smaller pieces, the surface area of the pieces increases. With more surfaces exposed, there are more places for chemical weathering to occur ( Figure below ). Let's say you wanted to make some hot chocolate on a cold day. It would be hard to get a big chunk of chocolate to dissolve in your milk or hot water. Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk. This is because the smaller the pieces are, the more surface area they have. Smaller pieces dissolve more easily.

Q: Two students studied animal behavior for the biology class. Ned studied more about predators, while Kim studied more about herbivores. Given the paragraph above, please answer correctly the following question: Which student learned less about rabbits? Hint: Predators play an important role in an ecosystem. For example, if they did not exist, then a single species could become dominant over others. Grazers on a grassland keep grass from growing out of control. Predators can be keystone species . These are species that can have a large effect on the balance of organisms in an ecosystem. For example, if all of the wolves are removed from a population, then the population of deer or rabbits may increase. If there are too many deer, then they may decrease the amount of plants or grasses in the ecosystem. Decreased levels of producers may then have a detrimental effect on the whole ecosystem. In this example, the wolves would be a keystone species.

Question: Scientists studied two island. One with an old ecosystem named Old island, and the other with a newly formed and forming ecosystem named New island. Both islands were inhabited, Old island being heavily inhabited. Given the paragraph above, please answer correctly the following question: Which island had a less stable ecosystem factoring in the population? Hint: Ecology is the study of ecosystems. An ecosystem consists of all the living and nonliving components of the habitat. Whereas nutrients and certain elements are recycled through ecosystems, energy moves in just one direction. Many interactions among species within an ecosystem are centered around the flow of energy. The formation of ecosystems, from new land to current habitats, is usually based on the pioneer species, and these species are able to live in an area due to the nonliving factors, such as the climate, the soil and the amount of rainfall, of that area. The populations within an ecosystem also determine the stability of the system. Recent tremendous increases in the human population have raised many important ecological issues.
Answer: Old
[Q]: Two cities had different energy source. Big city burned fossil fuels, while Blue city used alternative sources of energy. Given the paragraph above, please answer correctly the following question: Which city produced more carbon dioxide? Hint: Because of human activities, there is more carbon dioxide in the atmosphere today than in the past hundreds of thousands of years. Burning fossil fuels and has released great quantities of carbon dioxide into the atmosphere. Cutting forests and clearing land has also increased carbon dioxide into the atmosphere because these activities reduce the number of autotrophic organisms that use up carbon dioxide in photosynthesis. In addition, clearing often involves burning, which releases carbon dioxide that was previously stored in autotrophs.

Problem: Given the question: John is a scientist. Yesterday, he conducted several tests, test A, test B, test C, test D, test E, and test F. In test A he kept a substance in solid state. Then in test B he changed the same substance to liquid state. In test C he conducted a chemical reaction in room temperature. Then in test D he conducted the same chemical reaction in higher temperature. In test E he kept some enzymes in high temperature. Finally, in test F he kept the same enzymes in lower temperature. Given the paragraph above, please answer correctly the following question: Which test would see lower temperature, test A or test B? Hint: 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.
