Question: I can use this background: When a solid substance is involved in a chemical reaction, only the matter at the surface of the solid is exposed to other reactants. If a solid has more surface area, more of it is exposed and able to react. Therefore, increasing the surface area of solid reactants increases the reaction rate. Look at the hammer and nails pictured in the Figure below . Both are made of iron and will rust when the iron combines with oxygen in the air. However, the nails have a greater surface area, so they will rust faster. Now, I have a new situation: John is trying to figure out how the shape of an object affects how it reacts with other elements. For that, he chose two objects, both made of the same element - object A and object B. Object A has a larger surface area, but object B has smaller surface area. He let these objects to react with other reactants to see how the processes work. Answer this question please: Which object would seem react slower, object A or object B?
Answer: object B
[Q]: I can use this background: Electronegativities generally increase from left to right across a period. This is due to an increase in nuclear charge. Alkali metals have the lowest electronegativities, while halogens have the highest. Because most noble gases do not form compounds, they do not have electronegativities. Note that there is little variation among the transition metals. Electronegativities generally decrease from top to bottom within a group due to the larger atomic size. Now, I have a new situation: John was studying the periodic table. To make things easier for him he divided the table in different sections, section A, section B, section C, and section D. Section A elements are located at the left of the table, but section B elements are located at the right side of the table. Section C elements are located at the top, but section D elements are located at the bottom. Answer this question please: Which elements would have less electronegativities, section A or section B?
****
[A]: section A
input: Please answer the following: I can use this background: 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. Now, I have a new situation: Sandra liked all creatures but loved to study frogs. Her sister Julie studied more about fish and butterflies. They both loved nature. Answer this question please: Which sister learned less about males attracting female frogs to the bodies of water for mating?
++++++++++
output: Julie
Please answer this: I can use this background: In exercises such as weight lifting, skeletal muscle contracts against a resisting force (see Figure below ). Using skeletal muscle in this way increases its size and strength. In exercises such as running, the cardiac muscle contracts faster and the heart pumps more blood. Using cardiac muscle in this way increases its strength and efficiency. Continued exercise is necessary to maintain bigger, stronger muscles. If you don't use a muscle, it will get smaller and weakerso use it or lose it. Now, I have a new situation: Bill and Bob were two brothers. they were both into physical exercise, but Bill chose weight lifting, and Bob running. Answer this question please: Which brother had more muscles contract against a resisting force?
++++++++
Answer: Bill
Problem: I can use this background: 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. Now, I have a new situation: John has been hearing about climate change for last couple of years. He wants to understand the science behind climate change. For that, he picked up two eras in earth's history, era A and era B. Era A was hundred thousand years ago, and era B is in the present day. He now wants to compare these to eras to understand the change in climate better. Answer this question please: Which era would have more autotrophic organisms, era A or era B?

A: era A
input: Please answer the following: I can use this background: About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which water erodes the limestone over thousands to millions of years. Most cave systems are through limestone bedrock. Now, I have a new situation: Peter visited two mountain ranges last summer. The Ozarks in Missouri, and the Colorado Rockies. He loved both ranges, but liked the caves systems and blue holes in the Ozarks a bit more. Answer this question please: Which mountains have more caves?
++++++++++
output:
Ozarks
