input: Please answer the following: Please answer correctly the following question related to the paragraph below. Would test A increase or decrease the rate of reaction than test B? Rob wanted to learn more about collision theory. For that, he conducted two tests, test A and test B. In test A he used lower concentration of reactants. In test B he used higher concentration of reactants. Now, he needs to know about the science behind these tests. Hint: Collision theory tells us that molecules need to collide in order for a reaction to take place. All else being equal, anything that increases the frequency of collisions would also increase the rate of reaction. One way to do this is to increase the concentrations of one or more of the reactants. Using a real world example, a busy freeway will experience much more frequent car collisions than a fairly empty neighborhood street. Similarly, forcing more randomly moving molecules into the same amount of space will cause an increased number of collisions over a given length of time, providing the reactants with more opportunities to transform into products.

Please answer this: Please answer correctly the following question related to the paragraph below. Which group had fewer people that spend a lot of time playing at the computer? Two groups of people when to the doctor. Group A had myopia, while group B had nearsightedness. Both groups got eyeglasses for their conditions. Hint: Generally, nearsightedness first occurs in school-age children. There is some evidence that myopia is inherited. If one or both of your parents need glasses, there is an increased chance that you will too. Individuals who spend a lot of time reading, working or playing at a computer, or doing other close visual work may also be more likely to develop nearsightedness. Because the eye continues to grow during childhood, myopia typically progresses until about age 20. However, nearsightedness may also develop in adults due to visual stress or health conditions such as diabetes. A common sign of nearsightedness is difficulty seeing distant objects like a movie screen or the TV, or the whiteboard or chalkboard in school.

Problem: Please answer correctly the following question related to the paragraph below. Which camper learned less about air molecules moving faster? Two campers were in the woods over the week-end. They both had canned soup with them. Pete heated the can without venting it and it exploded, while Dan opened his can and heated it over the fire with no additional problems. Hint: It would be very unadvisable to place a can of soup over a campfire without venting the can. As the can heats up, it may explode. The kinetic-molecular theory explains why. The air inside the rigid can of soup is given more kinetic energy by the heat coming from the campfire. The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The increase in pressure inside may eventually exceed the strength of the can and it will explode. An additional factor is that the soup may begin boiling which will then aid even more gas and more pressure to the inside of the can.

A: Dan
Problem: Given the question: Please answer correctly the following question related to the paragraph below. Which country would have larger plant food supply for its indigenous animals, Nicaragua or Costa Rica? Both Nicaragua and Costa Rica had large tract of pristine forests. They had one of the largest concentration of tropical species. In the 1980s Nicaragua started clearing up some of these forests. Instead, they have now vast tract of sugarcane production in that land. One can still visit Costa Rica where they kept those pristine forests intact. Hint: Besides anthropogenic productivity of the land, the biodiversity of degraded land also declines, as previously mentioned.[12] With less biodiversity, this ecosystem is less adaptable to when disasters strike it[11][8] It has a smaller available food supply, in terms of plants, for animals, who then may die out or more likely may relocate. Proof of this decline is that presently 15-20% of Tibetan Plateau species are now considered endangered; and now because of this animal and plant absence, the soil quality of these degraded lands is very poor.[1] It does not hold the necessary nutrients, such as water, nitrogen, and carbon, essential to either supporting life or inviting life back to that land.[6] As a result of such carbon and nitrogen loss in the Tibetan Plateau, $8,033/ha and $13,315/ha were respectively lost in economic terms. Soils are further weakened by dust storms whose frequency increases because of degradation.[11][4] Erosion of soil becomes a bigger problem, since no longer are there as many plants to anchor in the soil. In the northern Chinese province alone, 400 million are affected every year with an associated 54 billion yuan of annual economic loss due to grassland degradation.

The answer is:
Costa Rica
input question: Please answer correctly the following question related to the paragraph below. Which camera would have lower f-number focusing lens, camera A or camera B? David needs to purchase a camera for his photography class. He went to the local consumer electronics store to find himself a good camera. Two cameras caught his eye, camera A and camera B. Camera A had a very small pinhole, but camera B had larger aperture. David needs to decide which camera should he buy. Hint: In practice, the diameter of the aperture is chosen based on the focal length of the lens, the diameter and quality of the input beam, and its wavelength (longer wavelengths require larger apertures). If the hole is too small, the beam quality is greatly improved but the power is greatly reduced. If the hole is too large, the beam quality may not be improved as much as desired. The size of aperture that can be used also depends on the size and quality of the optics. To use a very small pinhole, one must use a focusing lens with a low f-number, and ideally the lens should not add significant aberrations to the beam. The design of such a lens becomes increasingly more difficult as the f-number decreases.???
output answer: camera A
input question: Please answer correctly the following question related to the paragraph below. Which snake had more rattles, the first or the third snake Dan found? Dan found three rattle snakes: one only had one rattle, the second snake had 4 rattles and the third snake had seven rattles on its tail. Hint: At birth, a rattlesnake hatchling has only a small button or 'primordial rattle' which is firmly attached to the tip of the tail.[13] The first segment is added when the hatchling sheds its skin for the first time.[14] A new section is added each time the skin is shed until a rattle is formed. The rattle grows as the snake ages but segments are also prone to breaking off and hence the length of a rattle is not a reliable indicator of the age of a snake.[15]???
output answer:
the third
