input question: I read this background article the other day: A comet tail—and coma—are features visible in comets when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus, carrying dust away with them. Separate tails are formed of dust and gases, becoming visible through different phenomena; the dust reflects sunlight directly and the gases glow from ionisation. Most comets are too faint to be visible without the aid of a telescope, but a few each decade become bright enough to be visible to the naked eye.  I am facing a new situation today: This year thee comets would be of interest, comet A, comet B, and comet C. Comet A and comet B would enter the inner solar system. But comet C would not enter the inner solar system. Moreover, comet A is categorized as a bright comet, but comet B is categorized as a faint comet.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which comet's tail would be visible from earth, comet A or comet C????
output answer: comet A

input question: I read this background article the other day: When humans dig up and use fossil fuels, we have an impact on the carbon cycle ( Figure below ). This carbon is not recycled until it is used by humans. The burning of fossil fuels releases more carbon dioxide into the atmosphere than is used by photosynthesis. So, there is more carbon dioxide entering the atmosphere than is coming out of it. Carbon dioxide is known as a greenhouse gas , since it lets in light energy but does not let heat escape, much like the panes of a greenhouse. The increase of greenhouse gasses in the atmosphere is contributing to a global rise in Earth’s temperature, known as global warming or global climate change.  I am facing a new situation today: Recently a large amount of factories have been built in Illinois using fossil fuels as their main energy source. In Indiana however, many of their factories have been shut down and replaced by parks with many plants and trees.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Given illinois decides to shut down half of the fossil fuel burning factories will carbon dioxide levels increase or decrease????
output answer: decrease

input question: I read this background article the other day: Candied fruit, also known as crystallized fruit or glacé fruit, has existed since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.[1] This process allows the fruit to retain its quality for a year.[2]  The continual process of drenching the fruit in syrup causes the fruit to become saturated with sugar, preventing the growth of spoilage microorganisms due to the unfavourable osmotic pressure this creates.[3]  I am facing a new situation today: Mary and Ann got some fruit as a gift from a friend. Mary decided to candy the fruit, while Ann decided to eat them fresh, Mary received plums, peaches, apples and oranges. Ann got pears, quince, cherries and blackberries.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit retained their quality longer apples or quince????
output answer: apples

input question: I read this background article the other day: For example, if a solid pellet of NaOH is placed into a chamber of HCl gas, a relatively slow acid-base reaction will occur between gaseous HCl molecules and hydroxide ions on the surface of the pellet. If we were to grind the pellet into smaller pieces, it would greatly increase the total surface area, and therefore the overall reaction rate. Once ground up, many hydroxide ions that were on the interior of the pellet, where they were not exposed to any HCl molecules, will now be on the surface, where the necessary collisions can occur.  I am facing a new situation today: In his chemistry lab David is experimenting with how NaOH and HCl gas reacts with each other. He conducted two experiments, experiment A and experiment B. In experiment A he used solid pellets of NaOH, but in experiment B he used ground NaOH. He was surprised to see the difference it made in his experiment.  Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would experiment A's hydroxide have smaller or larger surface area than experiment B's hydroxide????
output answer:
smaller
