input question: Jeremy is performing some chores around the kitchen when he decides to pour himself some water into a blue cup. However, this water isn't cold enough so he puts it into the freezer to cool it down. He then pours himself the exact same amount of water in a red cup, but gets a phone call and leaves that cup on the table without taking a sip. He comes back two hours later after the phone call to get his cups of water back. Will the water in the red or blue cup have less volume? Hint: This is how ice wedging works. When liquid water changes into solid ice, it increases in volume. You see this when you fill an ice cube tray with water and put it in the freezer. The ice cubes go to a higher level in the tray than the water. You also may have seen this if you put a can of soda into the freezer so that it cools down quickly. If you leave the can in the freezer too long, the liquid expands so much that it bends or pops the can. (For the record, water is very unusual. Most substances get smaller when they change from a liquid to a solid.)???
output answer: red

input question: In the ant world a war has been waged. Two rival groups of Acromyrmex heyeri ants, group A and group B, are battling each other to gain territory. The goal is to attack the rival group when they have more openings in their nest thatch. In battle day one group A territory had 5 C temperature. In battle day two group A territory had 22 C temperature. In battle day three group A territory had low air humidity. In battle day four group A territory had high air humidity. In battle day four would group A have less openings or more openings in their nest thatch? Hint: Acromyrmex heyeri is a species of leaf-cutter ant, a New World ant of the subfamily Myrmicinae of the genus Acromyrmex. Acromyrmex heyeri workers construct the colonies nest by thatching together cut grass. At temperatures ranging from 2030 C, workers created more openings in the nest thatch as the internal nest temperature goes up as a method of temperature regulation for the colony. The workers will close openings in the nest thatch as the air humidity surrounding the nest decreases to reduce water loss for the colony.???
output answer: more openings

input question: Brett and Scott were both studying bacteria for their exam. Scott read more about nitrogen-fixating and sulfate-reducing bacteria, while his colleague Brett read more about non-respiratory anaerobe bacteria and facultative anaerobes. Which student read more about the production of the highly toxic dimethylmercury? Hint: In many ways, bacterial metabolism provides traits that are useful for ecological stability and for human society. One example is that some bacteria have the ability to fix nitrogen gas using the enzyme nitrogenase. This environmentally important trait can be found in bacteria of most metabolic types listed above. This leads to the ecologically important processes of denitrification, sulfate reduction, and acetogenesis, respectively. Bacterial metabolic processes are also important in biological responses to pollution; for example, sulfate-reducing bacteria are largely responsible for the production of the highly toxic forms of mercury (methyl- and dimethylmercury) in the environment. Non-respiratory anaerobes use fermentation to generate energy and reducing power, secreting metabolic by-products (such as ethanol in brewing) as waste. Facultative anaerobes can switch between fermentation and different terminal electron acceptors depending on the environmental conditions in which they find themselves.???
output answer: Scott

input question: Ben and Jerry were two friends with very different dietary habits. Jerry ate healthy food, and was always on top of his caloric consumption, while Ben overate because he loved fatty foods such as butter, bacon et al. Which friend didn't eat excess dietary lipids? Hint: Although some lipids in the diet are essential, excess dietary lipids can be harmful. Because lipids are very high in energy, eating too many may lead to unhealthy weight gain. A high-fat diet may also increase lipid levels in the blood. This, in turn, can increase the risk for health problems such as cardiovascular disease. The dietary lipids of most concern are saturated fatty acids, trans fats, and cholesterol. For example, cholesterol is the lipid mainly responsible for narrowing arteries and causing the disease atherosclerosis.???

Jerry
