Please answer this: I read this background article the other day: A person with a serious brain injury usually suffers permanent brain damage. These brain injuries usually occur when an external mechanical force, such as a violent blow or jolt to the head or body, causes brain dysfunction. An object penetrating the skull, such as a bullet or a shattered piece of the skull, also can cause traumatic brain injury. As a result, the person may have trouble talking or controlling body movements. Symptoms depend on what part of the brain was injured. Serious brain injuries can also cause personality changes and problems with mental abilities such as memory. Medicines, counseling, and other treatments may help people with serious brain injuries recover from, or at least learn to cope with, their disabilities. I am facing a new situation today: Tammy and Rob rode a tandem bike down the hill. They hit a large rock and fell. Tammy wound up in the hospital and was diagnosed with a serious brain injury. Rob suffered only a mild concussion. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which person had fewer problems with mental abilities?
++++++++
Answer: Rob
Problem: I read this background article the other day: Many people enjoy riding in hot air balloons. Some use them for romantic picnics and marriage proposals. Others race in competitions. Being above the earth gives a whole new perspective on the world around us. As the beginning of a hot air balloon ride, the balloon is flat because the pressure inside the balloon equals the pressure outside. When the air inside the balloon is heated, the speed of movement of those air molecules increases and the pressure goes up. After a while the balloon is completely expanded and the flight is ready to take off. I am facing a new situation today: Bob just came from a hot air balloon ride. On his way home he saw two balloons, balloon A and balloon B. Balloon A was flat, but balloon B was inflated. He was wondering how balloons go up so effortlessly. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Would balloon B have higher or lower inside pressure than balloon A?

A: higher
Problem: Given the question: I read this background article the other day: Boys and girls between the ages of 9 and 13 should get 9 mg of iron every day. Girls between the ages of 14 and 18 should get 15 mg of iron every day. Boys between the ages of 14 and 18 should get 11 mg of iron every day. Pregnant women need the most iron27 mg daily. Good sources of iron include shellfish, such as clams and oysters. Red meats, such as beef, are also a good source of iron. Non-animal sources of iron include seeds, nuts, and legumes. Breakfast cereals often have iron added to them in a process called fortification. Some good sources of iron are listed below ( Table below ). Eating vitamin C along with iron-containing food increases the amount of iron that the body can absorb. I am facing a new situation today: Phyllis and Meredith have the exact same diet and are both going to see a dietician for suggestions about what they should eat. Phyllis is currently five months pregnant and wants to see if she should do anything differently in regards to her food consumption. Meredith is not pregnant, but still wants to go to see if her diet is acceptable. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which woman's diet will most likely include more red meat?
++++++++++++++++++++++++++++++++
The answer is:
Phyllis
input question: I read this background article the other day: One result of air pollution is acid rain. Acid rain is precipitation with a low (acidic) pH. This rain can be very destructive to wildlife. When acid rain falls in forests, freshwater habitats, or soils, it can kill insects and aquatic life. It causes this damage because of its very low pH. Sulfur oxides and nitrogen oxides in the air both cause acid rain to form ( Figure below ). Sulfur oxides are chemicals that are released from coal-fired power plants. Nitrogen oxides are released from motor vehicle exhaust. I am facing a new situation today: Hydrologists studied two samples of rain water. Jim studied an acid rain sample from a nearby city, and Dan studied a sample of water from another town. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which hydrologist learned less about precipitation with a low (acidic) pH????
output answer: Dan
I read this background article the other day: Candied fruit, also known as crystallized fruit or glace 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: Helen got lots of different fruit as a gift from a friend that owned an orchard. She received apples, pears, apricots, peaches, plums, quince, among others. She decided to candy apples, apricots, and pears, and to keep the others fresh for as long as possible. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which fruit lasted longer, apricots or quince?
----
Answer: apricots
Q: I read this background article the other day: Many chemicals that were once commonly used were later found out to be harmful to the environment , to human health, or both. The element lead was once a common additive to gasoline and to paint. Plumbing pipes were once typically made of lead. Only since the 1970s has the danger of lead become apparent. It causes brain damage and small children (who often chewed on objects painted with lead-based paint) are particularly susceptible. The use of lead in gasoline, paint, and plumbing pipes is now banned and new materials are being developed to replace the hazardous lead components. I am facing a new situation today: Tim and Jeb were both studying chemical engineering. At a certain point in time, Jeb started studying chemicals that are not harmful for the environment, while Tim started learning about chemicals that were once used, but now are known to be harmful for the environment. Using the knowledge I acquired from the background article, how should I answer correctly the following question regarding my new situation: Which student studied more about the use of lead?
A:
Tim
