[EX Q]: Background Paragraph: For example, a radioactive isotope of iodine (I-131) is used in both the diagnosis and treatment of thyroid cancer. The thyroid will normally absorb some iodine to produce iodine-containing thyroid hormones. An overactive thyroid gland will absorb a larger amount of the radioactive material. If this is the case, more and more radioactive iodine can be administered, where it will cluster in the diseased portion of the thyroid tissue and kill some of the nearby cells. Cancer treatments often cause patients to feel very sick, because while the radiation treatment kills the unwanted cancer cells, it causes damage to some healthy cells in the process. 
Story: John is a doctor in a local hospital. Today, he is seeing two patients, patient A and patient B. Patient A has thyroid cancer, but patient B does not have thyroid cancer. John is trying to see the difference between these two patients' reports. 
Question: Which patient would have an overactive thyroid gland, patient A or patient B?
[EX A]: patient A.

[EX Q]: Background Paragraph: 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 iron—27 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. 
Story: 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. 
Question: Which woman's diet will most likely include less red meat?
[EX A]: Meredith.

[EX Q]: Background Paragraph: As time passes, the number of HIV copies keeps increasing, while the number of helper T cells keeps decreasing. The graph in Figure below shows how the number of T cells typically declines over a period of many years following the initial HIV infection. As the number of T cells decreases, so does the ability of the immune system to defend the body. As a result, an HIV-infected person develops frequent infections. Medicines can slow down the virus but not get rid of it, so there is no cure at present for HIV infections or AIDS. There also is no vaccine to immunize people against HIV infection, but scientists are working to develop one. 
Story: Robert and Justin are both patients in the hospital who are suffering complications from their HIV infections. The doctor is trying to get information from both men about their diseases so he can create customized treatment plans for both men. After a few questions, the doctor discovers that Robert has been infected with HIV for many years, while Justin's infection is quite recent. 
Question: Who will have a larger number of HIV copies in their body?
[EX A]:
Robert.
