Input: Consider Input: Background Paragraph: Chlamydia may cause a burning feeling during urination. It may also cause a discharge (leaking of fluids) from the vagina or penis. But in many cases it causes no symptoms. As a result, people do not know they are infected, so they don’t go to the doctor for help. If chlamydia goes untreated, it may cause more serious problems in females. It may cause infections of the uterus, fallopian tubes, or ovaries. These infections may leave a woman unable to have children. 
Story: Two women are at an STD clinic getting tested because they feel they may have caught something from recent sexual partners they had. After getting a blood sample taken, Beth is told that she has genital herpes. The doctor tells her what to expect and how to manage the symptoms. The doctor then goes into the waiting room that Sarah is in and informs her that she has tested positive for chlamydia. Sarah is not surprised, and she begins asking questions about what she should do to help control the disease. 
Question: Who is less likely to experience an infection in their fallopian tubes?

Output: Beth.


Input: Consider Input: 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.

Lastly, he categorized pregnant women as cat D. He needs to recommend healthy diet, especially iron intake, for each group.

Input: Consider Input: Background Paragraph: All fluids exert pressure like the air inside a tire. The particles of fluids are constantly moving in all directions at random. As the particles move, they keep bumping into each other and into anything else in their path. These collisions cause pressure, and the pressure is exerted equally in all directions. When particles are crowded together in one part of an enclosed space, such as the air particles first entering a tire, they quickly spread out to fill all the available space. That’s because particles of fluids always move from an area of higher pressure to an area of lower pressure. This explains why air entering a tire through a tiny opening quickly fills the entire tire. 
Story: Catherine is throwing her friend a birthday party and is starting to put up decorations. She has finished hanging streamers and now she has to fill the balloons. Having never used a helium tank before, she wants to test how much to fill each balloon.

Output: decreased.
