You are given a background paragraph that describes one or more causal or qualitative relationships such as a relationship in economics or a scientific law and a story that makes use of the concepts or the relationship described in the provided paragraph. You need to come up with a question about the story that requires an understanding of the relationship described in the background paragraph. The generated question should not be answerable without both the background and story. Write a question about the story that requires a relationship in the background paragraph to answer. Check whether your question requires both the background paragraph and the story to answer. If your question can be answered by only one of these, try to rewrite your question so that it requires both. Note that "flipping" a word in the question can give rise to a new question where the answer will be different from the original question. Often, "flipping" a word gives rise to flipping the direction of the relationship, for example, from "increase" to "decrease."

[Q]: Background Paragraph: Cholesterol can't dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. Low-density lipoprotein, or LDL, is known as "bad" cholesterol. High-density lipoprotein (HDL) is known as good cholesterol. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, and lead to atherosclerosis. If a clot forms and blocks a narrowed artery, a heart attack or stroke can result. Cholesterol comes from the food you eat as well as being made by the body. To lower bad cholesterol, a diet low in saturated fat and dietary cholesterol should be followed. Regular aerobic exercise also lowers LDL cholesterol and increases HDL cholesterol.
Story: John is a doctor with the local hospital. Earlier today, he was seeing two patients, patient A and patient B. John found out that patient A had more LDL, but patient B had more HDL. He now needs to determine correct treatment for them.
[A]: Which patient would have higher risk of atherosclerosis, patient A or patient B?

[Q]: Background Paragraph: When you go to the dentist to get a tooth pulled, you really don't want to feel any pain. The dentist injects an anesthetic into your gum and it eventually becomes numb. One theory as to why anesthetics work deals with the movement of ions across the cell membrane. The anesthetic gets into the membrane structure and causes shifts in how ions move across the membrane. If ion movement is disrupted, nerve impulses will not be transmitted and you will not sense pain at least not until the anesthetic wears off.
Story: Two men, Sam and Frodo, go into the doctor's office to have the exact same procedure done to one of their arms. They won't need to be knocked out for this, but they will be given anesthetic to help with the pain. After the nurse administers the anesthetic to both men, the ions in Sam's arm continue moving across the membrane, but the ions in Frodo's arm stop moving. The doctor then comes in to begin the procedure.
[A]: Which man's nerve impulses are being transmitted?

[Q]: Background Paragraph: Just as there are good-quality grasses for putting greens, there are good-quality grasses for the fairway and rough. The quality of grass influences the roll of the ball as well as the ability of the player to "take a divot" (effectively, the ability to hit down into the ball, hitting the ball first, then hitting the turf and removing a portion of it as the club continues its arc). Fairways on prestigious tours, like the PGA Tour, are cut low. Mowing heights influence the play of the course. For example, the grass heights at U.S. Open events are alternated from one hole to the next in order to make the course more difficult. One example of this is the infamous roughs at U.S. Opens, which are often 3 to 5 inches high, depending on how close to the fairway or green the section of grass will be. This makes it difficult for a player to recover after a bad shot.
Story: The golf course at the Aurora Country Club cuts their grass to 2 1/2 inches high. The grass at the Augusta Country Club is cut to 4 inches. Sam likes more of a challenge when playing golf but Jack likes to play on turf where the ball rolls easier.
[A]:
Is it more or less challenging to play golf at the Augusta Country Club?
