TASK DEFINITION: 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."
PROBLEM: Background Paragraph: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition.
Story: Doctors studied two groups of patients. Group W which had people with sickle cell disease, and group A which had normal people in it.

SOLUTION: Which group had fewer individuals inheriting the gene from both parents ?

PROBLEM: Background Paragraph: Since AM fungi are biotrophic, they are dependent on plants for the growth of their hyphal networks. Growing a cover crop extends the time for AM growth into the autumn, winter, and spring. Promotion of hyphal growth creates a more extensive hyphal network. The mycorrhizal colonization increase found in cover crops systems may be largely attributed to an increase in the extraradical hyphal network that can colonize the roots of the new crop (Boswell et al. 1998). The extraradical mycelia are able to survive the winter, providing rapid spring colonization and early season symbiosis (McGonigle and Miller 1999). This early symbiosis allows plants to tap into the well-established hyphal network and be supplied with adequate phosphorus nutrition during early growth, which greatly improves the crop yield.
Story: Two farms used AM fungi for the plants. Brown farm also decided to grow cover crops on those parcels of land to help mycorrhizal growth. Orange farm didn't grow cover crops.

SOLUTION: Which farm didn't increase the extraradical hyphal network that can colonize the roots of the new crop?

PROBLEM: Background Paragraph: New species develop naturally through the process of natural selection . Due to natural selection, organisms with traits that better enable them to adapt to their environment will tend to survive and reproduce in greater numbers. Natural selection causes beneficial heritable traits to become more common in a population and unfavorable heritable traits to become less common. For example, a giraffe's neck is beneficial because it allows the giraffe to reach leaves high in trees. Natural selection caused this beneficial trait to become more common than short necks.
Story: A large group of bears lives in a forest. Over time the climate of the forest changes and becomes very cold. Some of the bears have thicker fur while some of the others have thinner fur. Due to the cold weather the bears with thinner fur die earlier. Also the bears with thicker fur have an easier time finding mates. Because of this the bears with thick fur have their traits passed on more often and bears with thin fur appear less and less in the population.

SOLUTION:
Given a sudden shift in the climate of the forest, becoming hotter, will bears with thick fur or thin fur be more successful?
