Question: Background Paragraph: An apex predator, also known as an alpha predator or top predator, is a predator at the top of a food chain, with no natural predators.Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels. Food chains are often far shorter on land, usually limited to being secondary consumers – for example, wolves prey mostly upon large herbivores (primary consumers), which eat plants (primary producers). The apex predator concept is applied in wildlife management, conservation and ecotourism. 
Story: Two cousins were fascinated about food chains in nature. Liam started reading about apex predators, while Fox read about grazers and large herbivores. 
Question: Which cousin learned less about primary consumers?

Answer: Liam.


Question: Background Paragraph: The body's second line of defense against pathogens includes the inflammatory response. If bacteria enter the skin through a scrape, the area may become red, warm, and painful. These are signs of inflammation. Inflammation is one way the body reacts to infections or injuries. Inflammation is caused by chemicals that are released when skin or other tissues are damaged. The chemicals cause nearby blood vessels to dilate, or expand. This increases blood flow to the damaged area, which makes the area red and slightly warm. The chemicals also attract white blood cells called neutrophils to the wound and cause them to leak out of blood vessels into the damaged tissue. 
Story: John and Keith were playing football - the game was rough to say the least. They both got hurt. After the game they went to see the sports physician for a check up. The physician found that John had inflammation, but Keith didn't have any inflammation. 
Question: Who would most likely be in pain, John or Keith?

Answer: John.


Question: Background Paragraph: Existing data on the role of immigration on residential segregation trends in the US suggest that foreign-born Hispanics, Asians and blacks often have higher rates of segregation than do native-born individuals from these groups. Segregation of immigrants is associated with their low-income status, language barriers, and support networks in these enclaves. Research on assimilation shows that while new immigrants settle in homogenous ethnic communities, segregation of immigrants declines as they gain socioeconomic status and move away from these communities, integrating with the native-born. 
Story: A recent study has been published about two U.S cities containing large Hispanic population and their origins. Los Angeles which has a larger native born population, and San Diego, which is formed mostly of immigrants that have been foreign-born, have been listed as the top two. 
Question: Will Los Angeles or San Diego more likely have higher rates of segregation in it's population?

Answer:
San Diego.
