Problem: Born in Bay City, Michigan, Madonna moved to New York City in 1977 to pursue a career in modern dance. After performing in the music groups Breakfast Club and Emmy, she signed with Sire Records (an auxiliary label of Warner Bros. Records) in 1982 and released her self-titled debut album the following year. She followed it with a series of commercially and critcally successful albums, including the Grammy Award winners Ray of Light (1998) and Confessions on a Dance Floor (2005). Throughout her career, Madonna has written and produced most of her songs, with many of them reaching number one on the record charts, including "Like a Virgin", "Into the Groove", "Papa Don't Preach", "Like a Prayer", "Vogue", "Frozen", "Music", "Hung Up", and "4 Minutes".

Problem: Family history is a risk factor for asthma, with many different genes being implicated. If one identical twin is affected, the probability of the other having the disease is approximately 25%. By the end of 2005, 25 genes had been associated with asthma in six or more separate populations, including GSTM1, IL10, CTLA-4, SPINK5, LTC4S, IL4R and ADAM33, among others. Many of these genes are related to the immune system or modulating inflammation. Even among this list of genes supported by highly replicated studies, results have not been consistent among all populations tested. In 2006 over 100 genes were associated with asthma in one genetic association study alone; more continue to be found.
In 2006 what percentage of genes were found to contribute to inflammation?

Answer: unanswerable

Problem: Underpinning Houston's land surface are unconsolidated clays, clay shales, and poorly cemented sands up to several miles deep. The region's geology developed from river deposits formed from the erosion of the Rocky Mountains. These sediments consist of a series of sands and clays deposited on decaying organic marine matter, that over time, transformed into oil and natural gas. Beneath the layers of sediment is a water-deposited layer of halite, a rock salt. The porous layers were compressed over time and forced upward. As it pushed upward, the salt dragged surrounding sediments into salt dome formations, often trapping oil and gas that seeped from the surrounding porous sands. The thick, rich, sometimes black, surface soil is suitable for rice farming in suburban outskirts where the city continues to grow.
What type of farming is Houston's surface soil good for?
---
Answer:
rice farming
