Question: 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.
Try to answer this question if possible: How many genes were associated with asthma in 2006?
Answer: over 100 genes
Question: All of the highways into Wenchuan, and others throughout the province, were damaged, resulting in delayed arrival of the rescue troops. In Beichuan County, 80% of the buildings collapsed according to Xinhua News. In the city of Shifang, the collapse of two chemical plants led to leakage of some 80 tons of liquid ammonia, with hundreds of people reported buried. In the city of Dujiangyan, south-east of the epicenter, a whole school collapsed with 900 students buried and fewer than 60 survived. The Juyuan Middle School, where many teenagers were buried, was excavated by civilians and cranes. Dujiangyan is home of the Dujiangyan Irrigation System, an ancient water diversion project which is still in use and is a UNESCO World Heritage Site. The project's famous Fish Mouth was cracked but not severely damaged otherwise.
Try to answer this question if possible: What did the damaged roadways cause to the rescue operations?
Answer: delayed arrival
Question: In quantum mechanics, energy is defined in terms of the energy operator as a time derivative of the wave function. The Schrodinger equation equates the energy operator to the full energy of a particle or a system. Its results can be considered as a definition of measurement of energy in quantum mechanics. The Schrodinger equation describes the space- and time-dependence of a slowly changing (non-relativistic) wave function of quantum systems. The solution of this equation for a bound system is discrete (a set of permitted states, each characterized by an energy level) which results in the concept of quanta. In the solution of the Schrodinger equation for any oscillator (vibrator) and for electromagnetic waves in a vacuum, the resulting energy states are related to the frequency by Planck's relation: (where is Planck's constant and the frequency). In the case of an electromagnetic wave these energy states are called quanta of light or photons.

Answer: unanswerable
Question: The Great Plains is the broad expanse of flat land (a plain), much of it covered in prairie, steppe and grassland, that lies west of the Mississippi River tallgrass prairie states and east of the Rocky Mountains in the United States and Canada. This area covers parts, but not all, of the states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The region is known for supporting extensive cattle ranching and dry farming.
Try to answer this question if possible: What lies north of the Great Plains?
Answer:
unanswerable
