Article: Fryderyk's father, Nicolas Chopin, was a Frenchman from Lorraine who had emigrated to Poland in 1787 at the age of sixteen. Nicolas tutored children of the Polish aristocracy, and in 1806 married Justyna Krzyżanowska, a poor relative of the Skarbeks, one of the families for whom he worked. Fryderyk was baptized on Easter Sunday, 23 April 1810, in the same church where his parents had married, in Brochów. His eighteen-year-old godfather, for whom he was named, was Fryderyk Skarbek, a pupil of Nicolas Chopin. Fryderyk was the couple's second child and only son; he had an elder sister, Ludwika (1807–55), and two younger sisters, Izabela (1811–81) and Emilia (1812–27). Nicolas was devoted to his adopted homeland, and insisted on the use of the Polish language in the household.

Question: Who did Frédéric's father marry in 1806?
Ans: Justyna Krzyżanowska


Article: The Alps are a crescent shaped geographic feature of central Europe that ranges in a 800 km (500 mi) arc from east to west and is 200 km (120 mi) in width. The mean height of the mountain peaks is 2.5 km (1.6 mi). The range stretches from the Mediterranean Sea north above the Po basin, extending through France from Grenoble, eastward through mid and southern Switzerland. The range continues toward Vienna in Austria, and east to the Adriatic Sea and into Slovenia. To the south it dips into northern Italy and to the north extends to the south border of Bavaria in Germany. In areas like Chiasso, Switzerland, and Neuschwanstein, Bavaria, the demarcation between the mountain range and the flatlands are clear; in other places such as Geneva, the demarcation is less clear. The countries with the greatest alpine territory are Switzerland, France, Austria and Italy.

Question: What is the mean height of the Alp's peak?
Ans: 2.5 km (1.6 mi)


Article: 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.

Question: What else are these genes closely related to?
Ans: the immune system or modulating inflammation


Article: Generally, scholars conclude that the Mahayana scriptures were composed from the 1st century CE onwards: "Large numbers of Mahayana sutras were being composed in the period between the beginning of the common era and the fifth century", five centuries after the historical Gautama Buddha. Some of these had their roots in other scriptures composed in the 1st century BCE. It was not until after the 5th century CE that the Mahayana sutras started to influence the behavior of mainstream Buddhists in India: "But outside of texts, at least in India, at exactly the same period, very different—in fact seemingly older—ideas and aspirations appear to be motivating actual behavior, and old and established Hinnayana groups appear to be the only ones that are patronized and supported." These texts were apparently not universally accepted among Indian Buddhists when they appeared; the pejorative label Hinayana was applied by Mahayana supporters to those who rejected the Mahayana sutras.

Question: When did Mahayana sutras start to influence the behavior of mainstream buddhists in India?
Ans:
after the 5th century CE
