Problem: Great Plains:

The railroads opened up the Great Plains for settlement, for now it was possible to ship wheat and other crops at low cost to the urban markets in the East, and Europe. Homestead land was free for American settlers. Railroads sold their land at cheap rates to immigrants in expectation they would generate traffic as soon as farms were established. Immigrants poured in, especially from Germany and Scandinavia. On the plains, very few single men attempted to operate a farm or ranch by themselves; they clearly understood the need for a hard-working wife, and numerous children, to handle the many chores, including child-rearing, feeding and clothing the family, managing the housework, feeding the hired hands, and, especially after the 1930s, handling paperwork and financial details. During the early years of settlement, farm women played an integral role in assuring family survival by working outdoors. After approximately one generation, women increasingly left the fields, thus redefining their roles within the family. New technology including sewing and washing machines encouraged women to turn to domestic roles. The scientific housekeeping movement, promoted across the land by the media and government extension agents, as well as county fairs which featured achievements in home cookery and canning, advice columns for women regarding farm bookkeeping, and home economics courses in the schools.

who did the railroads sell cheap lands to?

A: immigrants

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Yoga school builds on the Samkhya school theory that jñāna (knowledge) is a sufficient means to moksha. It suggests that systematic techniques/practice (personal experimentation) combined with Samkhya's approach to knowledge is the path to moksha. Yoga shares several central ideas with Advaita Vedanta, with the difference that Yoga is a form of experimental mysticism while Advaita Vedanta is a form of monistic personalism. Like Advaita Vedanta, the Yoga school of Hindu philosophy states that liberation/freedom in this life is achievable, and this occurs when an individual fully understands and realizes the equivalence of Atman (soul, self) and Brahman.
What state in life does yoga believe is achievable?
A: liberation/freedom


Context and question: The Federal Supreme Court has established that treaties are subject to constitutional review and enjoy the same hierarchical position as ordinary legislation (leis ordinárias, or "ordinary laws", in Portuguese). A more recent ruling by the Supreme Court in 2008 has altered that scheme somewhat, by stating that treaties containing human rights provisions enjoy a status above that of ordinary legislation, though they remain beneath the constitution itself. Additionally, as per the 45th amendment to the constitution, human rights treaties which are approved by Congress by means of a special procedure enjoy the same hierarchical position as a constitutional amendment. The hierarchical position of treaties in relation to domestic legislation is of relevance to the discussion on whether (and how) the latter can abrogate the former and vice versa.
What is the Portuguese term for ordinary laws?
Answer: leis ordinárias


Question: The book value of the company nearly doubled from $8.19 a share in 1999 to $15 a share in 2009. Revenues grew sixfold from 1999's $6 billion to almost $36 billion in 2009. Net profit margin rose from 4.2% in 1999 to 8.4% in 2009, with operating margins improving 31 percent and return on equity doubling to 6.7 percent in the same time span. Between 1999 and 2009, return on capital nearly tripled to 7 percent. Comcast reported first quarter 2012 profit increases of 30% due to increase in high-speed internet customers. In February 2014, Comcast generated 1.1 billion in revenue during the first quarter due to the Sochi Olympics,.
Is there an answer to this question: How much revenue (in billions) did Comcast generate due to high-speed internet customers?

Answer: unanswerable


Question: Microbiological culture is a principal tool used to diagnose infectious disease. In a microbial culture, a growth medium is provided for a specific agent. A sample taken from potentially diseased tissue or fluid is then tested for the presence of an infectious agent able to grow within that medium. Most pathogenic bacteria are easily grown on nutrient agar, a form of solid medium that supplies carbohydrates and proteins necessary for growth of a bacterium, along with copious amounts of water. A single bacterium will grow into a visible mound on the surface of the plate called a colony, which may be separated from other colonies or melded together into a "lawn". The size, color, shape and form of a colony is characteristic of the bacterial species, its specific genetic makeup (its strain), and the environment that supports its growth. Other ingredients are often added to the plate to aid in identification. Plates may contain substances that permit the growth of some bacteria and not others, or that change color in response to certain bacteria and not others. Bacteriological plates such as these are commonly used in the clinical identification of infectious bacterium. Microbial culture may also be used in the identification of viruses: the medium in this case being cells grown in culture that the virus can infect, and then alter or kill. In the case of viral identification, a region of dead cells results from viral growth, and is called a "plaque". Eukaryotic parasites may also be grown in culture as a means of identifying a particular agent.
Is there an answer to this question: What type of medium is provided for a specific agent in a microbial culture?

Answer:
growth
