input question: Extract the answer to the question from the following context. Question: How does the primary motor cortex allow us to fine tune our movements? Context: The brain contains several motor areas that project directly to the spinal cord. At the lowest level are motor areas in the medulla and pons, which control stereotyped movements such as walking, breathing, or swallowing. At a higher level are areas in the midbrain, such as the red nucleus, which is responsible for coordinating movements of the arms and legs. At a higher level yet is the primary motor cortex, a strip of tissue located at the posterior edge of the frontal lobe. The primary motor cortex sends projections to the subcortical motor areas, but also sends a massive projection directly to the spinal cord, through the pyramidal tract. This direct corticospinal projection allows for precise voluntary control of the fine details of movements. Other motor-related brain areas exert secondary effects by projecting to the primary motor areas. Among the most important secondary areas are the premotor cortex, basal ganglia, and cerebellum.???
output answer: sends projections to the subcortical motor areas, but also sends a massive projection directly to the spinal cord

Extract the answer to the question from the following context. Question: Which of the following is the HR department responsible for: maintaining the database, calculating expenses, or tracking employee details? Context: While there is typically only one conceptual (or logical) and physical (or internal) view of the data, there can be any number of different external views. This allows users to see database information in a more business-related way rather than from a technical, processing viewpoint. For example, a financial department of a company needs the payment details of all employees as part of the company's expenses, but does not need details about employees that are the interest of the human resources department. Thus different departments need different views of the company's database.
----
Answer: details about employees

Q: Extract the answer to the question from the following context. Question: What connects the modern reptiles to their ancestors? Context: The early synapsid mammalian ancestors were sphenacodont pelycosaurs, a group that produced the non-mammalian Dimetrodon. At the end of the Carboniferous period, this group diverged from the sauropsid line that led to today's reptiles and birds. The line following the stem group Sphenacodontia split-off several diverse groups of non-mammalian synapsids—sometimes referred to as mammal-like reptiles—before giving rise to the proto-mammals (Therapsida) in the early Mesozoic era. The modern mammalian orders arose in the Paleogene and Neogene periods of the Cenozoic era, after the extinction of the non-avian dinosaurs 66 million years ago.
A: pelycosaurs

Question: Extract the answer to the question from the following context. Question: Pennies and nickels are what kind of currency? Context: New York is the most important source of political fundraising in the United States, as four of the top five ZIP codes in the nation for political contributions are in Manhattan. The top ZIP code, 10021 on the Upper East Side, generated the most money for the 2004 presidential campaigns of George W. Bush and John Kerry. The city has a strong imbalance of payments with the national and state governments. It receives 83 cents in services for every $1 it sends to the federal government in taxes (or annually sends $11.4 billion more than it receives back). The city also sends an additional $11 billion more each year to the state of New York than it receives back.
Answer: cents

[Q]: Extract the answer to the question from the following context. Question: Suggesting that young people work is often seen as what? Context: Some scholars[who?] suggest any labour by children aged 18 years or less is wrong since this encourages illiteracy, inhumane work and lower investment in human capital. Child labour, claim these activists, also leads to poor labour standards for adults, depresses the wages of adults in developing countries as well as the developed countries, and dooms the third world economies to low-skill jobs only capable of producing poor quality cheap exports. More children that work in poor countries, the fewer and worse-paid are the jobs for adults in these countries. In other words, there are moral and economic reasons that justify a blanket ban on labour from children aged 18 years or less, everywhere in the world.

[A]: encourages illiteracy, inhumane work and lower investment in human capital

Problem: Given the question: Extract the answer to the question from the following context. Question: What was sold in 3 years? Context: While the original Xbox sold poorly in Japan, selling just 2 million units while it was on the market (between 2002 and 2005),[citation needed] the Xbox 360 sold even more poorly, selling only 1.5 million units from 2005 to 2011. Edge magazine reported in August 2011 that initially lackluster and subsequently falling sales in Japan, where Microsoft had been unable to make serious inroads into the dominance of domestic rivals Sony and Nintendo, had led to retailers scaling down and in some cases discontinuing sales of the Xbox 360 completely.

The answer is:

2 million units
