Input: Article: All modern birds lie within the crown group Aves (alternately Neornithes), which has two subdivisions: the Palaeognathae, which includes the flightless ratites (such as the ostriches) and the weak-flying tinamous, and the extremely diverse Neognathae, containing all other birds. These two subdivisions are often given the rank of superorder, although Livezey and Zusi assigned them "cohort" rank. Depending on the taxonomic viewpoint, the number of known living bird species varies anywhere from 9,800 to 10,050.

Now answer this question: All modern birds lie within which crown group?

Output: Aves

Input: Article: The health benefits of dogs can result from contact with dogs in general, and not solely from having dogs as pets. For example, when in the presence of a pet dog, people show reductions in cardiovascular, behavioral, and psychological indicators of anxiety. Other health benefits are gained from exposure to immune-stimulating microorganisms, which, according to the hygiene hypothesis, can protect against allergies and autoimmune diseases. The benefits of contact with a dog also include social support, as dogs are able to not only provide companionship and social support themselves, but also to act as facilitators of social interactions between humans. One study indicated that wheelchair users experience more positive social interactions with strangers when they are accompanied by a dog than when they are not. In 2015, a study found that pet owners were significantly more likely to get to know people in their neighborhood than non-pet owners.

Now answer this question: What is lessened when people are with their pet dogs?

Output: anxiety

Input: Article: According to the U.S. Census Bureau, as of 2015, Tennessee had an estimated population of 6,600,299, which is an increase of 50,947, from the prior year and an increase of 254,194, or 4.01%, since the year 2010. This includes a natural increase since the last census of 142,266 people (that is 493,881 births minus 351,615 deaths), and an increase from net migration of 219,551 people into the state. Immigration from outside the United States resulted in a net increase of 59,385 people, and migration within the country produced a net increase of 160,166 people. Twenty percent of Tennesseans were born outside the South in 2008, compared to a figure of 13.5% in 1990.

Now answer this question: How much of Tennessee's population increase between 2010 and 2015 was due to migration?

Output:
219,551
