Input: Infection
Because it is normal to have bacterial colonization, it is difficult to know which chronic wounds are infected. Despite the huge number of wounds seen in clinical practice, there are limited quality data for evaluated symptoms and signs. A review of chronic wounds in the Journal of the American Medical Association's "Rational Clinical Examination Series" quantified the importance of increased pain as an indicator of infection. The review showed that the most useful finding is an increase in the level of pain [likelihood ratio (LR) range, 11-20] makes infection much more likely, but the absence of pain (negative likelihood ratio range, 0.64-0.88) does not rule out infection (summary LR 0.64-0.88).

What is increased pain an indicator of?
Output: infection

Input: Richmond, Virginia
Auto racing is also popular in the area. The Richmond International Raceway (RIR) has hosted NASCAR Sprint Cup races since 1953, as well as the Capital City 400 from 1962 1980. RIR also hosted IndyCar's Suntrust Indy Challenge from 2001 2009. Another track, Southside Speedway, has operated since 1959 and sits just southwest of Richmond in Chesterfield County. This .333-mile (0.536 km) oval short-track has become known as the "Toughest Track in the South" and "The Action Track", and features weekly stock car racing on Friday nights. Southside Speedway has acted as the breeding grounds for many past NASCAR legends including Richard Petty, Bobby Allison and Darrell Waltrip, and claims to be the home track of NASCAR superstar Denny Hamlin.

When did the RIR begin to host the Capital City 400?
Output: 1962

Input: Multiracial American
Population testing is still being done. Some Native American groups that have been sampled may not have shared the pattern of markers being searched for. Geneticists acknowledge that DNA testing cannot yet distinguish among members of differing cultural Native American nations. There is genetic evidence for three major migrations into North America, but not for more recent historic differentiation. In addition, not all Native Americans have been tested, so scientists do not know for sure that Native Americans have only the genetic markers they have identified.

Who says genetic tests can't tell the difference between different Native American nations?
Output: Geneticists

Input: Buddhism
Pre-sectarian Buddhism is the earliest phase of Buddhism, recognized by nearly all scholars. Its main scriptures are the Vinaya Pitaka and the four principal Nikayas or Agamas. Certain basic teachings appear in many places throughout the early texts, so most scholars conclude that Gautama Buddha must have taught something similar to the Three marks of existence, the Five Aggregates, dependent origination, karma and rebirth, the Four Noble Truths, the Noble Eightfold Path, and nirvana. Some scholars disagree, and have proposed many other theories.

Gautama buddha taught what Path concept?
Output:
Noble Eightfold
