Problem: Circadian rhythm:

Early research into circadian rhythms suggested that most people preferred a day closer to 25 hours when isolated from external stimuli like daylight and timekeeping. However, this research was faulty because it failed to shield the participants from artificial light. Although subjects were shielded from time cues (like clocks) and daylight, the researchers were not aware of the phase-delaying effects of indoor electric lights.[dubious discuss] The subjects were allowed to turn on light when they were awake and to turn it off when they wanted to sleep. Electric light in the evening delayed their circadian phase.[citation needed] A more stringent study conducted in 1999 by Harvard University estimated the natural human rhythm to be closer to 24 hours, 11 minutes: much closer to the solar day but still not perfectly in sync.

When did more stringent testing determine that humans preferred a 24 hour day?

A: 1999

Problem: Animal:

The Ecdysozoa are protostomes, named after the common trait of growth by moulting or ecdysis. The largest animal phylum belongs here, the Arthropoda, including insects, spiders, crabs, and their kin. All these organisms have a body divided into repeating segments, typically with paired appendages. Two smaller phyla, the Onychophora and Tardigrada, are close relatives of the arthropods and share these traits. The ecdysozoans also include the Nematoda or roundworms, perhaps the second largest animal phylum. Roundworms are typically microscopic, and occur in nearly every environment where there is water. A number are important parasites. Smaller phyla related to them are the Nematomorpha or horsehair worms, and the Kinorhyncha, Priapulida, and Loricifera. These groups have a reduced coelom, called a pseudocoelom.

What is another name for roundworms?
---
A: Nematoda

Problem: University of Kansas:

KU football dates from 1890, and has played in the Orange Bowl three times: 1948, 1968, and 2008. They are currently coached by David Beaty, who was hired in 2014. In 2008, under the leadership of Mark Mangino, the #7 Jayhawks emerged victorious in their first BCS bowl game, the FedEx Orange Bowl, with a 2421 victory over the #3 Virginia Tech Hokies. This capstone victory marked the end of the most successful season in school history, in which the Jayhawks went 121 (.923). The team plays at Memorial Stadium, which recently underwent a $31 million renovation to add the Anderson Family Football Complex, adding a football practice facility adjacent to the stadium complete with indoor partial practice field, weight room, and new locker room.

Who did KU lose to in the 2008 Orange Bowl?
