Virtually all faculty members at Washington University engage in academic research,[citation needed] offering opportunities for both undergraduate and graduate students across the university's seven schools. Known for its interdisciplinarity and departmental collaboration, many of Washington University's research centers and institutes are collaborative efforts between many areas on campus.[citation needed] More than 60% of undergraduates are involved in faculty research across all areas; it is an institutional priority for undergraduates to be allowed to participate in advanced research. According to the Center for Measuring University Performance, it is considered to be one of the top 10 private research universities in the nation. A dedicated Office of Undergraduate Research is located on the Danforth Campus and serves as a resource to post research opportunities, advise students in finding appropriate positions matching their interests, publish undergraduate research journals, and award research grants to make it financially possible to perform research.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The typical image of migration is of northern landbirds, such as swallows (Hirundinidae) and birds of prey, making long flights to the tropics. However, many Holarctic wildfowl and finch (Fringillidae) species winter in the North Temperate Zone, in regions with milder winters than their summer breeding grounds. For example, the pink-footed goose Anser brachyrhynchus migrates from Iceland to Britain and neighbouring countries, whilst the dark-eyed junco Junco hyemalis migrates from subarctic and arctic climates to the contiguous United States and the American goldfinch from taiga to wintering grounds extending from the American South northwestward to Western Oregon. Migratory routes and wintering grounds are traditional and learned by young during their first migration with their parents. Some ducks, such as the garganey Anas querquedula, move completely or partially into the tropics. The European pied flycatcher Ficedula hypoleuca also follows this migratory trend, breeding in Asia and Europe and wintering in Africa.
Where do the European pied flycatcher breed?
A: Asia and Europe

Question: Arsenal's home colours have been the inspiration for at least three other clubs. In 1909, Sparta Prague adopted a dark red kit like the one Arsenal wore at the time; in 1938, Hibernian adopted the design of the Arsenal shirt sleeves in their own green and white strip. In 1920, Sporting Clube de Braga's manager returned from a game at Highbury and changed his team's green kit to a duplicate of Arsenal's red with white sleeves and shorts, giving rise to the team's nickname of Os Arsenalistas. These teams still wear those designs to this day.
Is there an answer to this question: What color are Sparta Prague's sleeves?

Answer: unanswerable

The use of such contractions is as old as Chinese characters themselves, and they have frequently been found in religious or ritual use. In the Oracle Bone script, personal names, ritual items, and even phrases such as () shou you "receive blessings" are commonly contracted into single characters. A dramatic example is that in medieval manuscripts pusa "bodhisattva" (simplified: ) is sometimes written with a single character formed of a 22 grid of four (derived from the grass radical over two ). However, for the sake of consistency and standardization, the CPC seeks to limit the use of such polysyllabic characters in public writing to ensure that every character only has one syllable.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What have been constantly found in religious or ritual use?
Ah, so..
Chinese characters
