Input: Read this: The exact date of creation of the Kiev Metropolis is uncertain, as well as who was the first leader of the church. Predominantly it is considered that the first head was Michael I of Kiev, however some sources also claim Leontiy who is often placed after Michael or Anastas Chersonesos, became the first bishop of the Church of the Tithes. The first metropolitan to be confirmed by historical sources is Theopemp, who was appointed by Patriarch Alexius of Constantinople in 1038. Before 1015 there were five dioceses: Kiev, Chernihiv, Bilhorod, Volodymyr, Novgorod, and soon thereafter Yuriy-upon-Ros. The Kiev Metropolitan sent his own delegation to the Council of Bari in 1098.
Question: What year was the creation of the Kiev Metropolis?

Output: unanswerable

QUES: For African Americans, the one-drop rule was a significant factor in ethnic solidarity. African Americans generally shared a common cause in society regardless of their multiracial admixture, or social/economic stratification. Additionally, African Americans found it, near, impossible to learn about their Indigenous American heritage as many family elders withheld pertinent genealogical information. Tracing the genealogy of African Americans can be a very difficult process, especially for descendants of Indigenous Americans, because African Americans who were slaves were forbidden to learn to read and write, and a majority of Indigenous Americans neither spoke English, nor read or wrote it.

What factors did not affect racial solidarity amoung African Americans?
What is the answer?
ANS: their multiracial admixture, or social/economic stratification

QUES: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.
What is the net quality of the ground dependent of?

ANS: topography

The Daily Northwestern is the main student newspaper. Established in 1881, and published on weekdays during the academic year, it is directed entirely by undergraduates. Although it serves the Northwestern community, the Daily has no business ties to the university, being supported wholly by advertisers. It is owned by the Students Publishing Company. North by Northwestern is an online undergraduate magazine, having been established in September 2006 by students at the Medill School of Journalism. Published on weekdays, it consists of updates on news stories and special events inserted throughout the day and on weekends. North by Northwestern also publishes a quarterly print magazine. Syllabus is the undergraduate yearbook. First published in 1885, the yearbook is an epitome of that year's events at Northwestern. Published by Students Publishing Company and edited by Northwestern students, it is distributed in late May. Northwestern Flipside is an undergraduate satirical magazine. Founded in 2009, The Flipside publishes a weekly issue both in print and online. Helicon is the university's undergraduate literary magazine. Started in 1979, it is published twice a year, a web issue in the Winter, and a print issue with a web complement in the Spring. The Protest is Northwestern's quarterly social justice magazine. The Northwestern division of Student Multicultural Affairs also supports publications such as NUAsian, a magazine and blog about Asian and Asian-American culture and the issues facing Asians and Asian-Americans, Ahora, a magazine about Hispanic and Latino/a culture and campus life, BlackBoard Magazine about African-American life, and Al Bayan published by the Northwestern Muslim-cultural Student Association.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who is The Daily Northwestern entirely directed by?
Ah, so.. undergraduates

Question: Earth was initially molten due to extreme volcanism and frequent collisions with other bodies. Eventually, the outer layer of the planet cooled to form a solid crust when water began accumulating in the atmosphere. The Moon formed soon afterwards, possibly as the result of a Mars-sized object with about 10% of the Earth's mass impacting the planet in a glancing blow. Some of this object's mass merged with the Earth, significantly altering its internal composition, and a portion was ejected into space. Some of the material survived to form an orbiting moon. Outgassing and volcanic activity produced the primordial atmosphere. Condensing water vapor, augmented by ice delivered from comets, produced the oceans.
Try to answer this question if possible: What formed as water accumulated?
Answer: unanswerable

Question: Many long-distance migrants appear to be genetically programmed to respond to changing day length. Species that move short distances, however, may not need such a timing mechanism, instead moving in response to local weather conditions. Thus mountain and moorland breeders, such as wallcreeper Tichodroma muraria and white-throated dipper Cinclus cinclus, may move only altitudinally to escape the cold higher ground. Other species such as merlin Falco columbarius and Eurasian skylark Alauda arvensis move further, to the coast or towards the south. Species like the chaffinch are much less migratory in Britain than those of continental Europe, mostly not moving more than 5 km in their lives.
Try to answer this question if possible: Where do the merlin Falco columbarius migrate to?
Answer:
the coast or towards the south
