Problem: Mosaic:

There are very few existing mosaics from the Komnenian period but this paucity must be due to accidents of survival and gives a misleading impression. The only surviving 12th-century mosaic work in Constantinople is a panel in Hagia Sophia depicting Emperor John II and Empress Eirene with the Theotokos (112234). The empress with her long braided hair and rosy cheeks is especially capturing. It must be a lifelike portrayal because Eirene was really a redhead as her original Hungarian name, Piroska shows. The adjacent portrait of Emperor Alexios I Komnenos on a pier (from 1122) is similarly personal. The imperial mausoleum of the Komnenos dynasty, the Pantokrator Monastery was certainly decorated with great mosaics but these were later destroyed. The lack of Komnenian mosaics outside the capital is even more apparent. There is only a "Communion of the Apostles" in the apse of the cathedral of Serres.

The empress Eirene had what color hair?

A: red

Problem: Since 1962, the cardinal bishops have only a titular relationship with the suburbicarian sees, with no powers of governance over them. Each see has its own bishop, with the exception of Ostia, in which the Cardinal Vicar of the see of Rome is apostolic administrator.
Who had powers of governance over suburbicarian sees?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In 1971, Akira Endo, a Japanese biochemist working for the pharmaceutical company Sankyo, identified mevastatin (ML-236B), a molecule produced by the fungus Penicillium citrinum, as an inhibitor of HMG-CoA reductase, a critical enzyme used by the body to produce cholesterol. Animal trials showed very good inhibitory effect as in clinical trials, however a long term study in dogs found toxic effects at higher doses and as a result mevastatin was believed to be too toxic for human use. Mevastatin was never marketed, because of its adverse effects of tumors, muscle deterioration, and sometimes death in laboratory dogs.
What is Penicillium responsible for producing?
A: unanswerable

Context and question: Construction of the chapel, originally intended to be slightly over twice as long, with eighteen - or possibly seventeen - bays (there are eight today) was stopped when Henry VI was deposed. Only the Quire of the intended building was completed. Eton's first Headmaster, William Waynflete, founder of Magdalen College, Oxford and previously Head Master of Winchester College, built the ante-chapel that finishes the Chapel today. The important wall paintings in the Chapel and the brick north range of the present School Yard also date from the 1480s; the lower storeys of the cloister, including College Hall, had been built between 1441 and 1460.
In what year did William Waynflete die?
Answer: unanswerable

Question: Greenwich Mean Time (GMT) is an older standard, adopted starting with British railways in 1847. Using telescopes instead of atomic clocks, GMT was calibrated to the mean solar time at the Royal Observatory, Greenwich in the UK. Universal Time (UT) is the modern term for the international telescope-based system, adopted to replace "Greenwich Mean Time" in 1928 by the International Astronomical Union. Observations at the Greenwich Observatory itself ceased in 1954, though the location is still used as the basis for the coordinate system. Because the rotational period of Earth is not perfectly constant, the duration of a second would vary if calibrated to a telescope-based standard like GMT or UTin which a second was defined as a fraction of a day or year. The terms "GMT" and "Greenwich Mean Time" are sometimes used informally to refer to UT or UTC.
Is there an answer to this question: The term calibrated is also used informally to refer to what?

Answer: unanswerable

QUES: Avicenna's psychology requires that connection between the body and soul be strong enough to ensure the soul's individuation, but weak enough to allow for its immortality. Avicenna grounds his psychology on physiology, which means his account of the soul is one that deals almost entirely with the natural science of the body and its abilities of perception. Thus, the philosopher's connection between the soul and body is explained almost entirely by his understanding of perception; in this way, bodily perception interrelates with the immaterial human intellect. In sense perception, the perceiver senses the form of the object; first, by perceiving features of the object by our external senses. This sensory information is supplied to the internal senses, which merge all the pieces into a whole, unified conscious experience. This process of perception and abstraction is the nexus of the soul and body, for the material body may only perceive material objects, while the immaterial soul may only receive the immaterial, universal forms. The way the soul and body interact in the final abstraction of the universal from the concrete particular is the key to their relationship and interaction, which takes place in the physical body.

How does man first perceive features of an object?
What is the answer?
ANS:
external senses
