Problem: Avicenna:

Ibn Sina's first appointment was that of physician to the emir, Nuh II, who owed him his recovery from a dangerous illness (997). Ibn Sina's chief reward for this service was access to the royal library of the Samanids, well-known patrons of scholarship and scholars. When the library was destroyed by fire not long after, the enemies of Ibn Sina accused him of burning it, in order for ever to conceal the sources of his knowledge. Meanwhile, he assisted his father in his financial labors, but still found time to write some of his earliest works.

Context and question: There is some controversy surrounding the effect of dietary fat on the development of cardiovascular disease. People are often advised to keep a diet where less than 30% of the energy intake derives from fat, a diet that contains less than 7% of the energy intake in the form of saturated fat, and a diet that contains less than 300 mg/day of cholesterol. Replacing saturated with mono- polyunsaturated fat is also recommended, as the consumption of polyunsaturated fat instead of saturated fat may decrease coronary heart disease. Olive oil, rapeseed oil and related products are to be used instead of saturated fat.
What is a good replacement for olive oil?
Answer: unanswerable


Question: Nevertheless, the Fujiwara were not demoted by Daigo but actually became stronger during his reign. Central control of Japan had continued to decline, and the Fujiwara, along with other great families and religious foundations, acquired ever larger shōen and greater wealth during the early tenth century. By the early Heian period, the shōen had obtained legal status, and the large religious establishments sought clear titles in perpetuity, waiver of taxes, and immunity from government inspection of the shōen they held. Those people who worked the land found it advantageous to transfer title to shōen holders in return for a share of the harvest. People and lands were increasingly beyond central control and taxation, a de facto return to conditions before the Taika Reform.
Is there an answer to this question: What type of property obtained legal status during the early Heian period?

Answer: shōen
