Problem: Modern history:

Society in the Japanese "Tokugawa period" (Edo society), unlike the shogunates before it, was based on the strict class hierarchy originally established by Toyotomi Hideyoshi. The daimyo, or lords, were at the top, followed by the warrior-caste of samurai, with the farmers, artisans, and traders ranking below. In some parts of the country, particularly smaller regions, daimyo and samurai were more or less identical, since daimyo might be trained as samurai, and samurai might act as local lords. Otherwise, the largely inflexible nature of this social stratification system unleashed disruptive forces over time. Taxes on the peasantry were set at fixed amounts which did not account for inflation or other changes in monetary value. As a result, the tax revenues collected by the samurai landowners were worth less and less over time. This often led to numerous confrontations between noble but impoverished samurai and well-to-do peasants, ranging from simple local disturbances to much bigger rebellions. None, however, proved compelling enough to seriously challenge the established order until the arrival of foreign powers.

Strict class hierarchy was established by who?

A: Toyotomi Hideyoshi

The United States provides Egypt with annual military assistance, which in 2015 amounted to US$1.3 billion. In 1989, Egypt was designated as a major non-NATO ally of the United States. Nevertheless, ties between the two countries have partially soured since the July 2013 military coup that deposed Islamist president Mohamed Morsi, with the Obama administration condemning Egypt's violent crackdown on the Muslim Brotherhood and its supporters, and cancelling future military exercises involving the two countries. There have been recent attempts, however, to normalise relations between the two, with both governments frequently calling for mutual support in the fight against regional and international terrorism.
What event soured relations of US and Egypt in 2013?
A: Egypt's violent crackdown on the Muslim Brotherhood and its supporters

Context and question: After the Voyager 2 flyby mission, the next step in scientific exploration of the Neptunian system, is considered to be a Flagship orbital mission. Such a hypothetical mission is envisioned to be possible at in the late 2020s or early 2030s. However, there have been a couple of discussions to launch Neptune missions sooner. In 2003, there was a proposal in NASA's "Vision Missions Studies" for a "Neptune Orbiter with Probes" mission that does Cassini-level science. Another, more recent proposal was for Argo, a flyby spacecraft to be launched in 2019, that would visit Jupiter, Saturn, Neptune, and a Kuiper belt object. The focus would be on Neptune and its largest moon Triton to be investigated around 2029. The proposed New Horizons 2 mission (which was later scrapped) might also have done a close flyby of the Neptunian system.
When can we expect Argo to visit Mars?
Answer: unanswerable

Question: Of Alaska's 2010 Census population figure of 710,231, 20,429 people, or 2.88% of the population, did not live in an incorporated city or census-designated place. Approximately three-quarters of that figure were people who live in urban and suburban neighborhoods on the outskirts of the city limits of Ketchikan, Kodiak, Palmer and Wasilla. CDPs have not been established for these areas by the United States Census Bureau, except that seven CDPs were established for the Ketchikan-area neighborhoods in the 1980 Census (Clover Pass, Herring Cove, Ketchikan East, Mountain Point, North Tongass Highway, Pennock Island and Saxman East), but have not been used since. The remaining population was scattered throughout Alaska, both within organized boroughs and in the Unorganized Borough, in largely remote areas.
Is there an answer to this question: What five areas have not been established as CDPs by the Census Bureau?

Answer: unanswerable

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 shoen and greater wealth during the early tenth century. By the early Heian period, the shoen had obtained legal status, and the large religious establishments sought clear titles in perpetuity, waiver of taxes, and immunity from government inspection of the shoen they held. Those people who worked the land found it advantageous to transfer title to shoen 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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Who was demoted during the reign of Deigo?
Ah, so..
unanswerable
