Problem: Symbiosis:

Symbiotic relationships include those associations in which one organism lives on another (ectosymbiosis, such as mistletoe), or where one partner lives inside the other (endosymbiosis, such as lactobacilli and other bacteria in humans or Symbiodinium in corals). Symbiosis is also classified by physical attachment of the organisms; symbiosis in which the organisms have bodily union is called conjunctive symbiosis, and symbiosis in which they are not in union is called disjunctive symbiosis.

What is an example of ectosymbiosis?

A: mistletoe

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The traditional parish system persisted until the Reconstruction Era, when counties were imposed.[citation needed] Nevertheless, traditional parishes still exist in various capacities, mainly as public service districts. When the city of Charleston was formed, it was defined by the limits of the Parish of St. Philip and St. Michael, now also includes parts of St. James' Parish, St. George's Parish, St. Andrew's Parish, and St. John's Parish, although the last two are mostly still incorporated rural parishes.
The city of Charleston isn't defined by the limits of the Parish of St. Michael and what other parish?
A: unanswerable

Context and question: Although the doctrine of Mary's Immaculate Conception appears only later among Latin (and particularly Frankish) theologians, it became ever more manifest among Byzantine theologians reliant on Gregory Nazianzen's Mariology in the Medieval or Byzantine East. Although hymnographers and scholars, like the Emperor Justinian I, were accustomed to call Mary "prepurified" in their poetic and credal statements, the first point of departure for more fully commenting on Nazianzen's meaning occurs in Sophronius of Jerusalem. In other places Sophronius explains that the Theotokos was already immaculate, when she was "purified" at the Annunciation and goes so far as to note that John the Baptist is literally "holier than all 'Men' born of woman" since Mary's surpassing holiness signifies that she was holier than even John after his sanctification in utero. Sophronius' teaching is augmented and incorporated by St. John Damascene (d. 749/750). John, besides many passages wherein he extolls the Theotokos for her purification at the Annunciation, grants her the unique honor of "purifying the waters of baptism by touching them." This honor was most famously and firstly attributed to Christ, especially in the legacy of Nazianzen. As such, Nazianzen's assertion of parallel holiness between the prepurified Mary and purified Jesus of the New Testament is made even more explicit in Damascene in his discourse on Mary's holiness to also imitate Christ's baptism at the Jordan. The Damascene's hymnongraphy and De fide Orthodoxa explicitly use Mary's "pre purification" as a key to understanding her absolute holiness and unsullied human nature. In fact, Damascene (along with Nazianzen) serves as the source for nearly all subsequent promotion of Mary's complete holiness from her Conception by the "all pure seed" of Joachim and the womb "wider than heaven" of St. Ann.
What event happened to Theotokos that was of significant religious note ?
Answer: she was "purified" at the Annunciation

Question: During the Tokugawa shogunate, samurai increasingly became courtiers, bureaucrats, and administrators rather than warriors. With no warfare since the early 17th century, samurai gradually lost their military function during the Tokugawa era (also called the Edo period). By the end of the Tokugawa era, samurai were aristocratic bureaucrats for the daimyo, with their daisho, the paired long and short swords of the samurai (cf. katana and wakizashi) becoming more of a symbolic emblem of power rather than a weapon used in daily life. They still had the legal right to cut down any commoner who did not show proper respect kiri-sute gomen (?), but to what extent this right was used is unknown. When the central government forced daimyos to cut the size of their armies, unemployed ronin became a social problem.
Is there an answer to this question: What was another name for the Tokugawa era?

Answer: the Edo period
