Problem: Montana:

Montana schoolchildren played a significant role in selecting several state symbols. The state tree, the ponderosa pine, was selected by Montana schoolchildren as the preferred state tree by an overwhelming majority in a referendum held in 1908. However, the legislature did not designate a state tree until 1949, when the Montana Federation of Garden Clubs, with the support of the state forester, lobbied for formal recognition. Schoolchildren also chose the western meadowlark as the state bird, in a 1930 vote, and the legislature acted to endorse this decision in 1931. Similarly, the secretary of state sponsored a children's vote in 1981 to choose a state animal, and after 74 animals were nominated, the grizzly bear won over the elk by a 21 margin. The students of Livingston started a statewide school petition drive plus lobbied the governor and the state legislature to name the Maiasaura as the state fossil in 1985.

What is the state animal of Montana?

A: grizzly bear

Problem: In Iran (Persia), the history of cotton dates back to the Achaemenid era (5th century BC); however, there are few sources about the planting of cotton in pre-Islamic Iran. The planting of cotton was common in Merv, Ray and Pars of Iran. In Persian poets' poems, especially Ferdowsi's Shahname, there are references to cotton ("panbe" in Persian). Marco Polo (13th century) refers to the major products of Persia, including cotton. John Chardin, a French traveler of the 17th century who visited the Safavid Persia, spoke approvingly of the vast cotton farms of Persia.
In what source can references to cotton be found in Iran?
---
Answer: Persian poets' poems

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The Arians no longer presented an unbroken front to their orthodox opponents. The Emperor Constantius, who had been the cause of so much trouble, died 4 November, 361 and was succeeded by Julian. The proclamation of the new prince's accession was the signal for a pagan outbreak against the still dominant Arian faction in Alexandria. George, the usurping Bishop, was flung into prison and murdered. An obscure presbyter of the name of Pistus was immediately chosen by the Arians to succeed him, when fresh news arrived that filled the orthodox party with hope. An edict had been put forth by Julian permitting the exiled bishops of the "Galileans" to return to their "towns and provinces". Athanasius received a summons from his own flock, and he accordingly re-entered his episcopal capitol on 22 February, 362.
Who preceded Emperor Constantius?
A: unanswerable

Context and question: In Australia, a technical issue arose with the royal assent in both 1976 and 2001. In 1976, a bill originating in the House of Representatives was mistakenly submitted to the Governor-General and assented to. However, it was later discovered that it had not been passed by each house. The error arose because two bills of the same title had originated from the house. The Governor-General revoked the first assent, before assenting to the bill which had actually passed. The same procedure was followed to correct a similar error which arose in 2001.
What was the reason a bill was accidentally assented in 1976?
Answer: two bills of the same title had originated from the house

Question: Jan Joosten van Lodensteijn (1556?1623?), a Dutch colleague of Adams' on their ill-fated voyage to Japan in the ship De Liefde, was also given similar privileges by Tokugawa Ieyasu. It appears Joosten became a samurai[citation needed] and was given a residence within Ieyasu's castle at Edo. Today, this area at the east exit of Tokyo Station is known as Yaesu (). Yaesu is a corruption of the Dutchman's Japanese name, Yayousu (). Also in common with Adam's, Joostens was given a Red Seal Ship () allowing him to trade between Japan and Indo-China. On a return journey from Batavia Joosten drowned after his ship ran aground.
Is there an answer to this question: What was Jan Joosten van Lodensteijn's Japanese name?

Answer: Yayousu

Problem: Valencia:

Ferdinand refused and went to Valencia instead of Madrid. Here, on 17 April, General Elio invited the King to reclaim his absolute rights and put his troops at the King's disposition. The king abolished the Constitution of 1812. He followed this act by dissolving the two chambers of the Spanish Parliament on 10 May. Thus began six years (18141820) of absolutist rule, but the constitution was reinstated during the Trienio Liberal, a period of three years of liberal government in Spain from 18201823.

Who offered troops to the King?
---
A:
General Elio
