Problem: In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.
Who signed the Union of Utrecht in the 15th century?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
A number of theories have been proposed regarding Avicenna's madhab (school of thought within Islamic jurisprudence). Medieval historian Zahir al-din al-Bayhaqi (d. 1169) considered Avicenna to be a follower of the Brethren of Purity. On the other hand, Dimitri Gutas along with Aisha Khan and Jules J. Janssens demonstrated that Avicenna was a Sunni Hanafi. However, the 14th cenutry Shia faqih Nurullah Shushtari according to Seyyed Hossein Nasr, maintained that he was most likely a Twelver Shia. Conversely, Sharaf Khorasani, citing a rejection of an invitation of the Sunni Governor Sultan Mahmoud Ghazanavi by Avicenna to his court, believes that Avicenna was an Ismaili. Similar disagreements exist on the background of Avicenna's family, whereas some writers considered them Sunni, some more recent writers contested that they were Shia.
What type of Islamic school did Avicenna invent?
A: unanswerable

Context and question: The responsibility for military command remained with the British Crown-in-Council, with a commander-in-chief for North America stationed at Halifax until the final withdrawal of British Army and Royal Navy units from that city in 1906. Thereafter, the Royal Canadian Navy was formed, and, with the advent of military aviation, the Royal Canadian Air Force. These forces were organised under the Department of Militia and Defence, and split into the Permanent and Non-Permanent Active Militiasfrequently shortened to simply The Militia. By 1923, the department was merged into the Department of National Defence, but land forces in Canada were not referred to as the Canadian Army until November 1940.
Who initially didn't have military command?
Answer: unanswerable

Question: Support for the U.S. cooled when America made clear its determination to invade Iraq in late 2002. Even so, many of the "coalition of the willing" countries that unconditionally supported the U.S.-led military action have sent troops to Afghanistan, particular neighboring Pakistan, which has disowned its earlier support for the Taliban and contributed tens of thousands of soldiers to the conflict. Pakistan was also engaged in the War in North-West Pakistan (Waziristan War). Supported by U.S. intelligence, Pakistan was attempting to remove the Taliban insurgency and al-Qaeda element from the northern tribal areas.
Is there an answer to this question: Which country refused to send troops into Afghanistan?

Answer: unanswerable

Problem: Bacteria:

Regardless of the type of metabolic process they employ, the majority of bacteria are able to take in raw materials only in the form of relatively small molecules, which enter the cell by diffusion or through molecular channels in cell membranes. The Planctomycetes are the exception (as they are in possessing membranes around their nuclear material). It has recently been shown that Gemmata obscuriglobus is able to take in large molecules via a process that in some ways resembles endocytosis, the process used by eukaryotic cells to engulf external items.

What part of bacteria cell is used during diffusion?
---
A:
molecular channels in cell membranes
