Problem: The United States Army is made up of three components: the active component, the Regular Army; and two reserve components, the Army National Guard and the Army Reserve. Both reserve components are primarily composed of part-time soldiers who train once a month, known as battle assemblies or unit training assemblies (UTAs), and conduct two to three weeks of annual training each year. Both the Regular Army and the Army Reserve are organized under Title 10 of the United States Code, while the National Guard is organized under Title 32. While the Army National Guard is organized, trained and equipped as a component of the U.S. Army, when it is not in federal service it is under the command of individual state and territorial governors; the District of Columbia National Guard, however, reports to the U.S. President, not the district's mayor, even when not federalized. Any or all of the National Guard can be federalized by presidential order and against the governor's wishes.
Who does the D.C. National Guard report to?
---
Answer: the U.S. President

Context and question: The following sulfonylureas have been commercialized for weed control: amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, ethoxysulfuron, flazasulfuron, flupyrsulfuron-methyl-sodium, halosulfuron-methyl, imazosulfuron, nicosulfuron, oxasulfuron, primisulfuron-methyl, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl Sulfosulfuron, terbacil, bispyribac-sodium, cyclosulfamuron, and pyrithiobac-sodium. Nicosulfuron, triflusulfuron methyl, and chlorsulfuron are broad-spectrum herbicides that kill plants by inhibiting the enzyme acetolactate synthase. In the 1960s, more than 1 kg/ha (0.89 lb/acre) crop protection chemical was typically applied, while sulfonylureates allow as little as 1% as much material to achieve the same effect.
What is acetolactate synthase classified as when used on plants?
Answer: unanswerable


Question: In the 16th century political and religious changes altered the attitude of historians towards John. Tudor historians were generally favourably inclined towards the king, focusing on John's opposition to the Papacy and his promotion of the special rights and prerogatives of a king. Revisionist histories written by John Foxe, William Tyndale and Robert Barnes portrayed John as an early Protestant hero, and John Foxe included the king in his Book of Martyrs. John Speed's Historie of Great Britaine in 1632 praised John's "great renown" as a king; he blamed the bias of medieval chroniclers for the king's poor reputation.
Is there an answer to this question: What praised John's "great renown" as a king?

Answer: John Speed's Historie of Great Britaine
