I know that the answer to the question "Which of the following was not the site of a governing junta: Chuquisaca, Supreme or Quito?" is in "The decolonization of the Americas was the process by which the countries in the Americas gained their independence from European rule. Decolonization began with a series of revolutions in the late 18th and early-to-mid-19th centuries. The Spanish American wars of independence were the numerous wars against Spanish rule in Spanish America that took place during the early 19th century, from 1808 until 1829, directly related to the Napoleonic French invasion of Spain. The conflict started with short-lived governing juntas established in Chuquisaca and Quito opposing the composition of the Supreme Central Junta of Seville.". Can you tell me what it is?
Ans: Supreme

I know that the answer to the question "How is high definition abbreviated?" is in "Analog tape recorders with bandwidth capable of recording analog HD signals, such as W-VHS recorders, are no longer produced for the consumer market and are both expensive and scarce in the secondary market.". Can you tell me what it is?
Ans: HD

I know that the answer to the question "What element comes into play?" is in "Semi-additive is the most common process: The unpatterned board has a thin layer of copper already on it. A reverse mask is then applied. (Unlike a subtractive process mask, this mask exposes those parts of the substrate that will eventually become the traces.) Additional copper is then plated onto the board in the unmasked areas; copper may be plated to any desired weight. Tin-lead or other surface platings are then applied. The mask is stripped away and a brief etching step removes the now-exposed bare original copper laminate from the board, isolating the individual traces. Some single-sided boards which have plated-through holes are made in this way. General Electric made consumer radio sets in the late 1960s using additive boards.". Can you tell me what it is?
Ans: copper

I know that the answer to the question "What makes a subgroup necessary?" is in "In the example above, the identity and the rotations constitute a subgroup R = {id, r1, r2, r3}, highlighted in red in the group table above: any two rotations composed are still a rotation, and a rotation can be undone by (i.e. is inverse to) the complementary rotations 270 for 90, 180 for 180, and 90 for 270 (note that rotation in the opposite direction is not defined). The subgroup test is a necessary and sufficient condition for a subset H of a group G to be a subgroup: it is sufficient to check that g1h H for all elements g, h H. Knowing the subgroups is important in understanding the group as a whole.d["]". Can you tell me what it is?
Ans: Knowing the subgroups is important in understanding the group as a whole
