Problem: Appointments to the Order of the British Empire were discontinued in those Commonwealth realms that established a national system of honours and awards such as the Order of Australia, the Order of Canada, and the New Zealand Order of Merit. In many of these systems, the different levels of award and honour reflect the Imperial system they replaced. Canada, Australia, and New Zealand all have (in increasing level of precedence) Members of, Officers of, and Companions to (rather than Commanders of) their respective orders, with both Australia and New Zealand having Knights and Dames as their highest classes.
What were the highest class?
The answer is the following: Knights and Dames

In military affairs, the use of infantry with specialised roles increased. Along with the still-dominant heavy cavalry, armies often included mounted and infantry crossbowmen, as well as sappers and engineers. Crossbows, which had been known in Late Antiquity, increased in use partly because of the increase in siege warfare in the 10th and 11th centuries.[AB] The increasing use of crossbows during the 12th and 13th centuries led to the use of closed-face helmets, heavy body armour, as well as horse armour. Gunpowder was known in Europe by the mid-13th century with a recorded use in European warfare by the English against the Scots in 1304, although it was merely used as an explosive and not as a weapon. Cannon were being used for sieges in the 1320s, and hand-held guns were in use by the 1360s.
In what century did Europeans become aware of gunpowder?
13th

Input: Printed circuit board
Surface-mount technology emerged in the 1960s, gained momentum in the early 1980s and became widely used by the mid-1990s. Components were mechanically redesigned to have small metal tabs or end caps that could be soldered directly onto the PCB surface, instead of wire leads to pass through holes. Components became much smaller and component placement on both sides of the board became more common than with through-hole mounting, allowing much smaller PCB assemblies with much higher circuit densities. Surface mounting lends itself well to a high degree of automation, reducing labor costs and greatly increasing production rates. Components can be supplied mounted on carrier tapes. Surface mount components can be about one-quarter to one-tenth of the size and weight of through-hole components, and passive components much cheaper; prices of semiconductor surface mount devices (SMDs) are determined more by the chip itself than the package, with little price advantage over larger packages. Some wire-ended components, such as 1N4148 small-signal switch diodes, are actually significantly cheaper than SMD equivalents.

When did surface-mount become a commonly used manufacturing process?
Output: mid-1990s

Input: Article: Before the 20th century, the term matter included ordinary matter composed of atoms and excluded other energy phenomena such as light or sound. This concept of matter may be generalized from atoms to include any objects having mass even when at rest, but this is ill-defined because an object's mass can arise from its (possibly massless) constituents' motion and interaction energies. Thus, matter does not have a universal definition, nor is it a fundamental concept in physics today. Matter is also used loosely as a general term for the substance that makes up all observable physical objects.

Now answer this question: What term is used for the substance that composes all observable physical objects?

Output: matter

Article: Among Richmond's most interesting architectural features is its Cast-iron architecture. Second only to New Orleans in its concentration of cast iron work, the city is home to a unique collection of cast iron porches, balconies, fences, and finials. Richmond's position as a center of iron production helped to fuel its popularity within the city. At the height of production in the 1890, 25 foundries operated in the city employing nearly 3,500 metal workers. This number is seven times the number of general construction workers being employed in Richmond at the time which illustrates the importance of its iron exports. Porches and fences in urban neighborhoods such as Jackson Ward, Church Hill, and Monroe Ward are particularly elaborate, often featuring ornate iron casts never replicated outside of Richmond. In some cases cast were made for a single residential or commercial application.

Question: What United States city has the most cast iron architecture?
Ans: New Orleans

Input: Myanmar
In 1988, unrest over economic mismanagement and political oppression by the government led to widespread pro-democracy demonstrations throughout the country known as the 8888 Uprising. Security forces killed thousands of demonstrators, and General Saw Maung staged a coup d'etat and formed the State Law and Order Restoration Council (SLORC). In 1989, SLORC declared martial law after widespread protests. The military government finalised plans for People's Assembly elections on 31 May 1989. SLORC changed the country's official English name from the "Socialist Republic of the Union of Burma" to the "Union of Myanmar" in 1989.

What are the 1988 demonstrations in Burma called?
Output:
8888 Uprising
