Problem: Paper:

In Europe, and other regions using the ISO 216 paper sizing system, the weight is expressed in grammes per square metre (g/m2 or usually just g) of the paper. Printing paper is generally between 60 g and 120 g. Anything heavier than 160 g is considered card. The weight of a ream therefore depends on the dimensions of the paper and its thickness.

Besides thickness, what attribute is used in stating the weight of a ream in Asia?

A: unanswerable

Context and question: The Royal School of Mines was established by Sir Henry de la Beche in 1851, developing from the Museum of Economic Geology, a collection of minerals, maps and mining equipment. He created a school which laid the foundations for the teaching of science in the country, and which has its legacy today at Imperial. Prince Albert was a patron and supporter of the later developments in science teaching, which led to the Royal College of Chemistry becoming part of the Royal School of Mines, to the creation of the Royal College of Science and eventually to these institutions becoming part of his plan for South Kensington being an educational region.
Who wanted to make North Kensington an education region?
Answer: unanswerable


Question: A plethora of anti-aircraft gun systems of smaller calibre were available to the German Wehrmacht combined forces, and among them the 1940-origin Flakvierling quadruple-20 mm-gun antiaircraft weapon system was one of the most often-seen weapons, seeing service on both land and sea. The similar Allied smaller-calibre air-defence weapons systems of the American forces were also quite capable, although they receive little attention. Their needs could cogently be met with smaller-calibre ordnance beyond using the usual singly-mounted M2 .50 caliber machine gun atop a tank's turret, as four of the ground-used "heavy barrel" (M2HB) guns were mounted together on the American Maxson firm's M45 Quadmount weapons system (as a direct answer to the Flakvierling),which were often mounted on the back of a half-track to form the Half Track, M16 GMC, Anti-Aircraft. Although of less power than Germany's 20 mm systems, the typical 4 or 5 combat batteries of an Army AAA battalion were often spread many kilometers apart from each other, rapidly attaching and detaching to larger ground combat units to provide welcome defence from enemy aircraft.
Is there an answer to this question: What weapons system did American troops use but received minute attention?

Answer: Allied smaller-calibre air-defence weapons systems
