Problem: Mexico City:

While the Federal District was ruled by the federal government through an appointed governor, the municipalities within it were autonomous, and this duality of powers created tension between the municipalities and the federal government for more than a century. In 1903, Porfirio Diaz largely reduced the powers of the municipalities within the Federal District. Eventually, in December 1928, the federal government decided to abolish all the municipalities of the Federal District. In place of the municipalities, the Federal District was divided into one "Central Department" and 13 delegaciones (boroughs) administered directly by the government of the Federal District. The Central Department was integrated by the former municipalities of Mexico City, Tacuba, Tacubaya and Mixcoac.

Who led Mexico City?

A: an appointed governor

Problem: Molecules of carbohydrates and fats consist of carbon, hydrogen, and oxygen atoms. Carbohydrates range from simple monosaccharides (glucose, fructose, galactose) to complex polysaccharides (starch). Fats are triglycerides, made of assorted fatty acid monomers bound to a glycerol backbone. Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body. Protein molecules contain nitrogen atoms in addition to carbon, oxygen, and hydrogen. The fundamental components of protein are nitrogen-containing amino acids, some of which are essential in the sense that humans cannot make them internally. Some of the amino acids are convertible (with the expenditure of energy) to glucose and can be used for energy production, just as ordinary glucose, in a process known as gluconeogenesis. By breaking down existing protein, the carbon skeleton of the various amino acids can be metabolized to intermediates in cellular respiration; the remaining ammonia is discarded primarily as urea in urine. This occurs normally only during prolonged starvation.
Which element do the amino acids that make up the core component of protein have in common?
---
Answer: nitrogen

As for Mac OS, System 7 was a 32-bit rewrite from Pascal to C++ that introduced virtual memory and improved the handling of color graphics, as well as memory addressing, networking, and co-operative multitasking. Also during this time, the Macintosh began to shed the "Snow White" design language, along with the expensive consulting fees they were paying to Frogdesign. Apple instead brought the design work in-house by establishing the Apple Industrial Design Group, becoming responsible for crafting a new look for all Apple products.
Which Mac is known for improving the handling of non-color graphics?
A: unanswerable

Context and question: By 26 March, the growing refusal of soldiers to fire into the largely nonviolent protesting crowds turned into a full-scale tumult, and resulted into thousands of soldiers putting down their arms and joining the pro-democracy movement. That afternoon, Lieutenant Colonel Amadou Toumani Toure announced on the radio that he had arrested the dictatorial president, Moussa Traore. As a consequence, opposition parties were legalized and a national congress of civil and political groups met to draft a new democratic constitution to be approved by a national referendum.
The non violent protesting led the soldiers to engage in what type of behavior?
Answer: refusal of soldiers to fire

Question: The Mildred Lane Kemper Art Museum, established in 1881, is one of the oldest teaching museums in the country. The collection includes works from 19th, 20th, and 21st century American and European artists, including George Caleb Bingham, Thomas Cole, Pablo Picasso, Max Ernst, Alexander Calder, Jackson Pollock, Rembrandt, Robert Rauschenberg, Barbara Kruger, and Christian Boltanski. Also in the complex is the 3,000 sq ft (300 m2) Newman Money Museum. In October 2006, the Kemper Art Museum moved from its previous location, Steinberg Hall, into a new facility designed by former faculty member Fumihiko Maki. Interestingly, the new Kemper Art Museum is located directly across from Steinberg Hall, which was Maki's very first commission in 1959.
Is there an answer to this question: From what centuries does the Mildred Lane Kemper Art Museum have collections?

Answer: 19th, 20th, and 21st century
