The problem: Answer a question about this article:
The instruments currently used in most classical music were largely invented before the mid-19th century (often much earlier) and codified in the 18th and 19th centuries. They consist of the instruments found in an orchestra or in a concert band, together with several other solo instruments (such as the piano, harpsichord, and organ). The symphony orchestra is the most widely known medium for classical music and includes members of the string, woodwind, brass, and percussion families of instruments. The concert band consists of members of the woodwind, brass, and percussion families. It generally has a larger variety and amount of woodwind and brass instruments than the orchestra but does not have a string section. However, many concert bands use a double bass. The vocal practices changed a great deal over the classical period, from the single line monophonic Gregorian chant done by monks in the Medieval period to the complex, polyphonic choral works of the Renaissance and subsequent periods, which used multiple independent vocal melodies at the same time.
What does a symphony orchestra have that is missing from a concert band?
****
The answer: a string section


Problem: Please answer a question about the following article about Religion in ancient Rome:
By the end of the regal period Rome had developed into a city-state, with a large plebeian, artisan class excluded from the old patrician gentes and from the state priesthoods. The city had commercial and political treaties with its neighbours; according to tradition, Rome's Etruscan connections established a temple to Minerva on the predominantly plebeian Aventine; she became part of a new Capitoline triad of Jupiter, Juno and Minerva, installed in a Capitoline temple, built in an Etruscan style and dedicated in a new September festival, Epulum Jovis. These are supposedly the first Roman deities whose images were adorned, as if noble guests, at their own inaugural banquet.
With whom did Rome have alliances at the end of the regal period?
A: neighbours


Question: Read this and answer the question

The city shares a 15-mile (24 km) border with Mexico that includes two border crossings. San Diego hosts the busiest international border crossing in the world, in the San Ysidro neighborhood at the San Ysidro Port of Entry. A second, primarily commercial border crossing operates in the Otay Mesa area; it is the largest commercial crossing on the California-Baja California border and handles the third-highest volume of trucks and dollar value of trade among all United States-Mexico land crossings.

Where is San Diego's border crossing?
Answer: the San Ysidro neighborhood at the San Ysidro Port of Entry


Problem: Tracks include Tucson Raceway Park and Rillito Downs. Tucson Raceway Park hosts NASCAR-sanctioned auto racing events and is one of only two asphalt short tracks in Arizona. Rillito Downs is an in-town destination on weekends in January and February each year. This historic track held the first organized quarter horse races in the world, and they are still racing there. The racetrack is threatened by development. The Moltacqua racetrack, was another historic horse racetrack located on what is now Sabino Canyon Road and Vactor Ranch Trail, but it no longer exists.
What kind of races does Rillito Downs hold?
The answer is the following: quarter horse races


Modern archaeology has led to the discovery of Han artwork portraying inventions which were otherwise absent in Han literary sources. As observed in Han miniature tomb models, but not in literary sources, the crank handle was used to operate the fans of winnowing machines that separated grain from chaff. The odometer cart, invented during Han, measured journey lengths, using mechanical figures banging drums and gongs to indicate each distance traveled. This invention is depicted in Han artwork by the 2nd century AD, yet detailed written descriptions were not offered until the 3rd century AD. Modern archaeologists have also unearthed specimens of devices used during the Han dynasty, for example a pair of sliding metal calipers used by craftsmen for making minute measurements. These calipers contain inscriptions of the exact day and year they were manufactured. These tools are not mentioned in any Han literary sources.
During which period was the odometer cart first created?
Han


Here is a question about this article: Moving to reduce Italian influence, in October 1970 all Italian-owned assets were expropriated and the 12,000-strong Italian community expelled from Libya alongside a smaller number of Jews. The day became a national holiday. Aiming to reduce NATO power in the Mediterranean, in 1971 Libya requested that Malta cease to allow NATO to use its land for a military base, in turn offering them foreign aid. Compromising, Malta's government continued allowing NATO use of the island, but only on the condition that they would not use it for launching attacks on Arab territory. Orchestrating a military build-up, the RCC began purchasing weapons from France and the Soviet Union. The commercial relationship with the latter led to an increasingly strained relationship with the U.S., who were then engaged in the Cold War with the Soviets.
What is the answer to this question: How many Italians lived in Libya prior to October of 1970?
****
So...
12,000
