Input: Article: In the 15th century the dome was added and the naves extended back of the choir, uniting the building to the tower and forming a main entrance. Archbishop Luis Alfonso de los Cameros began the building of the main chapel in 1674; the walls were decorated with marbles and bronzes in the Baroque style of that period. At the beginning of the 18th century the German Conrad Rudolphus built the facade of the main entrance. The other two doors lead into the transept; one, that of the Apostles in pure pointed Gothic, dates from the 14th century, the other is that of the Palau. The additions made to the back of the cathedral detract from its height. The 18th-century restoration rounded the pointed arches, covered the Gothic columns with Corinthian pillars, and redecorated the walls. The dome has no lantern, its plain ceiling being pierced by two large side windows. There are four chapels on either side, besides that at the end and those that open into the choir, the transept, and the sanctuary. It contains many paintings by eminent artists. A silver reredos, which was behind the altar, was carried away in the war of 1808, and converted into coin to meet the expenses of the campaign. There are two paintings by Francisco Goya in the San Francesco chapel. Behind the Chapel of the Blessed Sacrament is a small Renaissance chapel built by Calixtus III. Beside the cathedral is the chapel dedicated to the Our Lady of the Forsaken (Virgen de los desamparados or Mare de Deu dels Desamparats).

Now answer this question: Who painted the pictures that are in the San Francesco chapel?

Output: Francisco Goya

Article: According to Dr. Carlos Moore, resident scholar at Brazil's University of the State of Bahia, in the 21st century Afro-multiracials in the Arab world, including Arabs in North Africa, self-identify in ways that resemble multi-racials in Latin America. He claims that black-looking Arabs, much like black-looking Latin Americans, consider themselves white because they have some distant white ancestry.

Question: Why would a black-looking Arab consider himself white?
Ans: because they have some distant white ancestry.

The problem: Answer a question about this article:
In quantum mechanics and quantum field theory, the vacuum is defined as the state (that is, the solution to the equations of the theory) with the lowest possible energy (the ground state of the Hilbert space). In quantum electrodynamics this vacuum is referred to as 'QED vacuum' to distinguish it from the vacuum of quantum chromodynamics, denoted as QCD vacuum. QED vacuum is a state with no matter particles (hence the name), and also no photons. As described above, this state is impossible to achieve experimentally. (Even if every matter particle could somehow be removed from a volume, it would be impossible to eliminate all the blackbody photons.) Nonetheless, it provides a good model for realizable vacuum, and agrees with a number of experimental observations as described next.
What is a QCD?

The answer: vacuum of quantum chromodynamics,

Problem: Please answer a question about the following article about Clothing:
In past times, mending was an art. A meticulous tailor or seamstress could mend rips with thread raveled from hems and seam edges so skillfully that the tear was practically invisible. When the raw material cloth was worth more than labor, it made sense to expend labor in saving it. Today clothing is considered a consumable item. Mass-manufactured clothing is less expensive than the labor required to repair it. Many people buy a new piece of clothing rather than spend time mending. The thrifty still replace zippers and buttons and sew up ripped hems.
What is clothing considered today?
A: a consumable item

Question: Read this and answer the question

Dog meat is consumed in some East Asian countries, including Korea, China, and Vietnam, a practice that dates back to antiquity. It is estimated that 1316 million dogs are killed and consumed in Asia every year. Other cultures, such as Polynesia and pre-Columbian Mexico, also consumed dog meat in their history. However, Western, South Asian, African, and Middle Eastern cultures, in general, regard consumption of dog meat as taboo. In some places, however, such as in rural areas of Poland, dog fat is believed to have medicinal propertiesbeing good for the lungs for instance. Dog meat is also consumed in some parts of Switzerland. Proponents of eating dog meat have argued that placing a distinction between livestock and dogs is western hypocrisy, and that there is no difference with eating the meat of different animals.

The West, South Asia and Middle East think eating dogs is what?
Answer:
taboo
