Problem: 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.

Why did it make sense to spend time fixing cloth?

A: worth more than labor

Problem: Over three quarters of the student body has some proficiency in a second language (numbering 107 languages in total). This is partially due to the fact that 45 percent of the student body at BYU has been missionaries for LDS Church, and many of them learned a foreign language as part of their mission assignment. During any given semester, about one-third of the student body is enrolled in foreign language classes, a rate nearly four times the national average. BYU offers courses in over 60 different languages, many with advanced courses that are seldom offered elsewhere. Several of its language programs are the largest of their kind in the nation, the Russian program being one example. The university was selected by the United States Department of Education as the location of the national Middle East Language Resource Center, making the school a hub for experts on that region. It was also selected as a Center for International Business Education Research, a function of which is to train business employees in international languages and relations.
What can be attributed to BYU's high percentage of second language proficient students?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Buddhism may have spread only slowly in India until the time of the Mauryan emperor Ashoka, who was a public supporter of the religion. The support of Asoka and his descendants led to the construction of more stupas (Buddhist religious memorials) and to efforts to spread Buddhism throughout the enlarged Maurya empire and even into neighboring landsparticularly to the Iranian-speaking regions of Afghanistan and Central Asia, beyond the Mauryas' northwest border, and to the island of Sri Lanka south of India. These two missions, in opposite directions, would ultimately lead, in the first case to the spread of Buddhism into China, and in the second case, to the emergence of Theravada Buddhism and its spread from Sri Lanka to the coastal lands of Southeast Asia.
What does stupas mean in English?
A: Buddhist religious memorials

Context and question: Local anesthetic injections into the nerves or sensitive areas of the stump may relieve pain for days, weeks, or sometimes permanently, despite the drug wearing off in a matter of hours; and small injections of hypertonic saline into the soft tissue between vertebrae produces local pain that radiates into the phantom limb for ten minutes or so and may be followed by hours, weeks or even longer of partial or total relief from phantom pain. Vigorous vibration or electrical stimulation of the stump, or current from electrodes surgically implanted onto the spinal cord, all produce relief in some patients.
What does vigorous stimulation provide?
Answer: unanswerable

Question: Jonathan Bellman writes that modern concert performance styleset in the "conservatory" tradition of late 19th- and 20th-century music schools, and suitable for large auditoria or recordingsmilitates against what is known of Chopin's more intimate performance technique. The composer himself said to a pupil that "concerts are never real music, you have to give up the idea of hearing in them all the most beautiful things of art." Contemporary accounts indicate that in performance, Chopin avoided rigid procedures sometimes incorrectly attributed to him, such as "always crescendo to a high note", but that he was concerned with expressive phrasing, rhythmic consistency and sensitive colouring. Berlioz wrote in 1853 that Chopin "has created a kind of chromatic embroidery ... whose effect is so strange and piquant as to be impossible to describe ... virtually nobody but Chopin himself can play this music and give it this unusual turn". Hiller wrote that "What in the hands of others was elegant embellishment, in his hands became a colourful wreath of flowers."
Is there an answer to this question: What did Chopin tell a student is given up in concerts?

Answer: hearing in them all the most beautiful things of art

Question: Ibn Sina created an extensive corpus of works during what is commonly known as the Islamic Golden Age, in which the translations of Greco-Roman, Persian, and Indian texts were studied extensively. Greco-Roman (Mid- and Neo-Platonic, and Aristotelian) texts translated by the Kindi school were commented, redacted and developed substantially by Islamic intellectuals, who also built upon Persian and Indian mathematical systems, astronomy, algebra, trigonometry and medicine. The Samanid dynasty in the eastern part of Persia, Greater Khorasan and Central Asia as well as the Buyid dynasty in the western part of Persia and Iraq provided a thriving atmosphere for scholarly and cultural development. Under the Samanids, Bukhara rivaled Baghdad as a cultural capital of the Islamic world.
Is there an answer to this question: What city was the cultural capital of the world?

Answer:
unanswerable
