Input: Read this: 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.
Question: What is still considered an art today?

Output: unanswerable


QUES: One wave of the population boom ended abruptly in the mid-1980s, as oil prices fell precipitously. The space industry also suffered in 1986 after the Space Shuttle Challenger disintegrated shortly after launch. There was a cutback in some activities for a period. In the late 1980s, the city's economy suffered from the nationwide recession. After the early 1990s recession, Houston made efforts to diversify its economy by focusing on aerospace and health care/biotechnology, and reduced its dependence on the petroleum industry. Since the increase of oil prices in the 2000s, the petroleum industry has again increased its share of the local economy.

What did Houston focus on after the 1990s recession to improve its economy?
What is the answer?
ANS: aerospace and health care


QUES: The Sahara (Arabic: الصحراء الكبرى‎, aṣ-ṣaḥrāʾ al-kubrā , 'the Greatest Desert') is the largest hot desert in the world. It is the third largest desert after Antarctica and the Arctic. Its surface area of 9,400,000 square kilometres (3,600,000 sq mi)[citation needed]—including the Libyan Desert—is comparable to the respective land areas of China or the United States. The desert comprises much of the land found within North Africa, excluding the fertile coastal region situated against the Mediterranean Sea, the Atlas Mountains of the Maghreb, and the Nile Valley of Egypt and Sudan. The Sahara stretches from the Red Sea in the east and the Mediterranean in the north, to the Atlantic Ocean in the west, where the landscape gradually transitions to a coastal plain. To the south, it is delimited by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and Sudan Region of Sub-Saharan Africa. The Sahara can be divided into several regions, including the western Sahara, the central Ahaggar Mountains, the Tibesti Mountains, the Aïr Mountains, the Ténéré desert, and the Libyan Desert. Its name is derived from the plural Arabic language word for desert (صحارى ṣaḥārā  [ˈsˤɑħɑːrɑː]).

Uranium is used as a colorant in uranium glass producing orange-red to lemon yellow hues. It was also used for tinting and shading in early photography. The 1789 discovery of uranium in the mineral pitchblende is credited to Martin Heinrich Klaproth, who named the new element after the planet Uranus. Eugène-Melchior Péligot was the first person to isolate the metal and its radioactive properties were discovered in 1896 by Henri Becquerel. Research by Otto Hahn, Lise Meitner, Enrico Fermi and others, such as J. Robert Oppenheimer starting in 1934 led to its use as a fuel in the nuclear power industry and in Little Boy, the first nuclear weapon used in war. An ensuing arms race during the Cold War between the United States and the Soviet Union produced tens of thousands of nuclear weapons that used uranium metal and uranium-derived plutonium-239. The security of those weapons and their fissile material following the breakup of the Soviet Union in 1991 is an ongoing concern for public health and safety. See Nuclear proliferation.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the first nuclear weapon used in a war called?
Ah, so.. Little Boy


Question: In 1976, contemporaneously with Woodson and Roberts, the Court decided Gregg v. Georgia and upheld a procedure in which the trial of capital crimes was bifurcated into guilt-innocence and sentencing phases. At the first proceeding, the jury decides the defendant's guilt; if the defendant is innocent or otherwise not convicted of first-degree murder, the death penalty will not be imposed. At the second hearing, the jury determines whether certain statutory aggravating factors exist, whether any mitigating factors exist, and, in many jurisdictions, weigh the aggravating and mitigating factors in assessing the ultimate penalty – either death or life in prison, either with or without parole.
Try to answer this question if possible:  Along with aggravating factors, what other factors are considered at the third hearing?
Answer: unanswerable


Question: In the mid 1970s, various American groups (some with ties to Downtown Manhattan's punk scene, including Television and Suicide) had begun expanding on the vocabulary of punk music. Midwestern groups such as Pere Ubu and Devo drew inspiration from the region's derelict industrial environments, employing conceptual art techniques, musique concrète and unconventional verbal styles that would presage the post-punk movement by several years. A variety of subsequent groups, including New York-based Talking Heads and Boston-based Mission of Burma, combined elements of punk with art school sensibilities. In 1978, the former band began a series of collaborations with British ambient pioneer and ex-Roxy Music member Brian Eno, experimenting with Dada-influenced lyrical techniques, dance music, and African polyrhythms. San Francisco's vibrant post-punk scene was centered around such groups as Chrome, the Residents and Tuxedomoon, who incorporated multimedia experimentation, film and ideas from Antonin Artaud's Theater of Cruelty.
Try to answer this question if possible: What did Pere and Devo draw inspiration for their music from?
Answer:
derelict industrial environments
