Input: Article: The sensitivity of Earth-based infrared telescopes is significantly limited by water vapor in the atmosphere, which absorbs a portion of the infrared radiation arriving from space outside of selected atmospheric windows. This limitation can be partially alleviated by placing the telescope observatory at a high altitude, or by carrying the telescope aloft with a balloon or an aircraft. Space telescopes do not suffer from this handicap, and so outer space is considered the ideal location for infrared astronomy.

Now answer this question: What limits the sensitivity of infrared telescopes on Earth?

Output: water vapor in the atmosphere


Article: The current economy of the city is basically newly developed based on the past. Service industries are dominating, accounting for about 60 percent of the GDP of the city, and financial industry, culture industry and tourism industry are top 3 of them. Industries of information technology, energy saving and environmental protection, new energy, smart power grid and intelligent equipment manufacturing have become pillar industries. Big private firms include Suning, Yurun, Sanpower, Fuzhong, Hiteker, 5stars, Jinpu, Tiandi, CTTQ Pharmaceutical and Simcere Pharmaceutical. Big state-owned firms include Panda Electronics, Yangzi Petrochemical, Jinling Petrochemical, Nanjing Chemical, Nanjing Steel, Jincheng Motors, Jinling Pharmaceutical, Chenguang and NARI. The city has also attracted foreign investment, multinational firms such as Siemens, Ericsson, Volkswagen, Iveco, A.O. Smith, and Sharp have established their lines, and a number of multinationals such as Ford, IBM, Lucent, Samsung and SAP established research center there. Many China-based leading firms such as Huawei, ZTE and Lenovo have key R & D institutes in the city. Nanjing is an industrial technology research and development hub, hosting many R & D centers and institutions, especially in areas of electronics technology, information technology, computer software, biotechnology and pharmaceutical technology and new material technology.

Question: The top 3 industries in Nanjing are?
Ans: financial industry, culture industry and tourism industry


Here is a question about this article: Whereas the chromosomes of prokaryotes are relatively gene-dense, those of eukaryotes often contain regions of DNA that serve no obvious function. Simple single-celled eukaryotes have relatively small amounts of such DNA, whereas the genomes of complex multicellular organisms, including humans, contain an absolute majority of DNA without an identified function. This DNA has often been referred to as "junk DNA". However, more recent analyses suggest that, although protein-coding DNA makes up barely 2% of the human genome, about 80% of the bases in the genome may be expressed, so the term "junk DNA" may be a misnomer.
What is the answer to this question: What is referred to as "junk DNA"?
****
So... DNA without an identified function


The problem: Answer a question about this article:
Improvisation once played an important role in classical music. A remnant of this improvisatory tradition in classical music can be heard in the cadenza, a passage found mostly in concertos and solo works, designed to allow skilled performers to exhibit their virtuoso skills on the instrument. Traditionally this was improvised by the performer; however, it is often written for (or occasionally by) the performer beforehand. Improvisation is also an important aspect in authentic performances of operas of Baroque era and of bel canto (especially operas of Vincenzo Bellini), and is best exemplified by the da capo aria, a form by which famous singers typically perform variations of the thematic matter of the aria in the recapitulation section ('B section' / the 'da capo' part). An example is Beverly Sills' complex, albeit pre-written, variation of Da tempeste il legno infranto from Händel's Giulio Cesare.
What once played an important role in classical music?
****
The answer: Improvisation


Problem: Please answer a question about the following article about George VI:
In 1940, Winston Churchill replaced Neville Chamberlain as Prime Minister, though personally George would have preferred to appoint Lord Halifax. After the King's initial dismay over Churchill's appointment of Lord Beaverbrook to the Cabinet, he and Churchill developed "the closest personal relationship in modern British history between a monarch and a Prime Minister". Every Tuesday for four and a half years from September 1940, the two men met privately for lunch to discuss the war in secret and with frankness.
What day of the week did Churchill and the King meet?
A: Tuesday

The study of plants is vital because they underpin almost all animal life on Earth by generating a large proportion of the oxygen and food that provide humans and other organisms with aerobic respiration with the chemical energy they need to exist. Plants, algae and cyanobacteria are the major groups of organisms that carry out photosynthesis, a process that uses the energy of sunlight to convert water and carbon dioxide into sugars that can be used both as a source of chemical energy and of organic molecules that are used in the structural components of cells. As a by-product of photosynthesis, plants release oxygen into the atmosphere, a gas that is required by nearly all living things to carry out cellular respiration. In addition, they are influential in the global carbon and water cycles and plant roots bind and stabilise soils, preventing soil erosion. Plants are crucial to the future of human society as they provide food, oxygen, medicine, and products for people, as well as creating and preserving soil.

What is used to rebuild cells?
Answer:
organic molecules
