Input: Read this: A number of technologies allow asphalt/bitumen to be mixed at much lower temperatures. These involve mixing with petroleum solvents to form "cutbacks" with reduced melting point, or mixtures with water to turn the asphalt/bitumen into an emulsion. Asphalt emulsions contain up to 70% asphalt/bitumen and typically less than 1.5% chemical additives. There are two main types of emulsions with different affinity for aggregates, cationic and anionic. Asphalt emulsions are used in a wide variety of applications. Chipseal involves spraying the road surface with asphalt emulsion followed by a layer of crushed rock, gravel or crushed slag. Slurry seal involves the creation of a mixture of asphalt emulsion and fine crushed aggregate that is spread on the surface of a road. Cold-mixed asphalt can also be made from asphalt emulsion to create pavements similar to hot-mixed asphalt, several inches in depth and asphalt emulsions are also blended into recycled hot-mix asphalt to create low-cost pavements.
Question: What does mixing bitumen with water create?

Output: emulsion


QUES: Scientific and technological research activities in Portugal are mainly conducted within a network of R&D units belonging to public universities and state-managed autonomous research institutions like the INETI – Instituto Nacional de Engenharia, Tecnologia e Inovação and the INRB – Instituto Nacional dos Recursos Biológicos. The funding and management of this research system is mainly conducted under the authority of the Ministry of Science, Technology and Higher Education (MCTES) itself and the MCTES's Fundação para a Ciência e Tecnologia (FCT). The largest R&D units of the public universities by volume of research grants and peer-reviewed publications, include biosciences research institutions like the Instituto de Medicina Molecular, the Centre for Neuroscience and Cell Biology, the IPATIMUP, the Instituto de Biologia Molecular e Celular and the Abel Salazar Biomedical Sciences Institute.

In what type of network are most scientific research studies conducted in Portugal?
What is the answer?
ANS: R&D units belonging to public universities and state-managed autonomous research institutions


QUES: Tandem repeats are usually caused by slippage during replication, unequal crossing-over and gene conversion, satellite DNA and microsatellites are forms of tandem repeats in the genome. Although tandem repeats count for a significant proportion in genome, the largest proportion in mammalian is the other type, interspersed repeats.
What causes interspersed repeats?

ANS: unanswerable


Switzerland's trade was blockaded by both the Allies and by the Axis. Economic cooperation and extension of credit to the Third Reich varied according to the perceived likelihood of invasion and the availability of other trading partners. Concessions reached a peak after a crucial rail link through Vichy France was severed in 1942, leaving Switzerland completely surrounded by the Axis. Over the course of the war, Switzerland interned over 300,000 refugees and the International Red Cross, based in Geneva, played an important part during the conflict. Strict immigration and asylum policies as well as the financial relationships with Nazi Germany raised controversy, but not until the end of the 20th century.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was severed in 1942, leaving Switzerland completely surrounded by the Axis?
Ah, so.. a crucial rail link through Vichy France


Question: This process begins when the user inputs a Uniform Resource Locator (URL), for example http://en.wikipedia.org/, into the browser. The prefix of the URL, the Uniform Resource Identifier or URI, determines how the URL will be interpreted. The most commonly used kind of URI starts with http: and identifies a resource to be retrieved over the Hypertext Transfer Protocol (HTTP). Many browsers also support a variety of other prefixes, such as https: for HTTPS, ftp: for the File Transfer Protocol, and file: for local files. Prefixes that the web browser cannot directly handle are often handed off to another application entirely. For example, mailto: URIs are usually passed to the user's default e-mail application, and news: URIs are passed to the user's default newsgroup reader.
Try to answer this question if possible: What does URL stand for?
Answer: Uniform Resource Locator


Context and question: The moratorium ended on January 17, 1977 with the shooting of Gary Gilmore by firing squad in Utah. The first use of the electric chair after the moratorium was the electrocution of John Spenkelink in Florida on May 25, 1979. The first use of the gas chamber after the moratorium was the gassing of Jesse Bishop in Nevada on October 22, 1979. The first use of the gallows after the moratorium was the hanging of Westley Allan Dodd in Washington on January 5, 1993. The first use of lethal injection was on December 7, 1982, when Charles Brooks, Jr., was executed in Texas.
 On what date was John Spenkelink freed?
Answer:
unanswerable
