Problem: Vacuum is useful in a variety of processes and devices. Its first widespread use was in the incandescent light bulb to protect the filament from chemical degradation. The chemical inertness produced by a vacuum is also useful for electron beam welding, cold welding, vacuum packing and vacuum frying. Ultra-high vacuum is used in the study of atomically clean substrates, as only a very good vacuum preserves atomic-scale clean surfaces for a reasonably long time (on the order of minutes to days). High to ultra-high vacuum removes the obstruction of air, allowing particle beams to deposit or remove materials without contamination. This is the principle behind chemical vapor deposition, physical vapor deposition, and dry etching which are essential to the fabrication of semiconductors and optical coatings, and to surface science. The reduction of convection provides the thermal insulation of thermos bottles. Deep vacuum lowers the boiling point of liquids and promotes low temperature outgassing which is used in freeze drying, adhesive preparation, distillation, metallurgy, and process purging. The electrical properties of vacuum make electron microscopes and vacuum tubes possible, including cathode ray tubes. The elimination of air friction is useful for flywheel energy storage and ultracentrifuges.
What is produced by a vacuum and used in electron beam welding and vacuum frying?
The answer is the following: chemical inertness

During Hayek's years at the University of Vienna, Carl Menger's work on the explanatory strategy of social science and Friedrich von Wieser's commanding presence in the classroom left a lasting influence on him. Upon the completion of his examinations, Hayek was hired by Ludwig von Mises on the recommendation of Wieser as a specialist for the Austrian government working on the legal and economic details of the Treaty of Saint Germain. Between 1923 and 1924 Hayek worked as a research assistant to Prof. Jeremiah Jenks of New York University, compiling macroeconomic data on the American economy and the operations of the US Federal Reserve.
For whom did Hayek work upon being hired by Ludwig von Mises?
the Austrian government

Input: Canadian Armed Forces
All equipment must be suitable for a mixed-gender force. Combat helmets, rucksacks, combat boots, and flak jackets are designed to ensure women have the same level of protection and comfort as their male colleagues. The women's uniform is similar in design to the men's uniform, but conforms to the female figure, and is functional and practical. Women are also provided with an annual financial entitlement for the purchase of brassiere undergarments.

What is a requirement for equipment for the CAF?
Output: equipment must be suitable for a mixed-gender force

Input: Article: On February 12, 2014, the Los Angeles Times reported that Comcast sought to acquire Time Warner Cable in a deal valued at $45.2 billion. On February 13, it was reported that Time Warner Cable agreed to the acquisition. This was to add several metropolitan areas to the Comcast portfolio, such as New York City, Los Angeles, Dallas-Fort Worth, Cleveland, Columbus, Cincinnati, Charlotte, San Diego, and San Antonio. Time Warner Cable and Comcast aimed to merge into one company by the end of 2014 and both have praised the deal, emphasizing the increased capabilities of a combined telecommunications network, and to "create operating efficiencies and economies of scale".

Now answer this question: What was the value of the deal reported to be at the time?

Output: $45.2 billion

Article: The endonym is pronounced /k.ta/ in the Eastern Catalan dialects, and /ka.taa/ in the Western dialects. In the Valencian Community, the term valencia (/va.len.sia/) is frequently used instead. The names "Catalan" and "Valencian" are two names for the same language. See also status of Valencian below.

Question: What affect does different pronunciations in the two areas of Catalan speakers produce?
Ans: dialects

Input: Glacier
Glacial ice is the largest reservoir of freshwater on Earth. Many glaciers from temperate, alpine and seasonal polar climates store water as ice during the colder seasons and release it later in the form of meltwater as warmer summer temperatures cause the glacier to melt, creating a water source that is especially important for plants, animals and human uses when other sources may be scant. Within high altitude and Antarctic environments, the seasonal temperature difference is often not sufficient to release meltwater.

Do Earth's lakes or glaciers hold the most freshwater?
Output:
glaciers
