Context and question: People can be exposed to asphalt in the workplace by breathing in fumes or skin absorption. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 5 mg/m3 over a 15-minute period. Asphalt is basically an inert material that must be heated or diluted to a point where it becomes workable for the production of materials for paving, roofing, and other applications. In examining the potential health hazards associated with asphalt, the International Agency for Research on Cancer (IARC) determined that it is the application parameters, predominantly temperature, that effect occupational exposure and the potential bioavailable carcinogenic hazard/risk of the asphalt emissions. In particular, temperatures greater than 199 °C (390 °F), were shown to produce a greater exposure risk than when asphalt was heated to lower temperatures, such as those typically used in asphalt pavement mix production and placement.
Temperatures higher than 300 degrees Celsius where shown to do what?
Answer: unanswerable
Context and question: Most beers are cleared of yeast by filtering when packaged in bottles and cans. However, bottle conditioned beers retain some yeast—either by being unfiltered, or by being filtered and then reseeded with fresh yeast. It is usually recommended that the beer be poured slowly, leaving any yeast sediment at the bottom of the bottle. However, some drinkers prefer to pour in the yeast; this practice is customary with wheat beers. Typically, when serving a hefeweizen wheat beer, 90% of the contents are poured, and the remainder is swirled to suspend the sediment before pouring it into the glass. Alternatively, the bottle may be inverted prior to opening. Glass bottles are always used for bottle conditioned beers.
What ingredient is filtered out of most beers when it is packaged in bottles and cans?
Answer: yeast
Context and question: In Europe, Dutch is the majority language in the Netherlands (96%) and Belgium (59%) as well as a minority language in Germany and northern France's French Flanders, where it is in the ultimate stage of language death. Though Belgium as a whole is multilingual, the two regions into which the country is divided (Flanders, francophone Wallonia, bilingual Brussels and small 'facility' zones) are largely monolingual. The Netherlands and Belgium produce the vast majority of music, films, books and other media written or spoken in Dutch. Dutch is a monocentric language, with all speakers using the same standard form (authorized by the Dutch Language Union) based on a Dutch orthography employing the Latin alphabet when writing. In stark contrast to its written uniformity, Dutch lacks a prestige dialect and has a large dialectal continuum consisting of 28 main dialects, which can themselves be further divided into at least 600 distinguishable varieties.
What region in France is experiencing Dutch language death?
Answer:
French Flanders
