Context and question: In Texas, English is the state's de facto official language (though it lacks de jure status) and is used in government. However, the continual influx of Spanish-speaking immigrants increased the import of Spanish in Texas. Texas's counties bordering Mexico are mostly Hispanic, and consequently, Spanish is commonly spoken in the region. The Government of Texas, through Section 2054.116 of the Government Code, mandates that state agencies provide information on their websites in Spanish to assist residents who have limited English proficiency.
Are there exceptions to Texas official language?
Answer: , the continual influx of Spanish-speaking immigrants increased the import of Spanish in Texas.
Context and question: Proto-Slavic, the supposed ancestor language of all Slavic languages, is a descendant of common Proto-Indo-European, via a Balto-Slavic stage in which it developed numerous lexical and morphophonological isoglosses with the Baltic languages. In the framework of the Kurgan hypothesis, "the Indo-Europeans who remained after the migrations [from the steppe] became speakers of Balto-Slavic".
What did Proto-Indo-European form with Balto languages?
Answer: unanswerable
Context and question: 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.
