Context and question: Special guest referees may be used from time to time; by virtue of their celebrity status, they are often scripted to dispense with the appearance of neutrality and use their influence to unfairly influence the outcome of the match for added dramatic impact. Face special referees will often fight back against hostile heel wrestlers, particularly if the special referee is either a wrestler themselves or a famous martial artist (such as Tito Ortiz in the main event at TNA's THard Justice in 2005). They also have the power to eject from ringside any of the heel wrestler's entourage/stable, who may otherwise interfere with the match.
What are famous referees directed to do?
Answer: often scripted to dispense with the appearance of neutrality and use their influence to unfairly influence the outcome of the match for added dramatic impact. F
Context and question: The most familiar, and historically the oldest, types of glass are "silicate glasses" based on the chemical compound silica (silicon dioxide, or quartz), the primary constituent of sand. The term glass, in popular usage, is often used to refer only to this type of material, which is familiar from use as window glass and in glass bottles. Of the many silica-based glasses that exist, ordinary glazing and container glass is formed from a specific type called soda-lime glass, composed of approximately 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives. A very clear and durable quartz glass can be made from pure silica, but the high melting point and very narrow glass transition of quartz make glassblowing and hot working difficult. In glasses like soda lime, the compounds added to quartz are used to lower the melting temperature and improve workability, at a cost in the toughness, thermal stability, and optical transmittance.
Which kinds of glass existed the furthest in the past?
Answer: silicate glasses
Context and question: In July 1963 the Mongolian People's Republic asked to join the Warsaw Pact under Article 9 of the treaty. For this purpose a special protocol should have been taken since the text of the treaty applied only to Europe. Due to the emerging Sino-Soviet split, Mongolia remained on observer status. Soviet stationing troops were agreed to stay in Mongolia from 1966.
