Input: Read this: Likewise, group theory helps predict the changes in physical properties that occur when a material undergoes a phase transition, for example, from a cubic to a tetrahedral crystalline form. An example is ferroelectric materials, where the change from a paraelectric to a ferroelectric state occurs at the Curie temperature and is related to a change from the high-symmetry paraelectric state to the lower symmetry ferroelectic state, accompanied by a so-called soft phonon mode, a vibrational lattice mode that goes to zero frequency at the transition.
Question: What term describes the vibrational lattice mode that turns to 0 frequency at the change?

Output: soft phonon mode

Input: Read this: There are also three Deputy Chiefs of the Defence Staff with particular remits, Deputy Chief of the Defence Staff (Capability), Deputy CDS (Personnel and Training) and Deputy CDS (Operations). The Surgeon General, represents the Defence Medical Services on the Defence Staff, and is the clinical head of that service.
Question: How many Deputy Chiefs of the Defence Staff are there?

Output: three

Input: Read this: The city also has several major surface arteries. U.S. Route 1 (Columbus Avenue, Union Avenue, Water Street, Forbes Avenue) runs in an east-west direction south of downtown serving Union Station and leading out of the city to Milford, West Haven, East Haven and Branford. The main road from downtown heading northwest is Whalley Avenue (partly signed as Route 10 and Route 63) leading to Westville and Woodbridge. Heading north towards Hamden, there are two major thoroughfares, Dixwell Avenue and Whitney Avenue. To the northeast are Middletown Avenue (Route 17), which leads to the Montowese section of North Haven, and Foxon Boulevard (Route 80), which leads to the Foxon section of East Haven and to the town of North Branford. To the west is Route 34, which leads to the city of Derby. Other major intracity arteries are Ella Grasso Boulevard (Route 10) west of downtown, and College Street, Temple Street, Church Street, Elm Street, and Grove Street in the downtown area.
Question: What road leading northwest from downtown New Haven comprises both Route 10 and Route 63 at various points?

Output: Whalley Avenue

Input: Read this: This can give rise to the situation in which two dialects (defined according to this paradigm) with a somewhat distant genetic relationship are mutually more readily comprehensible than more closely related dialects. In one opinion, this pattern is clearly present among the modern Romance languages, with Italian and Spanish having a high degree of mutual comprehensibility, which neither language shares with French, despite some claiming that both languages are genetically closer to French than to each other:[citation needed] In fact, French-Italian and French-Spanish relative mutual incomprehensibility is due to French having undergone more rapid and more pervasive phonological change than have Spanish and Italian, not to real or imagined distance in genetic relationship. In fact, Italian and French share many more root words in common that do not even appear in Spanish.
Question: Which two languages share numerous root words that aren't even in the Romance language?

Output:
unanswerable
