This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Input: Consider Input: 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.

Output: What aids in predicting changes of physical traits?


Input: Consider Input: The University of the Republic is the country's largest and most important university, with a student body of 81,774, according to the census of 2007. It was founded on 18 July 1849 in Montevideo, where most of its buildings and facilities are still located. Its current Rector is Dr. Rodrigo Arocena. The university houses 14 faculties (departments) and various institutes and schools. Many eminent Uruguayans have graduated from this university, including Carlos Vaz Ferreira, José Luis Massera, Gabriel Paternain, Mario Wschebor, Roman Fresnedo Siri, Carlos Ott and Eladio Dieste

Output: What is the country's largest university? 


Input: Consider Input: Over time, Roman architecture was modified as their urban requirements changed, and the civil engineering and building construction technology became developed and refined. The Roman concrete has remained a riddle, and even after more than 2,000 years some Roman structures still stand magnificently. The architectural style of the capital city was emulated by other urban centers under Roman control and influence. Roman cities were well planned, efficiently managed and neatly maintained.[citation needed]


Output: What was a primary cause of the modification of Roman architectural elements?
