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.

Example 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.
Example Output: What aids in predicting changes of physical traits?

Example Input: While the Warsaw Pact was established as a balance of power or counterweight to NATO, there was no direct confrontation between them. Instead, the conflict was fought on an ideological basis. Both NATO and the Warsaw Pact led to the expansion of military forces and their integration into the respective blocs. The Warsaw Pact's largest military engagement was Warsaw Pact invasion of Czechoslovakia (with the participation of all Pact nations except Romania and Albania). The Pact failed to function when the Revolutions of 1989 spread through Eastern Europe, beginning with the Solidarity movement in Poland and its success in June 1989.
Example Output: Which organization was in direct competition with the Warsaw Pact?

Example Input: There are two broad categories of public funding, direct, which entails a monetary transfer to a party, and indirect, which includes broadcasting time on state media, use of the mail service or supplies. According to the Comparative Data from the ACE Electoral Knowledge Network, out of a sample of over 180 nations, 25% of nations provide no direct or indirect public funding, 58% provide direct public funding and 60% of nations provide indirect public funding. Some countries provide both direct and indirect public funding to political parties. Funding may be equal for all parties or depend on the results of previous elections or the number of candidates participating in an election. Frequently parties rely on a mix of private and public funding and are required to disclose their finances to the Election management body.
Example Output:
What are the two categories of public funding?
