context: Building construction is the process of adding structure to real property or construction of buildings. The majority of building construction jobs are small renovations, such as addition of a room, or renovation of a bathroom. Often, the owner of the property acts as laborer, paymaster, and design team for the entire project. Although building construction projects typically include various common elements, such as design, financial, estimating and legal considerations, many projects of varying sizes reach undesirable end results, such as structural collapse, cost overruns, and/or litigation. For this reason, those with experience in the field make detailed plans and maintain careful oversight during the project to ensure a positive outcome.

proper question: What is one work by Neumes?
disfluent question: What is one work by Messiaen oh sorry, by Neumes?
context: Prime numbers have influenced many artists and writers. The French composer Olivier Messiaen used prime numbers to create ametrical music through natural phenomena. In works such as La Nativite du Seigneur (1935) and Quatre etudes de rythme (194950), he simultaneously employs motifs with lengths given by different prime numbers to create unpredictable rhythms: the primes 41, 43, 47 and 53 appear in the third etude, Neumes rythmiques. According to Messiaen this way of composing was inspired by the movements of nature, movements of free and unequal durations.

proper question: The two former deputies of Parliament are whom?
disfluent question: Who is elected using an open ballot or wait who are the two former deputies of Parliament?
context: After each election to the Scottish Parliament, at the beginning of each parliamentary session, Parliament elects one MSP to serve as Presiding Officer, the equivalent of the speaker (currently Tricia Marwick), and two MSPs to serve as deputies (currently Elaine Smith and John Scott). The Presiding Officer and deputies are elected by a secret ballot of the 129 MSPs, which is the only secret ballot conducted in the Scottish Parliament. Principally, the role of the Presiding Officer is to chair chamber proceedings and the Scottish Parliamentary Corporate Body. When chairing meetings of the Parliament, the Presiding Officer and his/her deputies must be politically impartial. During debates, the Presiding Officer (or the deputy) is assisted by the parliamentary clerks, who give advice on how to interpret the standing orders that govern the proceedings of meetings. A vote clerk sits in front of the Presiding Officer and operates the electronic voting equipment and chamber clocks.
