[Q]: proper question: The Paris Palace had been an exceptional example of what type of architecture? 
 disfluent question: The Warsaw Philharmonic edifice, oh, I mean, the Paris Palace had been an exceptional example of what type of architecture? 
 context: Exceptional examples of the bourgeois architecture of the later periods were not restored by the communist authorities after the war (like mentioned Kronenberg Palace and Insurance Company Rosja building) or they were rebuilt in socialist realism style (like Warsaw Philharmony edifice originally inspired by Palais Garnier in Paris). Despite that the Warsaw University of Technology building (1899–1902) is the most interesting of the late 19th-century architecture. Some 19th-century buildings in the Praga district (the Vistula’s right bank) have been restored although many have been poorly maintained. Warsaw’s municipal government authorities have decided to rebuild the Saxon Palace and the Brühl Palace, the most distinctive buildings in prewar Warsaw.

[Q]: proper question: What happens to some sheaths on cydippids to change their size? 
 disfluent question: What  is the mouth of a pleurobrachia kept in no forget that and tell me what happens to some sheaths on cydippids to change their size? 
 context: Cydippid ctenophores have bodies that are more or less rounded, sometimes nearly spherical and other times more cylindrical or egg-shaped; the common coastal sea gooseberry, Pleurobrachia, sometimes has an egg-shaped body with the mouth at the narrow end, although some individuals are more uniformly round. From opposite sides of the body extends a pair of long, slender tentacles, each housed in a sheath into which it can be withdrawn. Some species of cydippids have bodies that are flattened to various extents, so that they are wider in the plane of the tentacles.

[Q]: proper question: What is another word for the study of past and current life? 
 disfluent question: What is another method no word for the study of past and current life? 
 context: Geologists use a number of field, laboratory, and numerical modeling methods to decipher Earth history and understand the processes that occur on and inside the Earth. In typical geological investigations, geologists use primary information related to petrology (the study of rocks), stratigraphy (the study of sedimentary layers), and structural geology (the study of positions of rock units and their deformation). In many cases, geologists also study modern soils, rivers, landscapes, and glaciers; investigate past and current life and biogeochemical pathways, and use geophysical methods to investigate the subsurface.
