disfluent question: Which style was the Warsaw actually I mean the Paris Philharmony edifice built in?
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 (18991902) 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 Bruhl Palace, the most distinctive buildings in prewar Warsaw.

context: The Computer Science Network (CSNET) was a computer network funded by the U.S. National Science Foundation (NSF) that began operation in 1981. Its purpose was to extend networking benefits, for computer science departments at academic and research institutions that could not be directly connected to ARPANET, due to funding or authorization limitations. It played a significant role in spreading awareness of, and access to, national networking and was a major milestone on the path to development of the global Internet.

[Q]: proper question: What percentage of hours of light are there in December?
disfluent question: What percentage of hours of light are there in July errm rather December?
context: Fresno is marked by a semi-arid climate (Koppen BSh), with mild, moist winters and hot and dry summers, thus displaying Mediterranean characteristics. December and January are the coldest months, and average around 46.5 F (8.1 C), and there are 14 nights with freezing lows annually, with the coldest night of the year typically bottoming out below 30 F (1.1 C). July is the warmest month, averaging 83.0 F (28.3 C); normally, there are 32 days of 100 F (37.8 C)+ highs and 106 days of 90 F (32.2 C)+ highs, and in July and August, there are only three or four days where the high does not reach 90 F (32.2 C). Summers provide considerable sunshine, with July peaking at 97 percent of the total possible sunlight hours; conversely, January is the lowest with only 46 percent of the daylight time in sunlight because of thick tule fog. However, the year averages 81% of possible sunshine, for a total of 3550 hours. Average annual precipitation is around 11.5 inches (292.1 mm), which, by definition, would classify the area as a semidesert. Most of the wind rose direction occurrences derive from the northwest, as winds are driven downward along the axis of the California Central Valley; in December, January and February there is an increased presence of southeastern wind directions in the wind rose statistics. Fresno meteorology was selected in a national U.S. Environmental Protection Agency study for analysis of equilibrium temperature for use of ten-year meteorological data to represent a warm, dry western United States locale.
