In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Which of the following is NOT a goal of phorphor LED development: higher light output, optical losses, or higher operation temperatures?, Context: Among the challenges being faced to improve the efficiency of LED-based white light sources is the development of more efficient phosphors. As of 2010, the most efficient yellow phosphor is still the YAG phosphor, with less than 10% Stoke shift loss. Losses attributable to internal optical losses due to re-absorption in the LED chip and in the LED packaging itself account typically for another 10% to 30% of efficiency loss. Currently, in the area of phosphor LED development, much effort is being spent on optimizing these devices to higher light output and higher operation temperatures. For instance, the efficiency can be raised by adapting better package design or by using a more suitable type of phosphor. Conformal coating process is frequently used to address the issue of varying phosphor thickness.

What was the smallest denomination present in Warsaw?, Context: Throughout its existence, Warsaw has been a multi-cultural city. According to the 1901 census, out of 711,988 inhabitants 56.2% were Catholics, 35.7% Jews, 5% Greek orthodox Christians and 2.8% Protestants. Eight years later, in 1909, there were 281,754 Jews (36.9%), 18,189 Protestants (2.4%) and 2,818 Mariavites (0.4%). This led to construction of hundreds of places of religious worship in all parts of the town. Most of them were destroyed in the aftermath of the Warsaw Uprising of 1944. After the war, the new communist authorities of Poland discouraged church construction and only a small number were rebuilt.

What 2 streets end at Kips Bay Towers?, Context: 31st Street begins on the West Side at the West Side Yard, while 32nd Street, which includes a segment officially known as Korea Way between Fifth Avenue and Broadway in Manhattan's Koreatown, begins at the entrance to Penn Station and Madison Square Garden. On the East Side, both streets end at Second Avenue at Kips Bay Towers and NYU Medical Center which occupy the area between 30th and 34th Streets. The Catholic church of St. Francis of Assisi is situated at 135–139 West 31st Street. At 210 West is the Capuchin Monastery of St. John the Baptist, part of St. John the Baptist Church on 30th Street. At the corner of Broadway and West 31st Street is the Grand Hotel. The former Hotel Pierrepont was located at 43 West 32nd Street, The Continental NYC tower is at the corner of Sixth Avenue and 32nd Street. 29 East 32nd Street was the location of the first building owned by the Grolier Club between 1890 and 1917.
