Question: Who constructed the building that has been used as a health centre for the community, a school teaching kung fu, and a museum? Passage:From its southern end, Stone Nullah Lane begins at its junction with Lung On Street. This is where the Wan Chai Pak Tai Temple is located. Made from grey-coloured brick and granite, it was constructed in 1863, although the statue of Pak Tai inside dates even further back to 1604. The temple is the oldest in the district, and reportedly the largest on Hong Kong Island. The next landmark on the route is the headquarters of St. James' Settlement. Situated at 85 Stone Nullah Lane, the charitable organisation was established here in 1949 with the goal of helping impoverished children living in squats around the neighbourhood, and now extends its services to needy people across the city. The current structure towers 12-storeys above the lane. Before the street turns onto Queen's Road East and ends, it passes the Blue House, a Grade I historic building. The buildingwhose Spanish balconies made from cast-iron have elicited comparisons to ones in New Orleanswas built in the 1920s and was originally utilised as a health centre for the community, a school teaching kung fu from the 1950s to 1960s, and now houses a museum.

Question: Who was older when Heitler obtained his doctorate, Arnold Sommerfeld or Karl Herzfeld? Passage:In 1922, Heitler began his study of physics at the Karlsruhe Technische Hochschule, in 1923 at the Humboldt University of Berlin, and in 1924 at the Ludwig Maximilian University of Munich (LMU), where he studied under both Arnold Sommerfeld and Karl Herzfeld. The latter was his thesis advisor when he obtained his doctorate in 1926; Herzfeld taught courses in theoretical physics and one in physical chemistry, and in Sommerfeld's absence often took over his classes. From 1926 to 1927, he was a Rockefeller Foundation Fellow for postgraduate research with Niels Bohr at the Institute for Theoretical Physics at the University of Copenhagen and with Erwin Schrodinger at the University of Zurich. He then became an assistant to Max Born at the Institute for Theoretical Physics at the University of Gottingen. Heitler completed his Habilitation, under Born, in 1929, and then remained as a Privatdozent until 1933. In that year, he was let go by the university because he was Jewish.

Question: How many tracks other than Kitty Kat were included on the album that it was on? Passage:"Kitty Kat" received generally favorable reviews from critics. Eb Haynes of AllHipHop described "Kitty Kat" as a seductive track. Norman Mayers of Prefix Magazine wrote that B'Day is packed with standouts such as "the Rich Harrison-produced 'Freakum Dress' and the Neptunes-helmed 'Kitty Kat'." Picking out "Kitty Kat" as one of the four top tracks of the album, Spence D of IGN Music added that the song slows things down, allowing for Knowles' "crystal clear vocals to take some down time and relinquish up a dreamy, creamy sound that is playfully sensuous." Andy Kellman of Allmusic described "Kitty Kat" as "a deceptively sweet, rainbow-colored track" where purrs - that are sound made by all species of felids and are a part of cat communication - are more like "claws-out dismissals." Jon Pareles of The New York Times called the song a "cooing [and] sighing" one. Sal Cinquemani of Slant Magazine noted that "Kitty Kat" was "the only mid-tempo break" until the very end of the album. Darryl Sterdan, writing for the Canadian website Jam!, said that the song is just about what you think. Thomas Inskeep of Stylus Magazine commented that "Kitty Kat" seems to be an obvious tracks produced by The Neptunes. He went on complimenting "the squishy R&B keyboard which works well with the song's 'I'm not feelin[g] it' vibe." A writer of the Seattle Post-Intelligencer commented, "Beyonce is better at being sexy than sarcastic, and 'Kitty Kat' doesn't make any bones about what her absentee lover is missing." Michael Roberts of New Times Broward-Palm Beach commented that Knowles "purrs at lower speed" in the song.
