Input: Article: The most precarious of these quake-lakes was the one located in the extremely difficult terrain at Mount Tangjia in Beichuan County, Sichuan, accessible only by foot or air; an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company was used to bring heavy earthmoving tractors to the affected location. This operation was coupled with the work done by PLAAF Mi-17 helicopters bringing in PLA engineering corps, explosive specialists and other personnel to join 1,200 soldiers who arrived on site by foot. Five tons of fuel to operate the machinery was airlifted to the site, where a sluice was constructed to allow the safe discharge of the bottlenecked water. Downstream, more than 200,000 people were evacuated from Mianyang by June 1 in anticipation of the dam bursting.

Now answer this question: Where was the most precarious quake lake located?

Output: Mount Tangjia in Beichuan County, Sichuan

Input: Article: Chopin's music is frequently played with rubato, "the practice in performance of disregarding strict time, 'robbing' some note-values for expressive effect". There are differing opinions as to how much, and what type, of rubato is appropriate for his works. Charles Rosen comments that "most of the written-out indications of rubato in Chopin are to be found in his mazurkas ... It is probable that Chopin used the older form of rubato so important to Mozart ... [where] the melody note in the right hand is delayed until after the note in the bass ... An allied form of this rubato is the arpeggiation of the chords thereby delaying the melody note; according to Chopin's pupil, Karol Mikuli, Chopin was firmly opposed to this practice."

Now answer this question: What does rubato mean?

Output: the practice in performance of disregarding strict time

A 1999 study estimated that DST increases the revenue of the European Union's leisure sector by about 3%.

Now answer this question: What year did Fortune magazine make predictions about the increased revenue an extended daylight savings would provide?

Output:
