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

Ex Input:
What gave these hunters their food supply?, Context: Evidence suggests big-game hunter gatherers crossed the Bering Strait from Asia (Eurasia) into North America over a land bridge (Beringia), that existed between 47,000–14,000 years ago. Around 18,500-15,500 years ago, these hunter-gatherers are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America.

Ex Output:
big-game


Ex Input:
what type of string is mentioned third to last?, Context: Samuel Adelstein described the Lombardi mandolin in 1893 as wider and shorter than the Neapolitan mandolin, with a shallower back and a shorter and wider neck, with six single strings to the regular mandolin's set of 4. The Lombardi was tuned C, D, A, E, B, G. The strings were fastened to the bridge like a guitar's. There were 20 frets, covering three octaves, with an additional 5 notes. When Adelstein wrote, there were no nylon strings, and the gut and single strings "do not vibrate so clearly and sweetly as the double steel string of the Neapolitan."

Ex Output:
gut


Ex Input:
Which of the following is not a surname: McDonald, Tower or Rocka?, Context: This vibrant and culturally diverse area of retail businesses and residences experienced a renewal after a significant decline in the late 1960s and 1970s.[citation needed] After decades of neglect and suburban flight, the neighborhood revival followed the re-opening of the Tower Theatre in the late 1970s, which at that time showed second and third run movies, along with classic films. Roger Rocka's Dinner Theater & Good Company Players also opened nearby in 1978,[citation needed] at Olive and Wishon Avenues. Fresno native Audra McDonald performed in the leading roles of Evita and The Wiz at the theater while she was a high school student. McDonald subsequently became a leading performer on Broadway in New York City and a Tony award winning actress. Also in the Tower District is Good Company Players' 2nd Space Theatre.

Ex Output:
Tower
