Problem: Question: "What group does whole recordings using vocal instrumentation only?" Context: "In addition to singing words, some a cappella singers also emulate instrumentation by reproducing instrumental sounds with their vocal cords and mouth. One of the earliest 20th century practitioners of this method were The Mills Brothers whose early recordings of the 1930s clearly stated on the label that all instrumentation was done vocally. More recently, "Twilight Zone" by 2 Unlimited was sung a cappella to the instrumentation on the comedy television series Tompkins Square. Another famous example of emulating instrumentation instead of singing the words is the theme song for The New Addams Family series on Fox Family Channel (now ABC Family). Groups such as Vocal Sampling and Undivided emulate Latin rhythms a cappella. In the 1960s, the Swingle Singers used their voices to emulate musical instruments to Baroque and Classical music. Vocal artist Bobby McFerrin is famous for his instrumental emulation. A cappella group Naturally Seven recreates entire songs using vocal tones for every instrument." Answer:

A: The Mills Brothers

Problem: Question: "An Imperial Army officer who was disciplined, highly motivated, and exceptionally trained, likely used to be able to do what but no longer was allowed to?" Context: "Emperor Meiji abolished the samurai's right to be the only armed force in favor of a more modern, western-style, conscripted army in 1873. Samurai became Shizoku () who retained some of their salaries, but the right to wear a katana in public was eventually abolished along with the right to execute commoners who paid them disrespect. The samurai finally came to an end after hundreds of years of enjoyment of their status, their powers, and their ability to shape the government of Japan. However, the rule of the state by the military class was not yet over. In defining how a modern Japan should be, members of the Meiji government decided to follow the footsteps of the United Kingdom and Germany, basing the country on the concept of noblesse oblige. Samurai were not a political force under the new order. With the Meiji reforms in the late 19th century, the samurai class was abolished, and a western-style national army was established. The Imperial Japanese Armies were conscripted, but many samurai volunteered as soldiers, and many advanced to be trained as officers. Much of the Imperial Army officer class was of samurai origin, and were highly motivated, disciplined, and exceptionally trained." Answer:

A:
the right to wear a katana in public was eventually abolished along with the right to execute commoners who paid them disrespect
