Input: Read this: Several twentieth-century presidents have attempted to greatly expand the power of the presidency. Theodore Roosevelt, for instance, claimed that the president was permitted to do whatever was not explicitly prohibited by the lawin direct contrast to his immediate successor, William Howard Taft. Franklin Delano Roosevelt held considerable power during the Great Depression. Congress had granted Franklin Roosevelt sweeping authority; in Panama Refining v. Ryan, the Court for the first time struck down a Congressional delegation of power as violative of the doctrine of separation of powers. The aforementioned Schechter Poultry Corp. v. United States, another separation of powers case, was also decided during Franklin Roosevelt's presidency. In response to many unfavorable Supreme Court decisions, Roosevelt introduced a "Court Packing" plan, under which more seats would be added to the Supreme Court for the president to fill. Such a plan (which was defeated in Congress) would have seriously undermined the judiciary's independence and power.

Input: Read this: Beginning with the Paris Exposition of 1878, the instrument's popularity rebounded. The Exposition was one of many stops for a popular new performing group the Estudiantes Espanoles (Spanish Students). They danced and played guitars, violins and the bandurria, which became confused with the mandolin. Along with the energy and awareness created by the day's hit sensation, a wave of Italian mandolinists travelled Europe in the 1880s and 1890s and in the United States by the mid-1880s, playing and teaching their instrument. The instrument's popularity continued to increase during the 1890s and mandolin popularity was at its height in "early years of the 20th century." Thousands were taking up the instrument as a pastime, and it became an instrument of society, taken up by young men and women. Mandolin orchestras were formed worldwide, incorporating not only the mandolin family of instruments, but also guitars, double basses and zithers.
Question: What instrument was the mandolin never confused with during the 1880's?

Input: Read this: Founded by Dantidurga around 753, the Rashtrakuta Empire ruled from its capital at Manyakheta for almost two centuries. At its peak, the Rashtrakutas ruled from the Ganges River and Yamuna River doab in the north to Cape Comorin in the south, a fruitful time of political expansion, architectural achievements and famous literary contributions.[citation needed] The early kings of this dynasty were Hindu but the later kings were strongly influenced by Jainism. Govinda III and Amoghavarsha were the most famous of the long line of able administrators produced by the dynasty. Amoghavarsha, who ruled for 64 years, was also an author and wrote Kavirajamarga, the earliest known Kannada work on poetics. Architecture reached a milestone in the Dravidian style, the finest example of which is seen in the Kailasanath Temple at Ellora. Other important contributions are the sculptures of Elephanta Caves in modern Maharashtra as well as the Kashivishvanatha temple and the Jain Narayana temple at Pattadakal in modern Karnataka, all of which are UNESCO World Heritage Sites. The Arab traveler Suleiman described the Rashtrakuta Empire as one of the four great Empires of the world. The Rashtrakuta period marked the beginning of the golden age of southern Indian mathematics. The great south Indian mathematician Mahavira (mathematician) lived in the Rashtrakuta Empire and his text had a huge impact on the medieval south Indian mathematicians who lived after him. The Rashtrakuta rulers also patronised men of letters, who wrote in a variety of languages from Sanskrit to the Apabhramsas.
