Extract the answer to the question from the following context. Question: what is the second type of instrument mentioned? Context: The mandolin orchestras never completely went away, however. In fact, along with all the other musical forms the mandolin is involved with, the mandolin ensemble (groups usually arranged like the string section of a modern symphony orchestra, with first mandolins, second mandolins, mandolas, mandocellos, mando-basses, and guitars, and sometimes supplemented by other instruments) continues to grow in popularity. Since the mid-nineties, several public-school mandolin-based guitar programs have blossomed around the country, including Fretworks Mandolin and Guitar Orchestra, the first of its kind. The national organization, Classical Mandolin Society of America, founded by Norman Levine, represents these groups. Prominent modern mandolinists and composers for mandolin in the classical music tradition include Samuel Firstman, Howard Fry, Rudy Cipolla, Dave Apollon, Neil Gladd, Evan Marshall, Marilynn Mair and Mark Davis (the Mair-Davis Duo), Brian Israel, David Evans, Emanuil Shynkman, Radim Zenkl, David Del Tredici and Ernst Krenek.

Extract the answer to the question from the following context. Question: What are the names of two members of the mandolin family of instruments? Context: Instruments were marketed by teacher-dealers, much as the title character in the popular musical The Music Man. Often, these teacher-dealers conducted mandolin orchestras: groups of 4-50 musicians who played various mandolin family instruments. However, alongside the teacher-dealers were serious musicians, working to create a spot for the instrument in classical music, ragtime and jazz. Like the teacher-dealers, they traveled the U.S., recording records, giving performances and teaching individuals and mandolin orchestras. Samuel Siegel played mandolin in Vaudeville and became one of America's preeminent mandolinists. Seth Weeks was an African American who not only taught and performed in the United States, but also in Europe, where he recorded records. Another pioneering African American musician and director who made his start with a mandolin orchestra was composer James Reese Europe. W. Eugene Page toured the country with a group, and was well known for his mandolin and mandola performances. Other names include Valentine Abt, Samuel Adelstein, William Place, Jr., and Aubrey Stauffer.
Ans: mandolin and mandola
