Problem: A cappella:

A cappella music was originally used in religious music, especially church music as well as anasheed and zemirot. Gregorian chant is an example of a cappella singing, as is the majority of secular vocal music from the Renaissance. The madrigal, up until its development in the early Baroque into an instrumentally-accompanied form, is also usually in a cappella form. Jewish and Christian music were originally a cappella,[citation needed] and this practice has continued in both of these religions as well as in Islam.

The madrigal became what type of form that prevented it from being accompanied with A cappella?

A: instrumentally-accompanied

Problem: But by the 1940s, many of Boas' anthropologist contemporaries were active in the allied war effort against the "Axis" (Nazi Germany, Fascist Italy, and Imperial Japan).

Price's work on American anthropology during the Cold War provides detailed accounts of the pursuit and dismissal of several anthropologists from their jobs for communist sympathies.
