Which statement, if true, would most strongly support Wade's argument?

In medieval England, singers and minstrels made livings as traveling performers, but the pieces they performed have been a mystery, thought to be lost or never committed to paper at all. Recently, however, James Wade has argued that a manuscript collection compiled in the fifteenth century by Richard Heege contains three pieces likely copied from a repertoire book belonging to a minstrel working in the area around Heege's home. Wade cites features of the texts indicative of live performance, such as chastising the audience, extensive use of simple structures (allowing for easy memorization), and requests for tips (payment) from listeners.

Heege's collection contains the earliest examples of the three pieces in question, but each of those pieces occurs in other manuscript collections compiled after Heege's.

The three pieces in question contain references that presume that the audience is familiar with Brackenwet and other small villages near where Heege lived.

Features like simple structures also occur in other texts from the period that were widely read but are not known to have been performed for live audiences.

Traveling minstrels are thought to have performed mainly for elite audiences, and other parts of Heege's collection reflect his interest in works with popular appeal.
