Problem:Buck and Annie had been praying for her younger siblings for quite a while, so for the two children to come live with the couple was ``a foregone conclusion.`` There was some conflict as the two families tried to merge. Soon after Nelly and Matthew came to live with the Herrings, the three siblings began singing together. Annie usually sang lead, Matthew harmonized, and Nelly's rich alto voice found the missing notes between the two. Although _she_ rarely sang lead, Greisen's harmonies tended to be more complicated than her brother's. <sep>, Pronoun: she <sep>, A: Nelly <sep>, B: Greisen
Solution:
B
