Which choice completes the text so that it conforms to the conventions of Standard English?

Question

Ethnomusicologist Sofía Delgado's archive documents three distinct Afro-Latin percussion traditions: the bomba drumming of Loíza, Puerto Rico; the tamborito of Panama's Azuero Peninsula ______ marimba ensembles of Colombia's Pacific coast.

Accepted Answer

A. ; and the. Because the first item in the series ("the bomba drumming of Loíza, Puerto Rico") already contains an internal comma, the items must be separated by semicolons; the writer has already used a semicolon after "Puerto Rico," so the final item must likewise be introduced with a semicolon plus the coordinating conjunction: "; and the marimba ensembles." (B) switches to a comma partway through a semicolon series, producing inconsistent punctuation and blurring where the second item ends and the third begins — the error of treating this as an ordinary comma series. (C) omits punctuation altogether, so "the tamborito of Panama's Azuero Peninsula and the marimba ensembles of Colombia's Pacific coast" reads as a single compound item, leaving only two items where three are announced. (D) substitutes a dash for the required semicolon, breaking the parallel punctuation of the series and wrongly signaling a break or amplification rather than a list boundary.

Answer

B. , and the — The series already uses a semicolon after "Puerto Rico" because the first item contains its own comma, so switching to a comma here makes the punctuation inconsistent and blurs the item boundaries.

Answer

C.  and the — With no punctuation, "the tamborito ... and the marimba ensembles ..." reads as one combined item, leaving only two traditions when three were announced.

Answer

D. —and the — A dash signals a break or amplification, not a list boundary; the series needs the same semicolon used after "Puerto Rico" to stay parallel.
