In addition to advocating for South America’s independence in two political treatises, the Cartagena Manifesto and the Letter
from Jamaica, Simón Bolívar personally led armies against the Spanish, liberating three South American territories—New
Granada (present-day Colombia and Panama), Venezuela, and Quito (present-day ______ from colonial rule.
Ecuador,)
Ecuador)
Ecuador),
Ecuador)—
Choice D is the best answer. The convention being tested is the punctuation of a supplementary element within a sentence.
The dash after “Ecuador” and the closing parenthesis pairs with the dash after “territories” to separate the supplementary
element (“New…Ecuador”) from the rest of the sentence. The supplementary element speciﬁes the three South American
territories that Simón Bolívar liberated, and the pair of dashes indicates that this element could be removed without affecting
the grammatical coherence of the sentence.
Choice A is incorrect because it fails to use appropriate punctuation to separate the supplementary element from the rest of
the sentence. Furthermore, punctuation isn’t needed between “Ecuador” and the closing parenthesis. Choice B is incorrect
because it fails to use appropriate punctuation to separate the supplementary element from the rest of the sentence. Choice
C is incorrect because a comma can’t be paired with a dash to separate the supplementary element from the rest of the
sentence.
