OFFICIAL EXPLANATIONQuote:
Although the port city of Bristol was once home to a thriving maritime trade,
its economy has in more recent years depended on the creative media, electronics, and aerospace industries.
A) its economy has in more recent years depended
B)
their economy has in more recent years depended
C) its economy
had depended in more recent years
D) its economy
having in more recent years
dependedE)
their economy has been dependent in more recent years
• Split #1: Pronoun AgreementAny city, including Bristol, is singular. (A city is a collective noun.)
The possessive pronoun should be singular
its economy, not plural
their economy.
Options B and E incorrectly use
theirELIMINATE B AND E
• Split #2: verb tenseOption D does not contain a working verb (a verb that could be in a main sentence).
→ The verbal
having creates a fragment.
Wrong: He having a dog in his backyard. [fragment!]
Correct: He has a dog in his backyard.
The verb
has can be very tricky for non-native speakers, though not in this question.
Just remember that
(1) HAS/HAVE can mean
owns, possesses, or
experiences, AND
(2) HAS/HAVE can also be helping verbs.
Option C incorrectly uses
had depended→
had depended is in past perfect tense, which should be used for the
earlier of two prior events
→ but the verb in question is referring to an action that occurred second in time (economic dependence on technology came
after dependence on maritime trade)
Timeline: ...[a long time ago] maritime trade grounds the economy → → → [now] creative media and other technology grounds the economy
→ The words
in more recent years signal that Bristol's economic dependence on media and technology is
recent—not, as past perfect conveys, "the past of the past."
ELIMINATE C AND D
By process of elimination, the correct answer is A.
→ Correct pronoun: Bristol's economy = its economy
→ Correct verb:
has depended correctly refers to a recent occurrence and uses
present perfect, which describes something that began in the past and continues into the present or whose effects continue into the present
--
present perfect is often described as a bridge that connects past and present
present perfect is constructed this way: HAS/HAVE + past participle (verbED)
