The phrase “recent global boom” describes something that began in the past and is
continuing into the present; hence, the present perfect tense “has led” is more
appropriate than the simple present tense “leads.” In addition, “such as” is preferred
to “like” when introducing examples.
(A) This choice is incorrect as it repeats the original sentence.
(B) The singular subject “boom” does not agree with the plural verb “have led.”
(C) The meaning of the sentence has changed because this choice states that the
number of “thieves” has increased rather than the number of “thefts.” In addition,
“such as” is preferred to “like” when introducing examples.
(D) CORRECT. This choice correctly uses the present perfect tense “has led” to
indicate that the boom began in the past and is continuing into the present, and also
to properly indicate that the boom started before the rise in theft. In addition, “such as”
is preferred to “like” when introducing examples.
(E) The present perfect tense “has led” is more appropriate than the present
progressive tense “is leading” because although the present progressive indicates an
action or state that is continuing, it does not properly indicate the relative time
sequence of the boom and the subsequent rise in the theft of metal objects.
