The activism of state citizens, who have demanded safer road conditions as well as stiffer penalties for intoxicated drivers, have led to a significant decrease in the number of traffic accidents.
A. have led to a significant decrease in the number
B. have led to significant decreases in the amount
C. has led to a significant decrease in the number
D. has been significant in the decrease in the number
E. has significantly decreased the amount
Split #1: activism, singular, needs the singular verb has ledEliminate options A and B because both incorrectly use
have led.Split #2: amount versus numberamount is used for uncountable nouns, this way:
-- a significant amount of water evaporated
-- the amount of pollution decreased because of strict carpooling laws
number is used for countable nouns, this way
-- the number of traffic accidents decreased
Options B and E incorrectly use
amount of traffic accidents.
Number of traffic accidents is correct.
Eliminate E (B already eliminated)
Split #3 : Meaning and causality
(C) "X [b]has led to a decrease in the number of Y" is clear.
X caused the decrease.
(D) "X
has been significant in the decrease in the number of Y" is not as clear as (C).
-- What does "has been significant" mean?
-- Was
activism literally was in the middle of [was significant in] the decrease
-- "Has been significant" does not make a straightforward causal connection between
activism and the
decrease.-- The verb phrase "has been (significant) in" is not as strong or logically clear as "has led to."
-- Compare to the clear and direct logic in (C), which says
X has led to Y.To describe something as
being significant in" does not establish direct causality, and certainly does not express causality as well as Option (C)
The correct answer is C
