-
D.
25 to 30 percent Correct
The answer is "25 to 30 percent"
The manual attributes 25 to 30 percent of police-reported crashes to distraction and inattention. Pick A and you are leaning on a rough 'one in five' rule of thumb that gets applied to various crash-cause statistics.
The traps in the wrong answers
A. 15 to 20 percent
The manual's number is higher than one in five. This answer falls back on a rough 'one in five' rule of thumb learners apply to various crash-cause statistics.
B. 45 to 50 percent
The manual does not put distraction at nearly half of all reported crashes. This answer overstates the figure by mixing it up with 'about half' language commonly attached to fatal-crash headlines.
C. 5 to 10 percent
This range understates the manual's figure for distraction-related crashes. This answer guesses low on the assumption that most crashes trace to speed, alcohol, or weather rather than driver inattention.
