Which of the following statements is INCORRECT?

(9)The fiery June 24 collision between a tractor-trailer and an Amtrak train near Reno, which left six people dead and about 20 injured, showed stunning destructive power. But for Operation Lifesavers Inc. , an organization that works to prevent collisions on and around railroad tracks, the crash was a particularly tragic example of an all-too-common occurrence on the nation’s roadways: Since the Reno crash, there have been at least four other fatal truck-train collisions across the USA, plus at least two other non-fatal crashes, according to the company.
     (10)Now, the group is offering professional drivers a short, online, interactive safety course designed to help them make sound decisions at railroad crossings. Since June 9, about 15,000 truck drivers have taken the course, OL1 spokeswoman Marmie Edwards says. The group hopes to reach 100,000 drivers this year and eventually all professional truckers, who number about 3.5 million, according to the industry group American Trucking Associations. "It’s basically like a video game, but it’s a safety video game," Edwards says. In a simulated driving environment, drivers are exposed to worst-case scenarios that require quick thinking and critical decision-making, she says.
