Which аnswer prоvides аn аpprоpriate paraphrase оf the following passage? Most of us think that S.U.V.s are much safer than sports cars. If you asked the young parents of America whether they would rather strap their infant child in the back seat of the TrailBlazer [a Chevrolet SUV] or the passenger seat of the Boxster [a Porsche sports car], they would choose the TrailBlazer. We feel that way because in the TrailBlazer our chances of surviving a collision with a hypothetical tractor‑trailer in the other lane are greater than they are in the Porsche. What we forget, though, is that in the TrailBlazer you’re also much more likely to hit the tractor‑trailer because you can’t get out of the way in time. In the parlance of the automobile world, the TrailBlazer is better at “passive safety.” The Boxster is better when it comes to “active safety,” which is every bit as important. The passage, written by Malcolm Gladwell, is from an article titled “Big and Bad” that appears on pages 31-35 of the January 2004 edition of the New Yorker.
