The advanced technology of ski boots and bindings has brought a dramatic drop in the incidence of injuries that occur on the slopes of ski resorts: from 9 injuries per 1,000 skiers in 1950 to 3 in 1980. As a result, the remainder of ski-related injuries, which includes all injuries occurring on the premises of a ski resort but not on the slopes, rose from 10 percent of all ski-related injuries in 1950 to 25 percent in 1980. The incidence of these injuries, including accidents such as falling down steps, increases with the amount of alcohol consumed per skier.
Which one of the following conflicts with information in the passage?
(A) The number of ski injuries that occurred on the slopes was greater in 1980 than in 1950.
(B) A skier was less likely to be injured on the slopes in 1950 than in 1980.
(C) The reporting of ski injuries became more accurate between 1950 and 1980.
(D) The total number of skiers dropped between 1950 and 1980.
(E) Some ski-related injuries occurred in 1980 to people who were not skiing.
Answer is B, Choice A is very tempting. The only error in A is that it states the 'number of injuries' which is the total number, while the information we have in hand is just the ratio against 1000 skiers.
