IMO E

Its "A"

An E

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.
24. Which one of the following can be properly inferred from the passage?

(A) As the number of ski injuries that occur on the slopes decreases, the number of injuries that occur on the premises of ski resorts increases.

(B) The amount of alcohol consumed per skier increased between 1950 and 1980.

(C) The technology of ski boots and bindings affects the incidence of each type of ski-related injury.

(D) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline.

(E) Injuries that occurred on the slopes of ski resorts made up a smaller percentage of ski-related injuries in 1980 than in 1950.

My answer: E

Situation:
1. Injuries on slopes decreased due to technological improvements
2. As a result proportion of other ski-related injuries decreased.
3. Other injuries increases with alcohol consumed.

A. There is no correlation between the numbers.
B. Can't tell, since we're not given total number of ski-related injuries. the percentage increase could have been due solely to proportionate decrease on the slopes.
C. people don't wear ski boots only everywhere they go in the resort.
D. same as C.
E. this is exactly what is stated in the first sentence.

Yes, it's E, obviously

24. Which one of the following can be properly inferred from the passage?

(A) As the number of ski injuries that occur on the slopes decreases, the number of injuries that occur on the premises of ski resorts increases. -->no info support this

(B) The amount of alcohol consumed per skier increased between 1950 and 1980. -->no info support this

(C) The technology of ski boots and bindings affects the incidence of each type of ski-related injury. -->no, it just affect injuries of slopes

(D) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline. -->no info support this

(E) Injuries that occurred on the slopes of ski resorts made up a smaller percentage of ski-related injuries in 1980 than in 1950. -->the best. total ski-related injuries is made of injuries of slopes and injuries not of slopes. The latter is greater in 1980 than in 1953 (25%>10%), so the prior is lower in 1980 than in 1953

I am leaning more towards E
