### HideShow timer Statistics

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 can bde 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.

This MUST BE TRUE QUESTION.

Derive
Facts (Premises) --------> Conclusion

Remember, any information outside from the Stimulus is not accepted. We must use the facts provide in the Stimulus

(A) No Where it is mentioned in the Stimulus that "A(Injuries at Slope)causes B (Injuries at Premises). Author just presented the two facts.
(B) No where it is mentioned the "Skiers consumed alcohol" . Just mentioned that Injuries increases with the amount
of alcohol consumed per skier.
(c) The technology of ski boots and bindings affects the incidence of each type of ski-related injury.
"This could be ture" --> You can't generalize. For e.g. in 2000 new technology only affect one type other is constant.
(d) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline.
" This may be true or may not be true" .. for 1950 to 180 it is true.. for 1980 to 2000 --> May not be true.
(e) In 1980 "slope injuries"/"prem injuries" = 3/250
In 1950 "slope injuries"/"prem injuries" = 9/100
3/250 < 9/100 --> this true.

E is the correct answer. Similar approach as Suresh.
All other options need you to *assume* something and on conclusion question, you are not supposed to assume anything. Answers could be as simple as restatement of some part of the stem

(e) In 1980 "slope injuries"/"prem injuries" = 3/250
In 1950 "slope injuries"/"prem injuries" = 9/100
3/250 < 9/100 --> this true.

Im not so sure this is a proper calculation

shouldnt it be just of hypothetical 1,000 injuries

in 1980 250 (25%) are non slope
in 1950 (10%) are non slope

thus E is obviously correct. choice E doesnt put into context per 1,000
