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.
16. 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.

17. 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.

E and B stand out to me.

17 is pretty obvious and 16 is a little bit convoluted in that you actually have to do the math. But a good hint is that none of the other choices have math in them for you to rule out one or the other.

9 injuries in 1950 on slope.

remainder of all are 10%, means 9 injuries are 90% of all

So remainder =1 and total =10

3 injuries in 1980 on slope.

all other type of injuries rose to 25% of all injuries.

if there are only two types of injuries, then 3 injuries are 75% and 1 injury is 25%

E is saying 3/4 < 9/10 Correct right?

If you think abstractly, E will make a lot of sense.

16. 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, it is that the relative figure increases, not that the estimated figure increases
(B) The amount of alcohol consumed per skier increased between 1950 and 1980 --> not mentioned. The information in the passage is just about increase of alcohol consumed per skier, which may occur within 1980
(C) The technology of ski boots and bindings affects the incidence of each type of ski-related injury -->it does affect on the injuries occurring on the slopes of ski resort, but no certainty for its affect on other kind of injuries in ski resort
(D) If the technology of ski boots and bindings continues to advance, the incidence of ski-related injuries will continue to decline --> not mentioned
(E) Injuries that occurred on the slopes of ski resorts made up a smaller percentage of ski-related injuries in 1980 than in 1950 --> get it: in 1950, slopes injuries made of 90%, in 1980 they made of 75%

17. 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 -->no conflict
(B) A skier was less likely to be injured on the slopes in 1950 than in 1980 -->yep
(C) The reporting of ski injuries became more accurate between 1950 and 1980 -->no conflict
(D) The total number of skiers dropped between 1950 and 1980 -->no conflict
(E) Some ski-related injuries occurred in 1980 to people who were not skiing -->no conflict

A) the number of ski injuries that occurred on the slopes was greater in 1980 than in 1950.
The information is given for the no/1000 in the passage. So it is possible the total no of skiers increased in the resort since 1950. so ratio is still low in 1980 but still the total injuries can be high as suggested by A. Hence not conflicting.
