During the past five years, more than five thousand Maltanians have drowned in boating accidents. Figures released by the country's Boating Association show that ninety percent of the victims were not wearing life jackets at the time of their accidents. This information indicates that by wearing life jackets, boaters can reduce their risk of drowning if they are involved in a boating accident.
Which of the following best supports the argument above?
1. Most of the drowning victims were not wearing lifejackets at the time of their accidents
2. More than ten percent of those involved in boating accidents were wearing life jackets at the time
3. Most boating accidents do not result in drowning
4. The boating association is not funded by a company that manufactures life jackets
5. Many of the drowning victims were knocked unconscious during their accidents

Reason : Out of those involved in accidents, 90% victims were not wearing LF and only 10% victims were wearing LF. so wearing LF reduces the chance of drowning.
example : 110 members , 100 victims, 90 not wearing LF and 10 wearing LF. 10 people saved their life by wearing LF.
There are better ways to eliminate other option, our goal is to mark correct option & move on
Reason why others are not correct
1- This we already know "Figures released by the country's Boating Association show that ninety percent of the victims were not wearing life jackets at the time of their accidents"
we need more info to support conclusion based on this premise
3- we are concerned about accidents that result in drowning so that importance of life jackets can be evaluated
4- dose not matter if company if funded or not
5- victims's unconsciousness does not supportm it is irrelevant

If wearing lifejackets did not affect the probability of drowning, the percent of boaters who drown while wearing lifejackets should be equal to the percent in accidents who are wearing life jackets.
Conversely, the percent who drown while NOT wearing lifejackets should be equal to the percent in accidents who don't wear lifejackets.
We know the percent who drowned while wearing lifejackets was 10%. B, however, tells us that the percent in accidents who WERE wearing lifejackets is greater than 10%. Therefore the lifejackets are saving lives.
