Opponents of drug laws that forbid using marijuana argue that in a free country, people have the right to take risks with their bodies as long as the people do not cause harm to befall others as a result of taking the risks. This principle leads them to conclude that each person should have the right to decide for him or herself whether to use marijuana.

Which of the following, if true, most seriously weakens the conclusion drawn above?

(A) The rate of overdose fatalities in countries that do not have drug laws that forbid using marijuana is greater than the rate of fatalities in countries that do have such laws.
(B) Unlike cocaine or heroin, there is little evidence, if any, that marijuana is addictive.
(C) A greater percentage of fatal car accidents are caused by marijuana users than by alcohol users.
(D) There is no evidence to suggest that people suffer medical maladies as a result of second-hand marijuana smoke.
(E) Health insurance rates for all people are higher because of the need to pay for the increased medical care users of marijuana require.

(E) Health insurance rates for all people are higher because of the need to pay for the increased medical care users of marijuana require.

There are two issues with answer C here:

First, C says that a greater percentage of accidents are caused by marijuana *users*, not by marijuana *use*. If you read C and think it establishes that marijuana use leads to more accidents than alcohol use, you're falling into a correlation/causation trap. Marijuana users might cause more accidents, but marijuana may have nothing to do with it. Perhaps people who use alcohol can't afford to buy cars, and people who use marijuana can. Then naturally marijuana users will cause more accidents, since they're the only ones driving.

Second, without any information about how many people use marijuana and how many use alcohol, C is not at all useful. If, say, 99% of people use marijuana and 1% of people use alcohol, you'd expect marijuana users to cause a greater percentage of accidents only because there are so many more of them than alcohol users. Again, marijuana may have nothing to do with it. You might imagine a similar example: if you learned that a greater percentage of accidents were caused by people talking on cell phones than by people falling asleep while driving, you would not, from that alone, conclude that talking on a cell phone is more likely to cause an accident than falling asleep while driving. It's just that talking on cell phones is far more common than falling asleep while driving.

This principle leads them to conclude that each person should have the right to decide for him or herself whether to use marijuana.

Paraphrase: A person should have the right to have a free will unless and untill the person is not causing harm to others ?
Look for an answer choice where a person's free will is unintentionally causing troubles to others.

Which of the following, if true, most seriously weakens the conclusion drawn above?

(A) The rate of overdose fatalities in countries that do not have drug laws that forbid using marijuana is greater than the rate of fatalities in countries that do have such laws.
(B) Unlike cocaine or heroin, there is little evidence, if any, that marijuana is addictive.

(D) There is no evidence to suggest that people suffer medical maladies as a result of second-hand marijuana smoke.
(E) Health insurance rates for all people are higher because of the need to pay for the increased medical care users of marijuana require. Matches the paraphrase.

None of the other options create element of doubt here.E is clean and clear.

My two cents -

1. Even though greater % of accidents are caused by marijuana users than alcohol user,that does not confirm that marijuana users are harming other people more. Example : accidents % marijuana - 10, alcohol - 9 and rash driving- 40. A third cause is more pronounced than Marijuana. Where as In option E, marijuana users are clearly causing problem for others.

2.C is a classic example of an answer option where a comparison is made.Often such answer choices are not the 1 preference.This you will observe in number of practice questions.

In all C leaves many avenues open for assumption,where as E closes the gap all through.

More so, as most of the responsible users do, I do not attempt to answer a question if I get it wrong on first go.

Two years ago, the human resources department at Harrison's Technologies had 175 sexual harassment cases open, a number that at that time led all companies in the sector. At that time, a typical claim took six months to process and clear. In response to this high number, the CEO's Advisory Team published a comprehensive set of guidelines for training employees in the identification and avoidance of behaviors that could constitute sexual harassment. At this writing, the human resources department has only sixty sexual harassment cases open. Clearly, the guidelines published by the CEO's Advisory Team were effective in reducing the occurrence of new sexual harassment claims at Harrison's Technologies.
Which of the following, if true, most seriously weakens the conclusion above?

Two of the six members of the CEO's Advisory Team were found guilty of sexually harassing members of the secretarial staff
New paperwork and procedure, also introduced two years ago, has allowed the human resources department at Harrison's Technologies to process and close almost all new claims of sexual harassment in less than one month.
The human resources department at Anthony Information Industries, a principal rival of Harrison's with a similar number of employees, opened no new sexual harassment claims in the past year.
Independent consultants using scientifically designed surveys have found that the majority of current employees at Harrison's Technologies are not properly educated on exactly what behaviors constitute sexual harassment.
The majority of sexual harassment claims lead to the termination of employees found guilty; new employees hired to fill these positions need to be trained in the guidelines.

can someone help me with this question?
