It is clearly E

The argument is saying that those who marry young tend to live longer, NOT because they are married, BUT because they tend to not have unhealthy habits.

E strengthens the argument saying that among young people, those who do not have unhealthy habits but DO NOT marry live as long as the ones that DO marry.

Will go with E.

The argument is that marriage has nothing to do with people living longer.
To strengthen the argument we need to show something simmilar.

E does that.

The author argues that studies have found young people marrying earlier to live a longer live.
And E says that a young person with similar habits to another yougn man gettign married has the same chance of living longer as the person marrying. Hence marriage is not a factor in their longer lives.

It is true of both men and women that those who marry as young adults live longer than those who never marry. This dose not show that marriage causes people to live longer, since, as compared with other people of the same age, young adults who are about to get married have fewer of the unhealthy habits that can cause a person to have a shorter life, most notably smoking and immoderate drinking of alcohol.

Which of the following, if true, most strengthens the argument above?

A. Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.
B. A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.
C. A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.
D. Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.
E. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

Please, provide your explanations


Choose E here.

E affirms that marriage doesn't impact on life expectancy prolongation. Hence, the conclusion that marriage causes people to live longer is strengthen.

B) Incorrect- Irrelevant
C) Incorrect- Out of the scope
D) Incorrect - Here the sentence is people who marry as young adult. But in the premises it is " young adults who are about to get married".

Prethinking: we are interested in the group of people, who are about to get married --> people who are already married - out of scope
Second: The conclusion says, that people that tend to marry are healthier already before the marriage, it's not a marriage that makes a person healthier.

A) Some causes after marriage -> out of scope
B) already married - out of scope (actually weakens the conclusion)
C) tempting (people who don't smoke/drink are seeking for a partner that shares his or her views and it's unlikely that a person and partner who don't smoke/drink before the marriage, can start smoking or drinking - but it's a further assumption, a weak argument)
D) Again, something happens after marriage -> out of scope
E) Bingo ! It's not a marriage causing young adults live longer, that the healthy way of life, that enables the longer live

Please correct me, i f my reasoning is false.

(A) Repeats the info and doesn't strengthen.
(B) Contradicts the claim that newly engaged couples are just as safe as young adults who are married.

E. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

If you don't have bad habits, you live longer. That relationship is further established with a control group of adults who have never married and have healthy habits. This attempts to causally relate healthy habits with longevity, just as the argument's premise is based on. Answer E.

A. Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm. Nope. Says marriage causes x.

B. A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried. Nope. Says marriage causes x.

C. A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately. Nope. Prompt says that this group is less likely to get married. Also, the statistic would have already taken this into account.

D. Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life. Nope. Says marriage causes x.

E. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry. Winner winner chicken dinner. Strengthens argument by showing if certain characteristics are the same, married and non-married folk live to be, on average, the same age

+1 Kudos if my post helped clarify the problem!

Which of the following, if true, most strengthens the argument above?

Sports? Irrelevant

B. A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.
This is a wekner. It is correlating the marriage to giving up of bad habits.

C. A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.
Irrelevant

D. Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.
So they are getting rid of the bad habits after the marrige, but the premise is talking about the people with unhealthy habits before the marrige.

E. Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.
Correct. Unhealthy habits before marriage = No healthy habits + No marriage (correct comparison)

Strenghten: The reason people who get marry lives longer is not because they got married but because they have healthier habits

A) Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm. The argument is not talking about body harm. It is talking about habits.
B) A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried. This answer weakens the arguments because says that married people give up their unhealthy habits.[/b]
C) A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately. The argument is not talking about who is going to marry who.
D) Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life. This answer weakens the argument like B because this argument says that people will give up an unhealthy habit after marriage and don’t go back to it.
E) Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.
This strengthens the argument because it stablishes that people who don’t have bad habits live longer, no matter if they are married or not.

If there was another option which read -" Among the young adults who are married , there are may with immoderate drinking habits and smoking habits who have the same life expectancy as the one who is unmarried and drinks immoderately and smokes" .

This would also strengthen the argument, right?

THIS A CLASSIC EXAMPLE OF CAUSE AND EFFECT STRENGTHEN ARGUMENT

FEW TIPS BEFORE WE ANALYSE THE ARGUMENT :

A. Eliminate any alternate causes for the stated effect
Because the author believes there is only one cause (the stated cause in the argument), eliminating other possible causes strengthens the conclusion.

B. Show that when the cause occurs, the effect occurs
Because the author believes that the cause always produces the effect, any scenario where the cause occurs and the effect follows lends credibility to the conclusion.This type of answer can appear in the form of an example.

C. Show that when the cause does not occur, the effect does not occur
Using the reasoning in the previous point, any scenario where the cause does not occur and the effect does not occur supports the conclusion. This type of answer also can appear in the form of an example.

D. Eliminate the possibility that the stated relationship is reversed
Because the author believes that the cause and effect relationship is correctly stated, eliminating the possibility that the relationship is backwards (the claimed effect is actually the cause of the claimed cause) strengthens the conclusion.

E. Show that the data used to make the causal statement are accurate, or eliminate possible problems with the data
If the data used to make a causal statement are in error, then the validity of the causal claim is in question. Any information that eliminates error or reduces the possibility of error will support the argument.


As per the argument

Marriage (does not lead)-----> Longer life

Healthy habits ------> Longer Life
Strengthener would be an option which gives an instance that healthy habits lead to longer life and marriage does not lead to longer life

Only option E says that Among people who as young adults neither drink alcohol immoderately nor smoke(i.e don't indulge in unhealthy habits), those who never marry live as long as those who marry.

D was certainly tricky. however there is no mention of resumption of habits in the argument. also, "resume" adds another factor/data point to look at and thus we wd need comparisons of this factor

E. isolates and proves clearly that it is the fewer unhealthy habits that cause lengevity

The Official Guide for GMAT Review 13th Edition, 2012

Practice Question
Question No.: CR 118

Those who marry as young adults live longer than those who don't marry.
Young adults about to get married (not married already so marriage not responsible) have fewer unhealthy habits.

Conclusion - Marriage doesn't give you longer life, fewer unhealthy habits does.

(A) Marriage tends to cause people to engage less regularly in sports that involve risk of bodily harm.

Marriage makes people safer. Doesn't help our argument.

(B) A married person who has an unhealthy habit is more likely to give up that habit than a person with the same habit who is unmarried.

Marriage causes a person to have a healthier life. Doesn't help our argument.

(C) A person who smokes is much more likely than a nonsmoker to marry a person who smokes at the time of marriage, and the same is true for people who drink alcohol immoderately.

Irrelevant

(D) Among people who marry as young adults, most of those who give up an unhealthy habit after marriage do not resume the habit later in life.

We don't know how married people who give up compare with unmarried people who give up. We don't know whether unmarried people resume bad habits later in life after giving them up once.
If marriage causes people to give up and not resume, marriage is responsible for healthier life.
Doesn't strengthen our case.

(E) Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

Exactly. Tells us that marriage or no marriage has no impact on longevity. Those who don't have bad habits live longer than those who have bad habits.

Answer (C)

Hi VeritasKarishma
The first line of the argument says
Those who marry as young adults live longer than those who don't marry.

But E says among young adults,both unmarried and married if have good habits live longer but premise explicitly mentions that those who marry as young live longer.
Isnot it direct contradiction of the premise ?

No, it is not contradictory to the argument.

Both the statements given below can be true at the same time:
- It is true of both men and women that those who marry as young adults live longer than those who never marry.
- (E) Among people who as young adults neither drink alcohol immoderately nor smoke, those who never marry live as long as those who marry.

It is always about averages.
Say there are 100 married people and 100 unmarried. Say average life of married people is 80 while that of unmarried people is 70. Then, our first statement holds.
Say of the 100 married people, 70 have no bad habits and of the 100 unmarried people, 20 have no bad habits. Say we find that the avg lifespan of these 70 people is 85 yrs and the avg lifespan of these 20 people is also 85 yrs. This is what option (E) says.
