For Question no. 6, How is B wrong ?

Hello,

According to lines 16 to 22, "Interest in outdoor recreation began to grow in the recently late nineteenth century". That's why letter B is wrong.

Note that the transmission of Lyme disease "occurred sporadically [in nineteenth century]", but became prevalent recently when "Interest in outdoor recreation began to grow".

Best,

wonderful observation brought out. :thumbup:

5. Which of the following best describes the organization of the passage?

A A paradox is stated, discussed and left unresolved.
B Two opposing explanations are presented, argued, and reconciled.
C A theory is proposed and is then followed by descriptions of three experiments that support the theory.
D A generalization is stated and is then followed by three instances that support the generalization.
E An argument is described and is then followed by three counterexamples that refute the argument.

I can understand that D is a better option, but I cannot able to figure out why it is considered as a generalization. Can someone please explain it?

Hi Teja

The "generalization" referred to in option (D) is the following sentence:

In analyzing the latter, scientists have discovered the importance of social and ecological factors to epidemics.

This makes a sweeping statement that "social and ecological factors" are important to epidemics caused by virus and bacteria that have not undergone any significant change.

The three examples that follow - polio, Lyme disease and dengue - serve as strengtheners to support this generalization. All of them focus on the "social and ecological factors" that have caused these three diseases respectively to become epidemics. Hence, option (D) best explains the organization of the passage.

Hope this helps.

The hard part about Question 1 is that the relevant information is surrounded by irrelevant information. Lines 7-12 appear to be relevant. However, all you need to read is

The Official Guide for GMAT Verbal Review,2nd Edition, 2009

Practice Question
Question No.: RC 12 ~ 17
Page: 26
Although genetic mutations in bacteria and viruses can lead to epidemics, some epidemics are caused by bacteria and viruses that have undergone no significant genetic change. In analyzing the latter, scientists have discovered the importance of social and ecological factors to epidemics. Poliomyelitis, for example, emerged as an epidemic in the United States in the twentieth century; by then, modern sanitation was able to delay exposure to polio until adolescence or adulthood, at which time polio infection produced paralysis. Previously, infection had occurred during infancy, when it typically provided lifelong immunity without paralysis. Thus, the hygiene that helped prevent typhoid epidemics indirectly fostered a paralytic polio epidemic.
Another example is Lyme disease, which is caused by bacteria that are transmitted by deer ticks. It occurred only sporadically during the late nineteenth century but has recently become prevalent in parts of the United States, largely due to an increase in the deer population that occurred simultaneously with the growth of the suburbs and increased outdoor recreational activities in the deer's habitat. Similarly, an outbreak of dengue hemorrhagic fever became an epidemic in Asia in the 1950's because of ecological changes that caused Aedes aegypti, the mosquito that transmits the dengue virus, to proliferate. The stage is now set in the United States for a dengue epidemic because of the inadvertent introduction and wide dissemination of another mosquito, Aedes albopictus.

Why's choice B in question 6 incorrect?
I thought that choice A was wrong because it duplicates with the fact that is already stated in the passage.

Question 6


adityaganjoo
Although you have already explained what makes (A) right in Question 6, could you please explain what makes (B) wrong?
Show more
The author asserts that "social and ecological factors" can lead to epidemics, and his/her discussion of Lyme disease is an example of this assertion.

According to the author, Lyme disease was "sporadic" in the late nineteenth century and has "recently become prevalent." The ecological factor that led to this increase was "an increase in the deer population," and the social factors that led to this increase are "the growth of the suburbs and increased outdoor recreational activities in the deer's habitat."

To answer question 6, we have to strengthen the argument that these social and ecological factors led to the increase in Lyme disease.

Quote:
B Interest in outdoor recreation began to grow in the late nineteenth century.
Show more

Hmm. The author tells us that increased outdoors activity is one reason why people get Lyme disease NOW, when they didn't get it so often in the late nineteenth century. (B) seems to undermine this reasoning -- if people actually WERE increasingly interested in outdoor recreation in the nineteenth century, then perhaps the author is wrong about this factor playing a role in the recent prevalence of Lyme disease.

If anything, (B) actually weakens the author's argument that outdoor activity can explain the increase in Lyme disease.

(B) is out for question 6.

I hope that helps!

1. The passage suggests that a lack of modern sanitation would make which of the following most likely to occur?

D An epidemic of paralytic polio among infants
- "Previously, infection had occurred during infancy, when it typically provided lifelong immunity without paralysis."
--> no paralysis among infants

E An epidemic of paralytic polio among adolescents and adults
- "modern sanitation was able to delay exposure to polio until adolescence or adulthood, at which time polio infection produced paralysis." --> modern sanitation = delay polio until adulthood + produce paralysis. Thus, without modern sanitation = no paralytic polio among adolescents and adults.

The passage tells us that before modern sanitation, polio infection occurred during infancy, when it "provided lifelong immunity without paralysis." So basically, without modern sanitation, you might expect polio to infect infants, but not to cause paralysis.

Notice that (D) talks about an "epidemic of paralytic polio among infants." Since we wouldn't expect polio to cause paralysis in infants, (D) is incorrect.

I hope that helps!

1. The passage suggests that a lack of modern sanitation would make which of the following most likely to occur?

"Thus, the HYGIENE that helped PREVENT TYPHOID epidemics
indirectly fostered a paralytic polio epidemic" - Remove HYGIENE then we get the reverse of PREVENTING TYPHOID

ANSWER: (C) An epidemic of typhoid

2. According to the passage, the outbreak of dengue hemorrhagic fever in the 1950's occurred for which of the following reasons?

"an outbreak of dengue hemor-
rhagic fever became an epidemic in Asia in the 1950's
because of ecological changes that caused Aedes aegypti,
(25) the mosquito that transmits the dengue virus, to proliferate" - PROLIFERATE / INCREASE in NUMBER

ANSWER: (B) The mosquito Aedes aegypti became more numerous.


3. It can be inferred from the passage that Lyme disease has become prevalent in parts of the United States because of which of the following?

"increased outdoor recreational activities in the
deer's habitat" - MORE EXPOSURE TO DEER

ANSWER: (E) An increase in the number of humans who encounter deer ticks


4. Which of the following can most reasonably be concluded about the mosquito Aedes albopictus on the basis of information given in the passage?

"The stage is now set in the United States for a
dengue epidemic because of the inadvertent introduction
and wide dissemination of another mosquito, Aedes
albopictus" - newly introduced... hence, not native to the US...

A It is native to the United States. They are newly introduced. Hence, out!
B It can proliferate only in Asia. They can cause epidemics in US. Hence, out!
ANSWER: (C) It transmits the dengue virus.
D It caused an epidemic of dengue hemorrhagic fever in the 1950's. This is another breed of mosquito
E It replaced Aedes aegypti in Asia when ecological changes altered Aedes aegypti's habitat. not mentioned

5. Which of the following best describes the organization of the passage?

A A paradox is stated, discussed and left unresolved. Contrasting views mentioned initially but the discussion did not revolve around that...
B Two opposing explanations are presented, argued, and reconciled.Two views introduced but the discussion did not revolve around that

C A theory is proposed and is then followed by descriptions of three experiments that support the theory. no such experiments mentioned

ANSWER: (D) A generalization is stated and is then followed by three instances that support the generalization.

E An argument is described and is then followed by three counterexamples that refute the argument. the examples are not use as counterexamples but just examples of epidemics without genetic evolution

6. Which of the following, if true, would most strengthen the author's assertion about the cause of the Lyme disease outbreak in the United States?

ANSWER: (A) The deer population was smaller in the late nineteenth century than in the mid-twentieth century.
If the deer population was just same as population to day, then the increase in population will be an invalid explanation for the Lyme disease. This eliminate that possibility.


i'm confused about question number 6 - the passage already states that the deer population was smaller in the past. choice a is merely re-stating this fact. strengthening should bring something out of scope into the picture. would love if anyone can explain here. thanks!
Hi

I have the same question. It seems that A is merely a paraphrase, and I would expect something slightly out of scope to lend more support for the argument.

Thanks

I think this follows a very simple reasoning.

A The deer population was smaller in the late nineteenth century than in the mid-twentieth century.
If it ( Deer population ) increased in 20th CE it supports the reason mentioned in passage

B Interest in outdoor recreation began to grow in the late nineteenth century.
If it ( outdoor recreation ) increased in 19th CE it doesn't support why the increase was seen only in 20CE ( that means there is definitely another contributing factor that started in 20th century ) that is even if we assume increased interest is proportional to increased activity
Additionaly an added interest doesn't necessacrily mean increase in outdoor activity
generally a wrong ans has multiple flaws if observed minutely

Thus A is a stronger argument !­
