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.

Question 1
Quote:
...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.

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
Quote:
Thus, the hygiene that helped prevent typhoid epidemics...

Therefore, if no modern hygiene, TYPHOID EPIDEMICS OCCUR. - (C)
