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!
