I thought A, B, D all are flows in the reasoning.
A certain eye infection has been linked to exposure to a certain type of high-salinity sea water. While not dangerous, these infections are painful and often unnoticeable, at least to those who contract them. Over 80% of children ages 4-14 who bathed in a particular sea called "The White Sea" have contracted the infection in varying levels of severity. Although bathing in "The White Sea" does not always lead to a contraction of the infection, the only way to completely avoid the infection is to refrain from bathing in "The White Sea" and other Sea waters altogether.
Which of the following indicates a flaw in the author’s reasoning?
A) It relies on evidence about a specific place to make a recommendation about an entire class of such places.
: author collects evidence from "the white sea" and make a generalised statement about all seas so this presents a flaw in this part of the sentence: he only way to completely avoid the infection is to refrain from bathing in "The White Sea" and
other Sea waters altogether.
B) It assumes that one possible cause of a condition is the only cause of that condition.
This option point a flaw in this part of the senetence :
the only way to completely avoid the infection is to refrain from bathing in "The White Sea" and other Sea waters altogether.
D) It makes a generalization based on one segment of the population.
: Author has collected only evidence of "Over 80% of children ages 4-14 who bathed in a particular sea called "The White Sea" have contracted the infection in varying levels of severity" what about adult group, old age group. the only way to completely avoid the infection is to refrain from bathing in "The White Sea" and other Sea waters altogether. => this will fall apart then.
