(See the complete passage discussion here: lsat/viewtopic.php?t=11562)
The correct answer choice is (A)
The organization of the passage is discussed in the VIEWSTAMP analysis above, and is nicely expanded upon by correct answer choice (A): The question about pathogens is presented, the perspective of “some biologists” is offered in response, implying that the more indirect the transmission the more virulent the pathogen in general. Finally, two exceptions to this general rule (diphtheria and tuberculosis) are presented.
Answer choices (B), (C), (D), and (E) are all wrong because they all include the component, the two examples of diphtheria and tuberculosis are not presented in order to illustrate the biologists’ explanation or implications thereof. They are presented to exemplify exceptions to the rule which links greater virulence to indirectly transmitted pathogens in general.
