Complete Question Explanation
(See the complete passage discussion here: lsat/viewtopic.php?t=13636)
The correct answer choice is (A)
Another Cannot Be True question, the correct answer to this one will be the one that cannot be true, based on the assumption that the passage’s statements about prions are accurate.
Answer choice (A): This is the correct answer choice. Prions are pathogens which, the author points out, lack nucleic acid and are instead composed mostly of protein. Since this choice presents the claim that nothing that lacks nucleic acid is a pathogen, it is clearly inaccurate and must therefore be the right answer to this Cannot Be True question.
Answer choice (B): The accuracy of this answer choice is confirmed by the author in the second paragraph, and this is a central point of the passage as well; this therefore cannot be the right answer to this Cannot Be True question.
Answer choice (C): The passage provides that a pathogen is a disease-causing agent, and that infections can only take place when the pathogenic agent is able to reproduce and create a viable presence in the organism. There is no implication that any pathogens exist that are unable to cause an infection. Since the choice is not refuted by the passage, it can be ruled out of contention in response to this Cannot Be True question.
Answer choice (D): In the final paragraph the author provides that it is now generally accepted that CJD is caused by prions, a new addition to the list of pathogens, confirming this choice to be accurate according to the passage. Since this question requires the choice that Cannot Be True, this choice must be ruled out.
Answer choice (E): The passage provides that prions are a fifth category of pathogenic agent, so the four pathogens listed are not the only ones. Since this choice passes the Fact Test, it cannot be the right answer to this Cannot Be True question.
