LSAT Question Complete Explanation

This is a "Must Be False" (MBF) question type, which asks us to identify the answer choice that does NOT conflict with the letter writer's view. Let's first summarize the letter writer's main points: vexone has been used effectively against all cockroach species that infest North America, and Roach Ender, which contains vexone, has been tested and proven to control these species. Now, let's examine each answer choice in detail:

a) Vexone is effective against only two species of cockroach that infest North America.

This statement conflicts with the letter writer's view that vexone is effective against all species that infest North America, so this is not the correct answer.

b) Not all of the major species of cockroach that infest North America can be controlled by Roach Ender.

This statement also conflicts with the letter writer's view, as they claim that Roach Ender, which contains vexone, is effective against all species that infest North America. Therefore, this is not the correct answer.

c) Every species of cockroach that infests North America can be controlled by vexone.

This statement aligns with the letter writer's view and does not conflict with it. Thus, this is the correct answer.

d) The cockroach infestations that have been combated with vexone have not included all of the cockroach species that infest North America.

This statement conflicts with the letter writer's view that vexone has been effectively used against all species that infest North America. Therefore, this is not the correct answer.

e) Roach Ender was tested against exactly 4,000 cockroach species that infest North America.

This statement conflicts with the letter writer's view that there are more than 4,000 species that infest North America, and Roach Ender has been tested and proven effective against all of them. Therefore, this is not the correct answer.

In conclusion, the correct answer is C, as it does not conflict with the letter writer's view.
