Automobile manufacturer: Recently developed defect-detection systems, although not yet proven to be completely accurate, should be purchased immediately for our plants. Automated inspections will help assembly-line workers detect flaws in materials.

Employee representative: Plants will not benefit from inadequately tested defect-detection systems. Failures in those systems could mislead the workers using them, allowing flaws to go undetected.

Which of the following, if true, would most strengthen the employee representative's objection?


A) Any automated system, no matter how rigorously tested, is susceptible to malfunction.

B) An automated packing system was successfully introduced by the manufacturer with only minimal testing.

C) Even though the new system will help detect some flaws, the probable system failures will cause even more flaws to go undetected.

D) Many flaws are missed due to the high stress levels experienced by assembly-line workers.

E) Defect-detection systems as they are currently used are more effective at detecting flaws in finished products than they are in raw materials.


I find "D" strengthens more, the first statement mentions about assembly line workers..to detect flaws..hence if they already miss out on flaws, the new system will fail.

A)Any automated system, no matter how rigorously tested, is susceptible to malfunction - Employee representative (ER) says that argues against inadequately tested systems. Irrelevant.

B) An automated packing system was successfully introduced by the manufacturer with only minimal testing - We are not sure about the connection between automated packing systems and automated defect detection systems. Irrelevant.

C)Even though the new system will help detect some flaws, the probable system failures will cause even more flaws to go undetected - This is in line with what the ER is saying and strengthens ER's argument. ER talks about system failures causing defects to go undetected. Correct.

D)Many flaws are missed due to the high stress levels experienced by assembly-line workers - ER is arguing against the defect detection systems. If anything, this statement weakens the argument of the ER by saying that the current process does not work and there is a need for alternate ways to detect defects.

E) Defect-detection systems as they are currently used are more effective at detecting flaws in finished products than they are in raw materials - ER does not argue about the efficacy of defect detection systems for different kinds of materials (i.e FG vs raw material). Irrelevant.

My answer is C.

I also agree with answer C and the comments made by unverifiedvoracity.

The ER doesn't disagree that the automated system could help, but believes that an inaccurate system would mislead the inspectors into a false sense of security with a false negative (negative being a none existence of a flaw). Who has a stronger position then becomes a question of whether the new system helps more or hinders more.

If the new system misses more flaws than it spots as indicated by C, and if we are happy to assume that the workers currently spot more flaws than they miss, then the ER's position has been strengthened. If the employees were making many errors already as in D, then like unverifiedvoracity says, that would weaken the ERs position. However the word many does not provide enough information to say that it definitively weakens the ER's position.

Manufac : DDS though not proven to be accurate at detecting flaws should be installed in plant to detect flaws.
Emp Rep : DDS will not be useful and mislead employees, some flaws will go undetected.


A)Any automated system, no matter how rigorously tested, is susceptible to malfunction.

Malfunctioning of the system is not the issue, we are looking for the results of an untested system.

B) An automated packing system was successfully introduced by the manufacturer with only minimal testing.

Out of scope

C)Even though the new system will help detect some flaws, the probable system failures will cause even more flaws to go undetected.

If some system failures go undetected then surely it strengthens the employee representatives views.

D)Many flaws are missed due to the high stress levels experienced by assembly-line workers.

Out of scope.

E) Defect-detection systems as they are currently used are more effective at detecting flaws in finished products than they are in raw materials.

Out of scope.

Hence only (C) strengthens the highlighted part of the employee representatives claim and is the answer !!
