The percentage of cases of chemical poisoning in which workers in the AB adhesive factory are involved, such cases being characterized by symptoms including vomiting, blurry vision, and constricted respiration, is not nearly as high as the percentage constructed by correctly consolidating the figures from reports conducted by similar chemical production industries and forming an accurate average. However, despite complaints about their inherent capability to cause discomfort to the face and neck area and to reduce the vision field by up to 40%, gas masks equipped with twin filters are a mandatory item for all employees working in the operational sectors of the AB adhesive factory.
Which of the following, if true, best reconciles the seeming discrepancy described above?
(A) The percentage of chemical poisoning cases, or, in the case of companies that produce consumer products, the percentage of physical injuries, is often an indication of a manufacturer's professionalism. -
does not address the discrepancy between the factory’s percentage and the industry average.(B) Whether of the single or twin filter type, gas masks, despite being extremely effective for protection from the inhalation of toxic substances, are completely redundant in cases of exposure to gases that enter through skin pores.-
not explain why the factory has a lower percentage of poisoning cases(C) Since all adhesives contain ethanol and exylene, when comparing the frequencies of toxicity cases in factories, the inclusion of manufacturing industries that do not produce such chemicals in any step of their processes would only lead to misinformation.-
irrelevant (D) Before the policy of the obligatory wearing of twin-filter gas masks had been employed, it was not at all rare that the AB adhesive factory's frequency of chemical poisoning cases would match the industry average. -
correct,Address the proper discrepancy with conclusion.
(E) The AB adhesive factory, prior to the implementation of the rule concerning the wearing of twin-filter gas masks, employed a higher number of people, both in the operational and administrative sectors, than it does today.-
