CR 1
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.
(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.
(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.
(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.
(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.

The National Train Company of Country X has decided to offer its employees a classical music appreciation course free of charge in order to increase productivity. The decision was reached after a study was published confirming the positive effects of classical music on the human psyche: facilitating improved stress management and inducing a feeling of tranquility.
Which of the following, if true, most seriously strengthens the National Train Company's conclusion?
(A) A newspaper article appearing in the science section states that classical music is more conducive to sleep than Pop, Rock and Roll and Rhythm & Blues.
(B) The cost of the classical music appreciation course, per student, comes to 10% of the average monthly salary paid in the National Train Company.
(C) A survey handed to students in 10 separate music appreciation courses shows that music appreciation courses affect the musical tastes of only 20% of participants.
(D) Classical music appreciation courses are preferred by employees of large companies over Pop or House music appreciation courses.
(E) Classical music has been shown to have a positive effect on the digestive system, thus lowering the average days of sick leave among those who listen to it.
