Last month, four industrial printing presses manufactured by Hawthorne Heavy Machinery and owned by Scarlet Ink Publications broke down in an industrial accident. In response, Scarlet Ink Publications ordered four new printing presses as replacements, from Hawthorne. This decision surprised many in the publishing industry because, ordinarily when a product fails repeatedly, users do not buy that product again.

Which of the following, if true, provides the best indication that Scarlet Ink Publishing’s decision was logically well supported?

A. Although only one of Hawthorne Heavy Machinery’s printing presses broke down during the previous year, the firm’s competitors had a perfect safety record in the same period.
B. Hawthorne Heavy Machinery had to replace many of its employees because they went to work for a competing firm.
C. The Occupational Safety and Health Administration issued new guidelines for printers in order to standardize the safety requirements that govern industrial maintenance.
D. The trade union pressured two major publishers into purchasing safer printing presses so that workers would be safer while operating the machines.
E. The Hawthorne Heavy Machinery printing presses broke down due to operator error, but because of the excellent quality of the printing presses, the damage to the facilities was minimal.

Some hotels in California cater almost exclusively to visiting business executives and government officials and rarely have bookings by families with children. Yet, these hotels also have strong ties with companies specializing in entertaining young children.

Which of the following, if true, best reconciles the seeming discrepancy described above?

A. The companies specializing in entertaining young children buy their materials from distributers outside of California.
B. For several weeks during the summer, these hotels become popular destinations for daylong parties hosted by large organizations for employees and their families.
C. Most guests who stay at these hotels prefer to seek entertainment elsewhere rather than at the hotel itself.
D. The few families that stay at these hotels come in groups of four to five, are friendly with one another, and share the cost of the stay.
E. Entertainment provided for young children by outside companies is as enjoyable as that provided by the hotel.

Due to certain persistent limitations in the technology, many early buyers of virtual reality systems apparently lost interest in buying new virtual reality games to run on their systems. The sale of virtual reality games is still going strong because the number of homes with virtual reality systems is still growing. However, businesses distributing virtual reality games will face hard times because the market for virtual reality systems is likely to saturate soon.

Which of the following, if true, would most seriously weaken the conclusion above?

A. The market for virtual reality systems is considered saturated only after seventy percent of all homes have at least one such system.
B. Early buyers of novel products are always quicker to acquire novelties, but also quicker to tire of them than other buyers.
C. Customer satisfaction surveys reveal that few of the early buyers of virtual reality systems had any complaints regarding this new product’s performance aspects.
D. Several games specifically designed to be played in virtual reality form a sizeable proportion of all the products handled by retailers of virtual reality games.
E. Shrinking markets generally intensify competition among businesses, leading to the failure of several marginal businesses.
