　　1.The following appeared in a newsletter offering advice to investors¹.

　　"Over 80 percent of the respondents to a recent survey indicated a desire to reduce their intake² of foods containing fats and cholesterol³, and today low-fat products abound⁴ in many food stores. Since many of the food products currently marketed by Old Dairy Industries are high in fat and cholesterol, the company's sales are likely to diminish greatly and their profits will no doubt decrease. We therefore advise Old Dairy stockholders to sell their shares and other investors not to purchase stock in this company."
 
　　2.The following appeared in a letter to the editor of a local newspaper from a citizen of the state of Impecunious⁵.

　　"Two years ago our neighboring state, Lucria, began a state lottery⁶ to supplement tax revenues for education and public health. Today, Lucria spends more per pupil than we do, and Lucria' s public health program treats far more people than our state's program does. If we were to establish a state lottery like the one in Lucria, the profits could be used to improve our educational system and public health program. The new lottery would doubtless be successful, because a survey conducted in our capital city concludes that citizens of Impecunious already spend an average of $50 per person per year on gambling⁷."
 
　　3.The following appeared in a letter to the editor of the Walnut⁸ Grove⁹ town newspaper.

　　"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ---which, like ABC, currently has a fleet of 20 trucks---has ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."
 
　　4.The following appeared in an editorial in a Prunty County newspaper.

　　"In an attempt to improve highway safety, Prunty County recently lowered its speed limit from 55 miles per hour to 45 on all major county roads. But the 55 mph limit should be restored, because this safety effort has failed. Most drivers are exceeding the new speed limit and the accident rate throughout Prunty County has decreased only slightly. If we want to improve the safety of our roads, we should instead undertake the same kind of road improvement project that Butler County completed five years ago: increasing lane widths and resurfacing rough roads. Today, major Butler County roads still have a 55 mph speed limit, yet there were 25 percent fewer reported accidents in Butler County this past year than there were five years ago."
