In conclusion, the argument is unconvincing as it stands. To strengthen it, the author must
demonstrate that this country's consumers will in fact decrease their sugar consumption as a
result of their growing awareness of its health risks. The author must also provide dear
evidence that the demand for peanuts and the revenue from peanut production in this country
are likely to match the current demand for sugar and farm revenue from sugar production,
respectively. To better evaluate the argument we would need to compare the two countries'
climatic and soil conditions; we would also need to compare consumer tastes in Palin with
consumer tastes in the author's country.
Argument 90
The following appeared in a recommendation from the president of Amburg's Chamber of
Commerce.
"Last October the city of Belleville installed high intensity lighting in its central business district,
and vandalism there declined almost immediately. The city of Amburg has recently begun
police patrols on bicycles in its business district but the rate of vandalism there remains
constant. Since high intensity lighting is apparently the most effective way to combat crime, we
should install such lighting throughout Amburg. By reducing crime in this way, we can revitalize
the declining neighborhoods in our city."
Amburg's Chamber-of-Commerce president has recommended high-intensity lighting
throughout Amburg as the best means of reducing crime and revitnliT, ing city neighbor hoods.
In support of this recommendation the president points out that when Belleville took similar
action vandalism declined there almost immediately. The president also points out that since
Amburg's police began patrolling on bicycles the incidence of vandalism has remained
unchanged. The president's argument is flawed in several critical respects.
First, the argument rests on the unsupported assumption that in BeUeviUe the immediate
decline in vandalism was attributable to the lighting--rather than to some other
phenomenon-and that the lighting has continued to serve as an effective deterrent there.
Perhaps around the same time the city added police units or more after-school youth programs.
Moreover, perhaps since the initial decline vandals have grown accustomed to the lighting and
are no longer deterred by it. Without ruling out other feasible explanations for the decline and
showing that the decline was a lasting one, the president cannot reasonably conclude on the
basis of BelleviUe's experience that the same course of action would serve Amburg's
objectives.
Secondly, the president assumes too hastily that Amburg's bicycle patrol has been
ineffective in deterring vandalism. Perhaps other factors--such as a demographic shift or
worsening economic conditions--have served to increase vandalism while the bicycle patrol
has offset that increase. Thus without showing that all other conditions affecting the incidence
of vandalism have remained unchanged since the police began its bicycle patrol the president
cannot convincingly condude that high-intensity lighting would be a more effective means of
