In Brazil, side-by-side comparisons of Africanized honeybees and the native honeybees have shown that the Africanized bees are far superior honey producers. Ttherefore, there is no reason to fear that domestic commercial honey production will decline in the United States if local honeybees are displaced by Africanized honeybees. Each of the following, if true, would weaken the argument EXCEPT: ['If Africanized honeybees replace local honeybees, certain types of ornamental trees will be less effectively pollinated.', 'Commercial honey production is far more complicated and expensive with Africanized honeybees than it is with the more docile honeybees common in the United States.', 'The area of Brazil where the comparative study was done is far better suited to the foraging habits of the Africanized honeybees than are most areas of the United States.', 'In the United States a significant proportion of the commercial honey supply comes from hobby beekeepers, many of whom are likely to abandon beekeeping with the influx of Africanized bees.']
