Although the organic farms in the agricultural community of Greendale are destined to shut down within the next decade as a result of competition from the organic mega-farm Full Foods, the farmland will not go unused for long. In the decade since the opening of OmniFoods, Inc., a non-organic farm conglomerate, a new owner has bought and reopened every farm in Greendale that has shut down due to competition with OmniFoods, Inc.
Which of the following, if true, most seriously weakens the argument?

1. Many customers of OmniFoods, Inc. are expected to buy less nonorganic food than they did before the Full Foods farm opened in Greendale.
2. The new farms that have opened in the agricultural community of Greendale since OmniFoods, Inc. opened have been primarily organic farms.
3 Many farms in Greendale sell produce that is not available to buy from either OmniFoods, Inc. or from Full Foods.
4. The demand for organic food is expected to increase at a faster rate over the next decade than at any time over the past fifty years.
5. The agricultural community of Greendale currently has more different farms operating within its borders than it ever has before
