Marketing executive for Magu Corporation: Whenever Magu opens a manufacturing facility in a new city, the company should sponsor, or make donations to, a number of nonprofit organizations in that city. Doing so would improve Magu' s image in the community, and thus the money spent on such charitable ventures would lead to increased sales. Which statement would, if true, point to the most serious weakness in the marketing executive's advice? ['If market conditions change, Magu may have to close any such facility or relocate it.', 'Some nonprofit organizations are poorly organized, so money donated to them would be of little benefit to the community.', 'Spending on charitable ventures would require Magu to decrease direct advertisements, which are the most effective means of reaching its target customers.', 'Magu sells its products internationally, so sales in any one city represent only a small portion of total revenue.']
