(4)When was the survey conducted? 调查时间：做调查的时间和得出结果的时间要足够近。
A threshold problem is that the editorial neglects to indicate how recently he survey was actually conducted. When samples are used to make general claims about a particular group, the samples should be close enough in time to the generalization. All we know in this editorial is that the survey was recently published. The less recent the survey itself, the less reliable the results to indicate current interest levels.

The following appeared in a memo from the customer service division to the manager of Mammon Savings and Loan:
“We believe that improved customer service is the best way for us to differentiate ourselves from competitors and attract new customers. We can offer our customers better service by reducing waiting time in teller lines from an average of six minutes to an average of three. By opening for business at 8:30 instead of 9:00, and by remaining open for an additional hour beyond our current closing time, we will be better able to accommodate the busy schedules of our customers. These changes will enhance our bank’s image as the most customer-friendly bank in town and give us the edge over our competition.”
