This winter, we are studying the Analytical Writing Assessment (AWA) task of the GMAT. Questions used are all from the Pool of Sample Topics available in the Official Guide. Be prepared for that some of the questions will look familiar when you actually take the test.

　　Now, we will be reading the question:

　　「Question No. 13」

　　The following appeared as part of a campaign to sell advertising time on a local radio station to local businesses:

　　“The Cumquat Café began advertising on our local radio station this year and was delighted to see its business increase by 10 percent over last year’s totals. Their success shows you how you can use radio advertising to make your business more profitable.”

　　Introduction

　　略

　　Body

　　The first point of doubt is whether the 10-percent increase in the café’s business represents an increase in its profits. ← 首先，直接指出疑点的核心。然后，具体分析我质疑的原因 → ‘Business’ is a rather vague and general concept, which may represent the café’s sales or number of customers. Since the café may have reduced its prices and profits to make greater sales or number of customers, the café may not have been profitable during the year. 【常见逻辑疑点：偷换概念问题。】

　　← 两个逻辑疑点之间的联系(上一点提到了价格下降，下一点就直接以此引出它因问题)→

　　At this point, since price reduction may also have contributed to the increase of business, the effectiveness of radio advertising is dubious. As a matter of fact, since many other factors, such as better chefs or table service, or renovation of the dinning environment, that may also have led to the increase of business are not ruled out, the author cannot be sure that the business increase is credited to radio advertising. 【常见逻辑疑点：它因问题。】

　　基于以上两段的小总结：写作中的两种常用句型有二

　　之一是“原因—结果”句型(关键词被黄色高亮标出)

　　In addition, even if the radio advertising has been an effective way of promoting the business during this year, it may no longer have the effect in the future. If it was only during this year that people listened to the radio and received the café’s promotional advertisements, radio will no longer have the effect of promoting businesses with its loss of listeners. 【常见逻辑疑点：时间问题：提示词：this year】

　　Also, the radio advertising may have been effective only in the local area where the Cumquat Café is based, probably because the local residents listen to the radio. However, if this medium of advertising is used in other areas where people do not listen to the radio, businesses should not expect the same effect. 【常见逻辑疑点：地点问题：提示词：local】
