There are the traditional means to advertise: newspapers, magazines, radio, television, billboards, and even taxicabs. Yet there are other types of advertising, such as aerial advertising (空中广告), which is very different in many aspects.Radio advertising is aimed at the local customers. The downside of using radio is that the customer needs to have the station tuned in. Placement of ads on the radio is another consideration since listening time is important to the ads. The upside of using radio is that the audience does tend to remember jingles (广告词) that are easy to remember.Magazine and newspaper advertising is directed to the subscribers (订阅人). The subscriptions limit the availability to nonsubscribers. The concept of being able to read information online is slowly changing the subscriptions to this advertising market. Limitations of circulation of magazines and newspapers mean fewer people viewing the advertisements.Television advertising is channeled to the viewers. Limitations of viewers based on the available channel selections lower the exposure audience. With the availability of satellite to consumers, locating the client base for advertisement can easily be lost or overlooked.Billboard advertising focuses on the area of the billboard. Limitations of outside regions viewing the information are high. Getting the attention of the passersby to view the information is also a subject to be considered.Aerial banner advertising focuses on vast population of various regions. Based upon the region, the exposure is limitless. Grabbing or gaining the publics attention is based on simple human nature to look up at the airplane that is flying overhead. People typically look up when a plane flies overhead. To have a banner with an advertisement adds more curiosity and response.People tend to remember aerial advertising at a high rate. They also tend to communicate to others about the advertisement by sharing the information by word of mouth. This word of mouth is absolutely free but is of important benefit to aerial advertising. Aerial advertising can be done throughout the entire year, but the warmer months are preferred. Aerial advertising has certain restrictions, yet these restrictions are fewer than the other means of advertising.1The underlined word “downside” in the second paragraph can be replaced by “_”AstrengthBweaknessCpurpose Dinstruction解析：选B词义猜测题。依据第二段内容推断，downside和upside相呼应，分别指收音机广告的弊端和优势。故B项正确。2Which of the following is the author probably in favor of?ARadio advertising.
