这是一篇关于青少年吸烟行为受电影明星影响的研究的完形填空。我们需要根据上下文语境和语法结构，从给定的词汇库中选择合适的单词填入空格。

以下是详细的推理过程：

• 第47题： 句子为“Teenagers aged 10 to 19 were ______ about their smoking habits and their attitudes toward smoking.”（10到19岁的青少年就他们的吸烟习惯和对吸烟的态度被______。）这里是一个被动语态结构，且后面接了“about”，结合选项，surveyed (调查) 最符合语境，表示“被调查”。
• 第48题： 句子为“These were scored on a five-point ______.”（这些在五点________上进行了打分。）“five-point scale”（五点量表）是常见的表达，用于衡量态度或程度。因此选择 scale (量表)。
• 第49题： 句子为“Altogether, 632 students from five rural New England schools ______.”（总共，来自五所新英格兰农村学校的632名学生______。）这里需要一个动词来描述这些学生在研究中的行为，participated (参与) 最为合适，表示他们参与了这项调查。
• 第50题： 句子为“Teens whose favorite stars smoked in films were more likely to score ______ than teens who chose stars who did not smoke.”（最喜欢的明星在电影中吸烟的青少年比那些选择不吸烟明星的青少年更可能得________分。）根据上下文，受吸烟明星影响的青少年对吸烟的态度更积极，因此得分会更高。选择 higher (更高的)。
• 第51题： 句子为“And the more a star portrayed (描绘) smoking, the more ______ the adolescent (青少年) viewed smoking.”（明星描绘吸烟的次数越多，青少年看待吸烟就越______。）这里需要一个副词来修饰“viewed”，表达积极的态度。favorably (有利地，赞许地) 符合语境。
• 第52题： 句子为“Teens whose favorite stars smoked in two films were 1.5 times more likely to score on the ______ end of the scale...”（最喜欢的明星在两部影片中吸烟的青少年得分在量表________端的可能性是1.5倍...）结合前面的“higher score”，这里指的是量表的“上端”，即高分端。选择 upper (上面的)。
• 第53题： 句子为“...than those who chose '______' stars.”（...比那些选择“______”明星的人。）这里需要一个形容词来修饰“stars”，并与前面提到的吸烟明星形成对比。选择 non-smoking (不吸烟的)。
• 第54题： 句子为“Stars who smoke may therefore ______ teens to try out smoking...”（因此，吸烟的明星可能会________青少年尝试吸烟...）这里需要一个动词，表示“鼓励”或“促使”。encourage (鼓励) 符合语境。
• 第55题： 句子为“...suggest the authors, who conclude: 'We believe this ______ strongly suggests that...’”（...作者们总结道：“我们相信这个________强烈表明...”）这里需要一个名词，指代前面的研究结果。evidence (证据) 最为合适。
• 第56题： 句子为“...media descriptions of tobacco use by popular movie stars ______ to adolescent smoking.'”（...流行电影明星对烟草使用的媒体描述________青少年的吸烟行为。）这里需要一个动词，表示“促成”或“导致”。contribute (促成，有助于) 符合语境，构成“contribute to”短语。
