问题     A close analogy to a study design is the rough sketch made by an artist before he commits his vision to canvas(画布). The broad outlines are drawn, the proper perspective achieved, and the total impact of the picture-to-be can be partially appreciated in advance. So it is with the design of research: it specifies in advance the kinds of statements that can be made on the basis of its findings and fixes the perspectives against which these findings are to be evaluated.
    One major purpose of this study was to demonstrate whether or not the newer social research techniques could help in broadening and deepening knowledge concerning juvenile delinquency(少年犯罪). Construction of the design was guided by this goal of exploring new methods in the analysis of juvenile delinquency. However, research technique developed in one content area can not be mechanically transferred to another. A new application of them requires substantial changes and it is these innovative modifications which this study offers as its contribution.
    Juvenile delinquency has been the subject of many previous studies using a variety of research techniques. This study makes an additional contribution by using a design specially planned to permit a comparison of several approaches.
    The drawing up of the study design profited greatly from an extensive survey of previous re searches on crime, undertaken during the earliest stage of the project. It was found that most studies could be classified as belonging to one or more of three broadly conceived types: social background study, family background study and personal motivation study.
    Each type has its characteristic design and mode of interpretation and each has produced information of considerable importance. Yet not attempt was made in any of ’the studies to integrate one or more of these three design types. It became apparent that one of the major contributions a pilot study could make to both method and substantive findings would be to bring all three study types together in one design for the purpose of correlating(使相互关联) their findings and evaluating their relative importance in producing data of use to the practitioner.
The major contribution of this study is to _______.
选项 A、develop a new research technique easily transferred from one area to another
B、make a comprehensive analysis of juvenile delinquency
C、demonstrate the successful application of new research techniques in a new area
D、modify creatively the previous research finding of juvenile delinquency
答案C
解析 推理判断题。题干中的关键词是contribution，该词在第二段末尾出现。根据第二段最后一句可知，the contribution of this study是指these innovative modifications，these innovative modifications又是指substantial changes，而A new application of them需要这些changes。them是指上文提到的the newer social research techniques、new methods。作者在这里肯定了本段首句中的One major purpose of this study将会得以实现，也就是说他所做的这些创新的、实质性的变化意味着the newer research techniques在juvenile delinquency这一新领域中的应用could help。因此，选项C正是此项研究的contribution。
