ase change in which old, atomistic, and impressionistic ways of doing research are superseded by a far more systematic and united methodology. To bring social sciences to the level of rigor already achieved by some of the physical sciences, a new type of facility will be needed. This will be a trans-disciplinary, Internet-based collaboratory that will provide social and behavioral scientists with the databases, software and hardware tools, and other resources to conduct worldwide research that integrates experimental, survey, geographic, and economic methodologies on a much larger scale than was possible previously. This facility will enable advanced research and professional education in economics, sociology, political science, social geography, and related fields.

In many branches of social sciences, a new emphasis on the rigor of formal laboratory experimentation has driven researchers to develop procedure and software to conduct online interaction experiment using computer terminals attached to local area networks. The opportunity to open these laboratories to the Internet will reduce the cost per research participant and increase greatly the number of institutions, researchers, students, and research participants who can take part. The scale of social sciences experimentation can increase by an order of magnitude or more, examining a much wider range of phenomena and ensuring great confidence in results through multiple replication of crucial studies.

Technology for administering questionnaires to very large numbers of respondents over the Internet will revolutionize survey research. Data from past questionnaire surveys can be the springboard for new surveys with vastly larger numbers of respondents at lower cost than by traditional methods. Integrated researches can combine modules using both questionnaire and experimental methods.Results can be linked via geographic analysis to other sources of data including census information, economic statistics, and data from other experiments and surveys. Longitudinal studies will conduct time-series comparisons across data sets to chart social and economic trends. Each new study will be designed so that the data automatically and instantly becomes part of the archives, and scientific publications will be linked to the data sets on which they are based so that the network becomes a universal knowledge system.

A "phase change" (Para. 1) is one in which

A．an old period ends and a new period begins.

B．a gradual invisible transition takes place.

C．fragments are united into a whole.

D．social sciences come to be united with physical sciences.

ounded by four blank walls and listening to the heartbeat of a _2__city outside my window. I felt very small. It was as if I had literally been __3__ into another world, and in a way I had: One day I had been at home in the suburban town where I’d lived for 18 years and knew everyone, and the next day I had moved into a tiny room in a huge city across the country where I didn’t know anyone. I had always thought there would be a neat __4__ between my previous self and my college self, but it turns out identity is more __5__ than that.

It was strange to feel my past life almost __6__ away as I entered this brand-new phase of my life. I didn’t know how to __7__ myself during my first couple of months at Penn because everything that defined me was back in California. I felt __8__ from my college friends because they only knew the college me. How could they really know me without knowing what Mission Boulevard looked like late at night with the Niles hills in the background？ How could they know me without knowing the friends who I had __9__ to Japan with or the friends I had gone to school with since kindergarten？ How could they know me if they hadn’t met my family？ How could they know me, or I them, if we didn’t know one another’s __10__ experiences？
