Passage 4Our analysis therefore suggests that the real problem facing the black community lies in the educational obstacles prior to the Ph. D. programs rather than in the pour-in of foreign students. Equally, our analysis suggests that we ought to treat foreign students as an important source of brain gain for us and that we ought to facilitate, rather than hinder, their arrival and their entry into our work force. How could this be doneThere is a long-standing provision in our immigration laws under which those who bring in a certain amount of financial capital (which will "create jobs") are allowed to immigrate: A foreigner who invests one million dollars in a commercial enterprise established in a high-unemployment area, which creates jobs for at least ten Americans, is automatically given immigrant status (i.e., a green card). We suggest extending the idea from financial to human capital.Currently, graduate students who wish to stay on in the United States after their Ph. D. s must be sponsored by their employers, a process that imposes substantial hardship both on the students and on smaller employers.The standard procedure is in two stages. First, the U. S. Department of Labor must, on the basis of a U. S. employer’s sponsorship, certify that "no American can do this job." Then, the would-be immigrant must apply for immigrant status at the Immigration and Naturalization Service (INS). If all goes right, the entire process takes about two years (considerably more for citizens of certain countries). But things may not go right: there could be problems at either stage. Thus, the employer or the "alien" must hire an immigration lawyer. The current process, then, is costly both to the would-be immigrant and to the employer (and hence, it unfairly penalizes smaller firms that cannot afford this expensive process and so cannot recruit this foreign talent).The Immigration and Naturalization Act of 1990 introduced an alternative route for professors and researchers to secure immigrant status. Essentially, it eliminates the average processing time to about one year, it does not eliminate any of the uncertainty or the need for expensive legal counsel.We budget that automatic green cards be given to all those who obtain a Ph. D. in the science and engineering programs at our universities. In adopting such a "guaranteed green card" proposal, we would be recognizing the important contribution that these students make to our leading position in science by giving equal weight to human capital and financial capital. The author’s proposal differs from the Immigration and Naturalization Act of 1990 in（）

Passage 1The future of space exploration depends on many things. It depends on how technology evolves, how political forces shape competition and partnerships between nations, and how important the public feels space exploration is. The near future will see the continuation of human space flight in Earth’s orbit and unpiloted space flight within the solar system. Piloted space flight to other planets, or even back to the moon, still seems far away. Any flight to other solar systems is even more distant, but a huge advance in space technology could drive space exploration into realms currently explored only by science fiction.The 1968 film 2001: A Space Odyssey depicted commercial shuttles flying to and from a giant wheel-shaped space station in orbit around Earth, bases on the moon, and a piloted mission to Jupiter. The real space activities of 2001 will not match this cinematic vision, but the 21st century will see a continuation of efforts to transform humanity into a spacefaring species.Perhaps the most difficult problem space planners face is how to finance a vigorous program of piloted space exploration, in Earth’s orbit and beyond. In 1998 no single government or international enterprise had plans to send people back to the moon, much less to Mars. Such missions are unlikely to happen until the perceived value exceeds their cost.One belief shared by a number of space exploration experts is that future lunar and Martian expeditions should be aimed at creating permanent settlements. The residents of such outposts would have to "live off the land," obtaining such necessities as oxygen and water from the harsh environment. On the moon, pioneers could obtain oxygen by heating lunar soil. In 1998 the Lunar Prospector discovered evidence of significant deposits of ice, a valuable resource for settlers, mixed with soil at the lunar poles. On Mars, oxygen could be extracted from the atmosphere and water could come from buried deposits of ice.The future of piloted lunar and planetary exploration remains largely unknown. Most space exploration scientists believe that people will be on the moon and Mars by the middle of the 21st century, but how they get there, and the nature of their visits, is a subject of continuing debate. Clearly, key advances will need to be made in lowering the cost of getting people off Earth, the first step in any human voyage to other worlds. It is predicted that people who will live on other planets would have to（）
