We can learn from the passage that ______.

参考解析：

细节理解题。根据第一段中的“Students can earn both a Bachelor of Science (B.S.) and a Doctor of Philosophy Degree (Ph.D.) in approximately 6 years.”可知，在大约6年的时间里，学生可以同时获得理学学士学位和哲学博士学位，B项正确。根据第二段“Applicants to the Honors Program in Biochemistry & Molecular Biology must be in their last year of high school.”可知，申请人必须是高三的学生，A项中的“Grade one”错误；根据第三段第一句“Undergraduates will have the opportunity to work with top-level research scientists”可知，应该是本科生有机会和顶尖的研究科学家一起工作，而不是C项中的graduates；根据第三段第三句“By spring of their junior year, students will prepare an undergraduate thesis as preparation for their entry into graduate school.”可知，论文是需要的，D项中的not necessary错误。故选B。
