黄色線のところについてですが、between 複数名詞となっていますがどう訳せば良いんですか?between の後についている名詞が1つしかないので分かりません。どことどこの間ですか?

[Review] redt toda lira olqooq u obat A few years ago, a large American university had a new campus built, where each building was designed with consideration for such aspects as access, environmental impact, and use of advanced information and communication technology. However, at an early stage of the design of the campus, it was pointed out that no plans had been made for pathways or other routes between the new buildings. Such routes often present problems to architects, as the way people will walk between buildings is hard to predict before construction. The university president, who had taken personal charge of the project, said, "Just plant grass; don't make any pathways." The other members of the project committee were astonished at this instruction, but since the president had a reputation for vision in design and development, the committee agreed to construct no pathways but only to plant grass on the campus. One year after the completion of the new campus, the university president called for the committee to meet and inspect the development. Over the grassy lawns between the buildings, tracks had been clearly made by students and faculty walking from one place to another. "There!" said the president, pointing to the trackways, "Put the pathways there, where the tracks have already been made."
