问题 The purpose of the simulation is to estimate mean vehicle queue lengths and delays for various vehicle ______and train frequencies.
选项 A、popularity
B、densities
C、intensities
D、prosperity
答案 B
解析 逻辑关系题：并列。所填词与frequencies形成结构和语义上的并列关系，并表示vehicle queue lengths and delays的原因，因此答案选[B]densities“密集，密度”。[A]popularity“流行，普及”；[C]intensities“强度，剧烈”；[D]prosperity“繁荣，昌盛”。
