11月21日北美，竟然遇到Prep test 2的原题，

Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.



问题和prep不同，问的是哪个选项strengthen。选项具体是什么记不清了。。
