StormRider was a simulator ride at Tokyo DisneySea. It simulated going into a weather storm in a futuristic airplane (a "StormRider") to dissipate the storm. The attraction opened on September 4, 2001, in the Port Discovery land of Tokyo DisneySea. The attraction closed on May 17, 2016 and replaced by a new Finding Nemo/Finding Dory simulator ride called Nemo & Friends SeaRider.
Someone going to Tokyo DisneySea could not ride of StormRider and Nemo & Friends SeaRider on the same day.  
The statement is definitely correct because the context states that the StormRider attraction closed and was replaced by the Nemo and Friends SeaRider attraction.  If the SeaRider attraction "replaced" the StormRider attraction that had closed than the two could not have been in operation at the same time and therefore a visitor to Tokyo DisneySea could not have gone on both attractions.  I think it was difficult for the system because it did not understand the word "replaced."
