Broken ride<br>Allie went to the local fair. She went on the first ride she saw. She thought it would be safe. But all of the sudden the brakes failed. Allie ended up falling out.
Allie's expectations of ride safety remained unchanged after the brakes failed. 
It is not expressed definitively by the context that Allie no longer expected rides to be safe after the brakes on her ride failed, though it can surely be inferred. Therefore, the statement might be true or might not be. The system may have been thrown off by the wording.
