1. We {1:SA:%100%'ve been#Correct~*#Incorrect} (be) here {2:SA:%100%for#Correct~*#Incorrect} several hours.
2. She {3:SA:%100%'s driven#Correct~*#Incorrect} (drive) the same car {4:SA:%100%for#Correct~*#Incorrect} fifteen years.
When students answer the quiz as below, moodle says it's incorrect.
1. We've been here for several hours.
