I still do n't know what was causing the massive failure because I saw no wrecked cars . I can only assume the cluster arose from several semi trucks all huddled together . Once we made it past that , we still had to drive to the exit and park .
What kind of failure happened ?
Pick the best answer from the following options:
A. The " truck sale " on the semi 's ahead was very popular and we missed getting in line .
B. The drive in movie was late
C. Traffic was blocked .
D. The free turkey giveaway was postponed .
