To answer this question, we need to understand the meaning behind the gesture made by the bus driver in Bolivia.
The correct answer is:
C) It's full
Explanation:
The so-so gesture, which involves twisting the flat, open hand, is a common gesture used by bus drivers in Bolivia to indicate that the bus is full. It means that there is no more space available for additional passengers. Therefore, the correct interpretation of the gesture is that the bus is already at maximum capacity and cannot accommodate any more passengers.
