As you did not provide options here I managed to find your question and the answer would be that the prices can be easily set by the government is definitely not an advantage of a price-based system. 
There are two ways the prices are set in the economic system:
1. They can be set by the government or
2. They can be freely set by the laws of supply and demand. 
        
                    
             
        
        
        
This would be known as a socialist system. 
Socialism is a political and economic theory that focuses on government control. In a socialist country, the government would control what businesses make, how much product they make, and what resources/services citizens will receive. In this system, their is very little room for individual freedoms or choices. This is due to the fact that the government controls a significant part of the economy.
