- 1: true, true - 2: true, false - 3: false, true - 4: false, false

##### Answer: 3 Symbol follows below conventions, 1. Every symbol value returned from Symbol() is unique irrespective of the optional string. 2. Symbol.for() function creates a symbol in a global symbol registry list. But it doesn't necessarily create a new symbol on every call, it checks first if a symbol with the given key is already present in the registry and returns the symbol if it is found. Otherwise a new symbol created in the registry. Note: The symbol description is just useful for debugging purposes.
