Final answer:
The provided line of script is a conditional statement written in a programming language. It checks if the stop light is green and there are no pedestrians, and displays corresponding messages.
Step-by-step explanation:
This line of script is written in a programming language, which falls under the subject of Computers and Technology. In programming, the provided code is a conditional statement that checks two conditions using the logical operator '&&' (logical AND). If both conditions are true, it will execute the code inside the curly brackets after the 'if' statement; otherwise, it will execute the code inside the curly brackets after the 'else' statement.
In this case, the condition checks whether the variable 'stopLight' is equal to the string 'green' and the variable 'pedestrians' is equal to false. If both conditions are true, the message 'Go!' will be displayed. If either one or both conditions are false, the message 'Stop' will be displayed.
