Consider the following code:

EXIT_STRATEGY = "Run!"
PROMPT_TEXT = "Would you like to continue? You could run... "
DANCE = 'Renegade'

response = input(PROMPT_TEXT)

what_i_do = DANCE

while response != EXIT_STRATEGY:
what_i_do += DANCE
print(f'Ok... I do {what_i_do}!!!')
response = input(PROMPT_TEXT)

print(DANCE)

What is the sentinal variable? Be sure to use include capitals and spaces where appropriate.

Question

Consider the following code:

while response != EXIT_STRATEGY:
    what_i_do += DANCE
    print(f'Ok... I do {what_i_do}!!!')
    response = input(PROMPT_TEXT)
    
print(DANCE)

What is the sentinal variable? Be sure to use include capitals and spaces where appropriate.

The question asks to identify the sentinel variable in the given code and to use the exact spelling with capitals and spaces where appropriate.
First, note the assignment at the top: EXIT_STRATEGY = "Run!". This line defines a variable whose value is the string that will be used to signal termination of the loop.
Next, examine the loop condition: while response != EXIT_STRATEGY:. The loop continues to execute as long as the user’s input (response) does not match the value stored in EXIT_STRATEGY. Therefore, EXIT_STRATEGY is the sentinel variable that, when matched, ends the loop.
Additionally, the final print after the loop uses print(DANCE), which would run only after the loop exits, confirming that the loop termination depends on a match to EXIT_STRATEGY.
Regarding the formatting detail in the provided answer list: the correct sentinel variable name is EXIT_STRATEGY with capitals and an underscore, exactly as defined in the code. If an answer shows a leading space (" EXIT_STRATEGY"), that is likely a formatting error in the prompt data rather than a different variable name; the intended sentinel remains EXIT_STRATEGY.
There are no answer options given in this prompt (the answer_options array is empty). When a question asks for a specific identifier like this, the expected response is the exact variable name, i.e., EXIT_STRATEGY, not a description of its value.
In summary, the sentinel variable controlling loop termination is EXIT_STRATEGY, whose value is the string "Run!" that the program compares against user input to decide when to stop looping.
