The answer is B. The program prints:
Time to recharge!
This answer was checked by running the program for real.
Why?
Python checks the conditions from the top and runs the first one that is true. Is 5 > 10? No. Is 5 > 5? No. Neither was true, so the else part runs.
Trace table
A trace table follows the program step by step. Here’s this one:
| question | answer |
|---|---|
| battery > 10 | False |
| battery > 5 | False |
The code again
battery = 5
if battery > 10:
print("Full speed ahead!")
elif battery > 5:
print("Slow and steady.")
else:
print("Time to recharge!")Try it: change one number in the program and predict the new output before you run it.
