  Explanation/Reference:

  The code snippet that you have sent is a while loop with an if statement and a print statement inside it. The code is as follows:

  while True: if counter < 0: print("") else: print("**") The code starts with entering a while loop that repeats indefinitely, because the condition "True" is always true. Inside the loop, the code checks if the value of "counter" is less than 0. If yes, it

  prints a single asterisk () to the screen. If no, it prints three asterisks (**) to the screen. However, the code does not change the value of "counter" inside the loop, so the same condition is checked over and over again. The loop never ends,

  and the code enters an infinite loop.

  The program outputs either one asterisk () or three asterisks (**) to the screen repeatedly, depending on the initial value of "counter". Therefore, the correct answer is D. The program enters an infinite loop.

  Insert the code boxes in the correct positions in order to build a line of code which asks the user for a float value and assigns it to the mass variable. (Note: some code boxes will not be used.)

  Select and Place:

  Explanation/Reference:

  One possible way to insert the code boxes in the correct positions in order to build a line of code that asks the user for a float value and assigns it to the mass variable is:

  mass = float(input("Enter the mass: "))

  This line of code uses the input function to prompt the user for a string value, and then uses the float function to convert that string value into a floating-point number. The result is then assigned to the variable mass.

  You can find more information about the input and float functions in Python in the following references:

  A. A
