To determine which tables list all the different ways Harry can get to Hogwarts and back, we first need to understand the options he has for traveling to and from Hogwarts. Harry has three modes of transportation:

  1. Hogwarts Express
  2. Flying Car
  3. Knight Bus

To find all the combinations of travel to and from Hogwarts, we can treat the trips as pairs of choices.

  • For "To Hogwarts", Harry can choose any of the three options:

    • Knight Bus
    • Flying Car
    • Hogwarts Express

  • For "From Hogwarts", Harry also has the same three options available.

We can generate all combinations by taking each option for the trip to Hogwarts and pairing it with each option for the return trip:

  1. Knight Bus → Knight Bus
  2. Knight Bus → Flying Car
  3. Knight Bus → Hogwarts Express
  4. Flying Car → Knight Bus
  5. Flying Car → Flying Car
  6. Flying Car → Hogwarts Express
  7. Hogwarts Express → Knight Bus
  8. Hogwarts Express → Flying Car
  9. Hogwarts Express → Hogwarts Express

Now, let's list these combinations clearly (each represents a unique way to travel to and from Hogwarts):

  • (Knight Bus, Knight Bus)
  • (Knight Bus, Flying Car)
  • (Knight Bus, Hogwarts Express)
  • (Flying Car, Knight Bus)
  • (Flying Car, Flying Car)
  • (Flying Car, Hogwarts Express)
  • (Hogwarts Express, Knight Bus)
  • (Hogwarts Express, Flying Car)
  • (Hogwarts Express, Hogwarts Express)

Now, let's evaluate the tables provided:

Table A:

  • Knight Bus, Knight Bus
  • Knight Bus, Flying Car
  • Knight Bus, Hogwarts Express
  • Flying Car, Knight Bus
  • Flying Car, Flying Car
  • Flying Car, Hogwarts Express
  • Hogwarts Express, Knight Bus
  • Hogwarts Express, Flying Car
  • Hogwarts Express, Hogwarts Express

Table B:

  • Knight Bus, Hogwarts Express
  • Flying Car, Flying Car
  • Hogwarts Express, Knight Bus
  • Knight Bus, Knight Bus
  • Flying Car, Hogwarts Express
  • Hogwarts Express, Flying Car
  • Knight Bus, Flying Car
  • Flying Car, Knight Bus
  • Hogwarts Express, Hogwarts Express

Analysis:

  • Table A includes all possible combinations listed above.
  • Table B does not include all combinations and contains some incorrect pairings.

Conclusion: The correct answer is:

  • Choice A: Table A (because it lists all the different ways Harry can get to Hogwarts and back).
    Table B does not represent all combinations.
