Final answer:
Ella's generalization can be tested by breaking a 4s fact into two 2s facts. This can be done using a specific example.
Step-by-step explanation:
In order to test Ella's generalization, we can choose a 4s fact and break it into two 2s facts. Let's take the example of 4 x 3 = 12. We can break it into two 2s facts: 2 x 3 = 6 and 2 x 3 = 6.
So, Ella's generalization holds true in this case, as breaking the 4s fact into two 2s facts gives us the correct answer.
