The answer of the question 5 /Module 4

I would like to understand the answer of the question 5 of the Module 4. Because the features “GarageArea” and “GarageCars” are positively correlated, the consequence of remove of “GarageArea”, if that is the reason, would give more weights to the feature “GarageCars” . But that isn’t the case, therefore the reason would be another one. Am I wrong ?

Thank you very much for this excellent course.
