Final answer:
Henry does understand what Sheldon meant about 'fixing it,' which implies addressing deeper issues in family dynamics and reliance on technology, not just mechanical problems.
Step-by-step explanation:
The passage suggests that Henry does understand what Sheldon meant about "fixing it." When Sheldon refers to fixing something, he likely means addressing a deeper issue or problem beyond just mechanical or practical aspects. The conversation involving parents and the dynamic in their home with their children points towards the necessity of a fundamental change in their interactions and reliance on technology. In the context of these passages, it seems that Henry grasps the implications of Sheldon's statement that they need to start anew and recalibrate their family life without the overreliance on the automated house and machinery that has taken over the roles of parenting to some extent.
