The question asks for the finished elevation difference between two specified lots, where one lot is explicitly stated to be 4 feet, 6 inches higher than the other. When interpreting the measurements, the completed difference is directly provided: it is the height difference that defines how much higher one lot is than the other.

In this case, choosing the answer indicating that Lot 442 is 4 feet, 6 inches higher accurately reflects the given information. The measurement is a straightforward representation of the elevation difference, confirming that Lot 442 is indeed higher by that amount. Understanding the significance of elevation in excavation and grading practices is crucial, as it helps ensure proper drainage, accessibility, and structural integrity.

It’s important to remember that the other answers either state an incorrect elevation difference, suggest both lots are at the same level, or misidentify which lot is higher, which does not match the data presented in the question. Thus, reinforcing knowledge of precise measurements is essential for effective grading and excavation work.
