Answer to Problem 1RQ

Correct answer: The land is the original part of the bore left after rifling grooves are formed.

Explanation of Solution

A barrel of a gun is a steel bar that is carved out due to drilling. Each barrel is unique in its inner surface due to the drill marks. The barrel also has an extra step known as rifling where spiral grooves impress the inner surface. There are several raised regions inside the rifled groove which are called as lands.
