Question

A cavity wall is a wall that consists of _________ leaves.

(a) Only one leaf

(b) Two

(c) Four

(d) Zero

This question was addressed to me in my homework.

My enquiry is from Types of Walls in chapter Load Bearing Walls of Construction & Building Materials

Answer 1

The correct choice is (b) Two

For explanation I would say: A cavity wall is that type of load-bearing wall which consists of two leaves. These leaves are made up of structural units and are separated by a cavity which is why these are called cavity walls.
