Multiple Choice

Let $A$ be the set of the following cities: $A = \{ \text { Arm, } M I \text {; Bone, } I D ; \text { Cheek, TX; Doublehead, } A L ; \text { Flbow Lake, } M N \}$ Suppose that these cities are connected by direct airplane service as shown in the figure below. Write a set of ordered pairs that show the direct connections between two cities. For example, $( A , E )$ means a direct connection from Arm to Elbow. Identify the correct set of these ordered pairs, and answer whether this set is a function? (Use $A$ to denote $\text { Arm }$ $B$ to denote $\text { Bone, }$ and so on.)
