Question

A. true
b. false: a one-dimensional array can only store elements of a single data type, but a two-dimensional array can hold data of two different data types.

Answer 1

The answer to this question would be false. Both one and two dimensional arrays can only hold data of a single data type. For example, a two dimensional array would never be able to contain some data of type int and some data of type String.

I hope this helps.
