Which activities allow for iteration through an array of strings?

The choice of "For Each and While" is correct because both of these activities are designed to allow iteration through collections, including arrays of strings.

The "For Each" activity specifically is used to iterate over each item in a collection, making it ideal for processing each string in an array one at a time. It simplifies the loop structure by automatically handling the iteration index and is particularly suited for cases where the number of iterations is directly tied to the number of elements in the array.

The "While" activity allows for repeated execution of a block of code as long as a specified condition remains true. This can also be used to iterate through arrays, although it requires the developer to manage the index manually. This gives flexibility in controlling the loop, allowing for various conditions to determine when to stop iterating.

In contrast, other options include activities that do not serve the primary purpose of iterating through a collection. For instance, "For and Repeat Until" generally imply certain fixed conditions and aren't as straightforward for handling each element in a collection as "For Each" is. Similarly, "Do While and Break" can create looping structures but are not inherently built for the purpose of iterating over arrays of strings without additional conditional checks.

Lastly, "Switch and
