SelectionIterationSequencing

Answer 1

witch one

Answer 2

The code you provided primarily illustrates **iteration**. Let's break it down according to the three fundamental programming constructs you mentioned: selection, iteration, and sequencing.

1. **Sequencing**: This refers to the execution of statements in the order they appear. In your code, the `PRINT` statement that outputs "The rainbow colours are: " is executed before the loop starts, so you have sequencing in play.

2. **Iteration**: The loop (`FOR colour in colourList:`) demonstrates iteration. This loop goes through each item in the `colourList` array and executes the `PRINT colour` statement for each color in the list.

3. **Selection**: There is no selection construct in your code. Selection typically involves conditional statements (like `if` statements) that allow for different paths of execution based on certain conditions.

So, while your code includes sequencing and iteration, it does not involve selection.

In summary:
- The constructs used in your code are **iteration** (the `FOR` loop) and **sequencing** (the order of operations). Selection is not present in this code.

Answer 3

In your code snippet, the main programming construct being used is **iteration**.

The `FOR` loop iterates over each element in the `colourList` array and performs the action of printing each color. So, to clarify:

- **Iteration**: The `FOR` loop that goes through each color in `colourList`.
- **Sequencing**: The order of execution, starting with the `PRINT` statement before the loop and then executing the loop.
- **Selection**: Not used in this code.

Thus, if you are looking for which specific construct is most prominently featured, the answer is **iteration**.
