The provided code for `drawSquare(size)` primarily demonstrates the use of **Iteration**. Here's a breakdown of the key concepts:

1. **Iteration**: The `FOR` loop iterates 4 times, allowing the drawing of the four sides of the square. Each iteration corresponds to one side of the square.

2. **Sequencing**: The instructions within the loop are executed in a specific sequential order for each iteration—first `forward(size)`, then `turnLeft(90)`.

3. **Selection**: There is no selection (such as `if` statements or conditionals) present in this code.

Thus, the main control structure represented in the code is **Iteration**. The code effectively describes a procedure to draw a square by repeating a set of instructions four times, which emphasizes the looping (iteration) aspect without any conditional branching.
