Question - Vectors Representation Exercise

The image seems to display graphical representation of vector addition and subtraction. However, without the context of the problem such as specific questions or instructions related with the vectors, no unique solution can be provided.

The first box possibly shows two vectors being added head-to-tail.

The second box might be showing vector subtraction by adding the negative of a vector.

The third box possibly represents two equal vectors pointing in opposite directions, suggesting that their sum is zero.

In the fourth box, it could be an example of the Parallelogram rule for vector addition.
