Which of the following statements describes one of the cons of the simple anchors?

The statement that identifies the con of simple anchors is that they can lack redundancy. In rope rescue scenarios, redundancy is a critical safety feature, which means having additional systems in place so that if one system fails, there is another in place to prevent failure. A simple anchor typically consists of a single point of attachment without any backup, which poses a greater risk in environments where forces can be unpredictable.

For example, if a simple anchor were to fail due to wear, improper placement, or an unexpected load, the entire setup could collapse. Greater risks are inherent when using anchors that do not have a secondary means of securing the load. Therefore, in high-stakes situations such as rescues, redundancy becomes essential for the safety of both the rescuer and the subject.

In contrast, complex knots can provide secure configurations and may offer alternatives to redundancy but can also offer complexities that require a higher skill level to execute effectively. Multiple carabiners, while potentially beneficial for added capabilities, are not a standard requirement for simple anchors, and while securing to the ground may not be needed in every scenario, it does not specifically relate to the deficiencies of a simple anchor itself. Thus, the issue of redundancy stands out as a significant drawback.
