Large waves cause erosion of shorelines. Seawalls constructed of concrete can protect shorelines from this erosion. Which type of connection is made between the ideas in these sentences?

Answer 1

The connection between the ideas in these sentences is a cause-and-effect relationship. The first sentence describes the cause (large waves causing erosion of shorelines), while the second sentence presents a solution or effect (the construction of concrete seawalls to protect shorelines from that erosion). Essentially, the erosion of shorelines prompts the need for seawalls as a protective measure.
