Question: Read the following paragraph carefully and answer the question that follows:
The size of oceanic waves is a function of the velocity of the wind and of fetch, the length of the surface of the water subject to those winds. The average impact of waves against a coastline is a function of the size of the waves and the shape of the sea bottom. The degree of erosion on coastline is a function of the average impact of waves and the geologic composition of the coastline.
According to the above paragraph, which of the following options will be true?
The last sentence states that, “The degree of erosion on coastline is a function of the average impact of waves…” The sentence prior to that tells us that, “The average impact of waves against a coastline is a function of … the shape of the sea bottom”. From these two sentences, it can be concluded that the degree of erosion on coastline is related to the shape of the sea-bottom.
