Logical Deduction - Functional Relations
XAT 2018 · Verbal Ability & Logical Reasoning · Easy · Critical Reasoning
Read the following paragraph 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?
- A.
The fetch of wind is related to the shape of the sea bottom.
- B.
The size of oceanic waves will not fluctuate far from average.
- C.
The size of oceanic wave is correlated with the shape of the sea bottom.
- D.
Degree of erosion on coastline is not related with the velocity of wind.
- E.
Degree of erosion on coastline is related to shape of the sea-bottom.
E
Explanation
Erosion = f(impact, geology). Impact = f(wave size, sea-bottom shape). Therefore, erosion is functionally related to the shape of the sea bottom.
