Read the following passage and answer the question.

Read the following passage and answer the question.

Disequilibrium at the interface of water and air is a factor on which the transfer of heat and water vapor from the ocean to the air depends. The air within about a millimeter of the water is almost saturated with water vapor and the temperature of the air is close to that of the surface water. Irrespective of how small these differences might be, they are crucial, and the disequilibrium is maintained by air near the surface mixing with air higher up, which is typically appreciably cooler and lower in water vapor content. The turbulence, which takes its energy from the wind mixes the air. As the speed of wind increases, so does the turbulence, and consequently the rate of heat and moisture transfer. We can arrive at a detailed understanding of this phenomenon after further study. The transfer of momentum from wind to water, which occurs when waves are formed is an interacting-and complicated phenomenon. When waves are made by the wind, it transfers important amounts of energy-energy, which is consequently not available for the production of turbulence.

This passage principally intends to:
A . resolve a controversy
B . attempt a description of a phenomenon
C . sketch a theory
D . reinforce certain research findings
E . tabulate various observations

Answer: B

Explanation:

The answer is “attempt a description of a phenomenon”, because in the passage they author starts to describe what a phenomenon.
