Answer:
strong, long duration winds in a large fetch weak
Explanation:
A fetch is an area of the ocean or sea where wind blows in a fixed direction, this consistent wind leads to waves.
Fetch length is the distance reached by the wave generating winds when measured in from a horizontal direction. The wind creates wave by forming a drag and a frictional drag, the wind the flow over the wave making it grow. Therefore, a strong, long duration winds in a moderate fetch or weak fetch will produce largest waves.
The air behind the front is cooler than the air it is replacing and the warm air is forced to rise, so it cools. As the cooler air cannot hold as much moisture as warm air, clouds form and rain occurs.
Endemic diseases result in a decreasing population, so with that said you can rule out choices B and D.
Among the two left, letter A is the most appropriate answer. Not all endemic diseases have an effect on the number of children a population will have. So if we are speaking about endemic diseases in general, the answer is:
A. Endemic diseases can result in decreasing population numbers: many people die form diseases, and others move away from or avoid moving to places where diseases are rampant.
