Answer:
great increases in agricultural productivity
Explanation:
The goal and aim of the drip irrigation method is to cut the volume of water used for irrigation. Usually, normal irrigation involves channeling water into a field in order to provide another option for limited water regime in an area. This procedure wastes water a lot and can cause fertilizers to reach ground water systems. Sometimes, if not correctly applied, they can wash nutrients away from the soil into nearby water bodies.
Israel developed a drip water system which directly applies water in form of drips to farm crops instead of flooding the whole field. This will help to save more water and prevent ground water pollution. Adoption of this method has led a spike in Israel's agricultural productivity and more water has been conserved for other use.

Answer:
Option (C)
Explanation:
The continental drift theory was introduced by Alfred Wegener. He said that the continents moved over the vast ocean surface from one place to another.
He contributed many pieces of evidences in support f this theory, which includes the founding of similar fossil assemblages, similar rocks types in the distant continents, matching of the continental boundaries, but he was not able to explain the main mechanism behind the continental motion.
Due to this, this theory was not accepted by the other scientists and he was criticized by them.
Later, this theory was modified into the Plate tectonic theory which was successful in explaining the mechanism behind the continental motion i.e the formation of convection current in mantle that drives the plates movement.
Thus, the correct answer is option (C).
