Answer:

a. SAR is the Sodium adsorption ratio of the water used for irrigation purpose. SAR is ratio of sodium concentration to that of calcium and magnesium concentration.This value is also useful while managing soils that have high concentration of sodium which can occur naturally in some soils.  Although sodium is a macro-nutrient for plants, higher concentration of sodium can cause the displacement of the calcium and magnesium ions in soil which can affect the soil structure by preventing aggregation of clay in the soil resulting in a decrease in the infiltration rates.

b. EC is the electrical conductivity of the soil which depends on the salinity of the soil. High salinity means more solutes in water and this increases the osmotic potential of the soil solution making it difficult for plants to absorb water.

Answer:

D) The Agency Problem

Explanation:

The agency problem refers to a conflict of interests between the principal and his/her agent. Agents have a fiduciary duty to act on the best interest of their principal, but sometimes agents place their own personal interest before the interests of their principal.

in this case, the brokers should act on behalf of their clients to make them earn the largest possible profits, but instead they focus on convincing them about transactions that increased the broker's profit and not the clients'.
