Multiple Choice

Read the following scenario and answer the question below.
Glass Lake, located in a valley in low forested mountains, for many decades of the 19th and early 20th centuries was a favorite picnic, recreation, and fishing site for people in surrounding towns and farms. However, in the middle of the 20th century, a trend began in which the privately-owned farms in the Lakeʹs watershed were purchased by large agribusinesses.
The decision was made to grow a profitable crop. The demand for quality farmland resulted in the sale of most of the family-owned establishments and a large increase in the area of land under cultivation. Most of the forests were cut to acquire the land needed for crops. The use of chemical fertilizers and pesticides increased several fold by the end of the century. In addition, the combined population of the lakeside villages quadrupled during the same time. The lake experienced a slow degradation of water quality and biodiversity. Sport fishing declined and the lake became murky while the sediments in the lake increased in depth.
-The murkiness (turbidity) of the water was analyzed and found to have several major sources, including .

A) algae, increased microscopic animal life, and pesticides
B) fertilizer particles, wind-borne atmospheric particles and wastewater discharge
C) pesticides, atmospheric deposition and wastewater discharges
D) erosion from the deforested hillsides, sediments produced from poorly treated wastewater discharge, and sediments produced from the increased plant biomass of the lake
E) erosion from the hillsides, solid nitrogen and phosphorus from agricultural fertilizers and numerous microscopic animals living in bottom sediments
