A student is writing a research paper on the history of irrigation in the United States, situating the development of Hume Lake (created in Fresno County, California, in 1908) in a larger historical context. The student claims that California's climate renders irrigation an essential component of agriculture in some parts of the state but not in others.
Which quotation from a study of California agriculture best supports the student's claim?
"The usefulness of irrigation infrastructure in California today cannot be overstated, since it is the most common means of conveying water for agricultural purposes."
A
"Natural humidity, which renders irrigation unnecessary or reduces its importance in the northern reaches of California, gradually decreases toward the sun-scorched but nonetheless fertile valleys of the southern part of the state."
B
"Sprinkler irrigation systems are a contemporary way of irrigating that requires machinery to spray water in all directions. These are currently used throughout the United States and are especially prevalent in California."
C
"The irrigation system developed by the Hohokam people in the 7th century CE in what is now Arizona was simple, but this system applied hydraulic engineering design features that are in use today throughout California."
