Question 1 · Foundations of Agricultural Education
Answer: B. Smith-Hughes Act of 1917
The Smith-Hughes Act of 1917 provided federal money for vocational agriculture, home economics, and trade instruction below the college level, which launched high school agriculture programs. The Smith-Lever Act created the Cooperative Extension Service, the Hatch Act funded agricultural experiment stations, and the Morrill Act established land-grant colleges, so all three deal with higher education, research, or outreach rather than secondary classrooms.
Question 2 · Agribusiness and Economics
| Item | Value |
|---|---|
| Variable (operating) costs | $220 |
| Fixed (ownership) costs | $80 |
| Expected yield | 40 cwt |
Answer: D. $7.50
Break-even price equals total cost divided by expected yield: ($220 + $80) ÷ 40 cwt = $300 ÷ 40 = $7.50 per cwt. The $5.50 figure covers only the variable costs (220 ÷ 40), and $2.00 covers only the fixed costs (80 ÷ 40). Subtracting fixed from variable costs before dividing gives the $3.50 figure.
Question 3 · Plant and Soil Science
Answer: D. Private applicator license
A private applicator uses restricted-use or state-limited-use pesticides to produce an agricultural commodity on land the applicator owns or rents. A commercial applicator applies these products to other people's property for hire, and a noncommercial applicator is someone, such as a government or institutional employee, who fits neither of those categories. A dealer license authorizes selling these products, not applying them.
Question 4 · Agricultural Mechanics, Engineering, and Technology
Answer: B. 50 lb
The effort arm is 60 − 6 = 54 inches and the resistance arm is 6 inches, so the mechanical advantage is 54 ÷ 6 = 9 and the effort is 450 ÷ 9 = 50 lb. The 45 lb figure comes from treating the whole 60-inch bar as the effort arm, and 75 lb comes from dividing the load by the 6-inch resistance arm. Multiplying the load by the mechanical advantage gives 4,050 lb, which is the opposite of what a lever does for the operator.
Question 5 · Natural Resources and Environmental Science
Answer: A. Grassed waterway
A grassed waterway is a shaped channel seeded to permanent sod that carries concentrated runoff off a field without cutting a gully. Contour strip cropping slows sheet and rill erosion across the slope but does not armor a channel where water concentrates. A riparian buffer protects a streambank at the field edge, and a windbreak addresses wind erosion.
Question 6 · Foundations of Agricultural Education
Answer: B. National Agricultural Statistics Service
The National Agricultural Statistics Service surveys producers and publishes acreage, yield, and production estimates down to the county level, along with the Census of Agriculture. The Economic Research Service analyzes economic trends using such data, the Natural Resources Conservation Service provides soil and conservation assistance, and the Agricultural Research Service conducts laboratory and field research.
Question 7 · Agribusiness and Economics
Answer: B. $3,600
Simple interest = principal × rate × time in years: $60,000 × 0.08 × (9 ÷ 12) = $3,600. The $4,800 figure charges a full year of interest, and $4,320 treats 9 months as 0.9 of a year. The $400 figure is the interest for a single month.
Question 8 · Plant and Soil Science
Answer: A. Drying the corn to roughly 14% moisture before binning
Wet grain and the molds on it respire, releasing heat and moisture that migrate upward and form a warm, crusted layer; drying corn to a safe storage moisture of about 13–15% stops that activity. Bin sanitation and cleaning out fines are good practices, but neither removes the excess water that drives the spoilage. Sealing the vents would trap moisture and make the heating worse.
Question 9 · Agricultural Mechanics, Engineering, and Technology
Answer: C. 3 hp
Work = 1,100 lb × 15 ft = 16,500 ft-lb, and power = 16,500 ÷ 10 s = 1,650 ft-lb per second; 1,650 ÷ 550 = 3 hp. Dividing the work by 550 without dividing by the time gives 30, dividing it by the per-minute constant of 33,000 gives 0.5, and dividing 1,650 by 746 confuses foot-pounds per second with watts.
Question 10 · Natural Resources and Environmental Science
Answer: C. Wind: output is intermittent and needs backup generation
Wind turbines generate only when the wind blows, so other generation or storage must cover calm periods. Nuclear plants release almost no carbon dioxide during operation; their drawbacks are high construction cost and radioactive waste. Natural gas emits roughly half the carbon dioxide of coal per unit of energy, and geothermal plants use heat from the earth rather than a mined fuel.
