Question 36
The demand for agricultural produce is generally
Options
A) elastic
B) inelastic
C) unitary
D) static
The correct answer is B.
Explanation:

Question 40
The wear and tear of farm structures over time is described as
Options
A) appreciation
B) depreciation
C) capitalization
D) salvage value
The correct answer is B.
Explanation:
Machinery and equipment are major cost items in farm businesses. Larger ma¬chines, new technology, higher prices for parts and new machinery, and higher energy prices have all caused machinery and power costs to rise in recent years. Depreciation is a cost resulting from wear, obsoles¬cence, and age of a machine. The degree of me-chanical wear may cause the value of a particular machine to be somewhat above or below the aver¬age value for similar machines when it is traded or sold. The introduction of new technology or a major design change may make an older machine suddenly obsolete, causing a sharp decline in its remaining value. But age and accumulated hours of use are usually the most important factors in determining the remaining value of a machine. Choice B is correct. The wear and tear of farm structures overtime is described as depreciation

The correct answer is B.
Explanation:
Legumes—primarily clover and alfalfa (lucerne)—have leaves with less structural material and are generally higher in protein, energy, and calcium than grasses. Legumes become less leafy and more stemmy as they mature. Conversely, grass leaves become more lignified as they mature, and are therefore less digestible.
Legumes form symbiotic relationship with bacteria, rhizobium in the nodules of their roots to manufacture nitrogen compounds, which in turn serve as protein in the legumes, and seed being part of their storage form.
