The opportunity cost for the Congo to produce additional diamonds is <u>C. 4 thousand units of corn</u>.
<h3>What are opportunity costs?</h3>
Opportunity costs are the benefits of an alternative decision when the decision maker rejects the alternative.
For instance, the opportunity cost of going to college is the earnings forgone.
The opportunity cost is computed as the lost benefit when an alternative decision is not pursued.
Fractionally, the opportunity cost of producing one product A) to another (B) = Units of B / Units of A.
<h3>Data and Calculations:</h3>
United States opportunity cost to produce diamonds = 60/10 = 6
United States opportunity cost to produce corns = 10/60 = 1/6
Congo's opportunity cost to produce diamonds = 20/5 = 4
Congo's opportunity cost to produce corn = 5/20 = 1/4
Thus, the opportunity cost for the Congo to produce additional diamonds is <u>C. 4 thousand units of corn</u>.

The correct answers are validity; reliability.
Answer 1: <span>The ability of a test to measure what is purports to measure is called validity.</span> Validity is defined as the ability of a test or study to actually to measure what it claims to measure. For instance, if a test aims to measure a population sample's heart rate, but ends up measuring blood sugar levels instead, it does not have validity, since it did not measure what it claimed or set out to measure. <span>
