Answer:
poor test-retest reliability
Explanation:
Test-retest reliability: In research, the term "test-retest reliability" is also referred to as "retest reliability" and tends to measure test consistency. In "test-retest reliability", the reliability of a specific test is being measured over a while.
In other words, a researcher tends to give a similar test twice to the same subjects or participants at different times to analyze if the test results are the same.
Example: A specific test is given on Wednesday, then again on the following Wednesday.
In the question above, the given statement represents "poor test-retest reliability".
The correct answer is unobtainable production.
Explanation
On a production possibility curve (which determines the costs of production and possibilities of manufacturing more goods that would provide the best result), data points that fall outside the curve represent a currently unattainable production.
Moreover, this happens due to different situations. For example, lack of labor, materials or even money.
