Final answer:
The number of correct answers required to earn a benchmark varies depending on the context or specific standards. Benchmarks are based on percentages or grading rubrics, and meeting them indicates a certain level of proficiency.
Step-by-step explanation:
How many correct answers does it take to earn a benchmark? The correct option is B) It varies. This can depend on the context or the requirements set by an instructor or testing standards.
In some cases, benchmarks are set based on a percentage of correct answers or according to a grading rubric. For example, if the 70th percentile for a 20-question math test was 16 correct answers, then students who answered at least 16 questions correctly performed better than 70% of the test-takers.
To earn a benchmark, one must meet or exceed the defined standard, which can be different in each scenario.
