What range describes the high failure rate?

• A. 64% to 85% of examinees do not pass.
• B. 10% to 20%
• C. 30% to 40%
• D. 50% to 60%

Answer: (A)

A high failure rate means most examinees do not pass. That’s the idea: the proportion failing is well over half. The option that describes a large majority of examinees not passing fits this, so it best conveys what “high failure rate” means. The other ranges describe only smaller fractions failing, which wouldn’t be considered a high failure rate. In short, when the majority fail, that reflects a high failure rate.
