Detail about MCQs
The phrase “rule of thumb” typically refers to a practical, approximate guideline or principle rather than a precise or strict rule. It’s often used to describe a method or approach that is based on experience or general knowledge rather than exact measurement or calculation. The origin of the phrase is not entirely clear, but it’s commonly believed to have originated from the use of the thumb as a rough measuring tool in various contexts, such as estimating the length of an object or the temperature of food. Over time, it has evolved to represent any broadly applicable and easy-to-remember rule or guideline. So, in the context of your question, the correct interpretation is D. A rough estimate.
