Question 170General Subjects - QMED

The correct answer is B) 2.368 inches. The reasoning behind this is that a vernier caliper, which is a precision measuring instrument, allows for measurements to be taken with a high degree of accuracy. The illustration shows the vernier scale, and by aligning the markings on the vernier scale with the main scale, the reading can be determined to be 2.368 inches. The other options are incorrect because they do not accurately reflect the reading shown in the illustration. Option A (2.308 inches) and Option C (2.380 inches) are off by the precision of the vernier scale, while Option D (2.965 inches) is significantly different from the correct reading.
