Answer :
Final answer:
The New Hampshire vision test requires individuals to read from the Snellen chart to determine visual acuity. A typical requirement is having the ability to read letters with a visual acuity of 20/40, which is the correct answer for the test requirement.
Explanation:
The New Hampshire vision test utilizes the Snellen chart to measure visual acuity. To pass this test, individuals are typically required to read letters from a specific line on the Snellen chart, which corresponds to a certain level of visual sharpness. The measure of visual acuity is represented as a fraction, where the top number denotes the distance at which the test is taken (usually 20 feet), and the bottom number signifies the distance at which a person with normal acuity could read the same line of the chart. According to the Snellen chart system, 20/40 vision means that the smallest letters you can read at 20 feet could be read by a person with normal vision at 40 feet away. Hence, for the New Hampshire vision test, the correct answer is that you must read letters to obtain a reading of 20/40 (option c).
