20/40 vision means that the test subject sees at 20 feet what a normal person sees at 40 feet. Another way of saying this is that a person with 20/40 vision has vision that is only half as good as normal-or, objects must be at half the normal distance for him to see them.

The three most important compromises that pertain to slavery and territory are: the Missouri Compromise, the Compromiâ¦se of 1850, and the Kansas-Nebraska Act. The Missouri Compromise of 1820 admitted Missouri into the union as a slave state and admitted Maine as a free one. It is also stated that any land in the Lousiana Purchase, south of the latitude 36 degrees thirty was open to slavery; and slavery was prohibited in any territory north of the specified latitude.
