Question

When considering what happens during the Fall Equinox in the Northern Hemisphere, the first idea to evaluate is the balance of day and night lengths across latitudes. 
Option 1 states: 'have 12 hours of darkness and 12 hours of daylight.' This reflects the equinox condition, when the sun is directly above the equator and the length of day and night is approximately equal. In most places this balance is close to 12 hours each, making this statement accurate for the equinox.
Option 2 claims: 'have more hours of darkness than of daylight.' This would describe an equinox scenario near the autumnal limit in some high-latitude regions might appear slightly longer nights, but the defining feature of the equinox is equality, not a net excess of darkness, so this option is inconsistent with the term equinox.
Option 3 asserts: 'have more hours of daylight than darkness.' That would imply a solstice effect where days are longest, which occurs near the summer solstice, not the equinox. On the equinox, daylight and darkness are intended to be equal, so this option misreads the event.
Option 4 says: 'have daylight length greatest at the Equator.' While day length variation with latitude exists, the equinox does not confer a greatest daylight length at the equator; instead, day and night are equal nearly everywhere, with small deviations due to atmospheric refraction. This makes the claim inaccurate in the context of the equinox.
Taken together, the core concept is the alignment of day and night lengths at the equinox, which supports Option 1 as the correct description, while the other options misstate the balance or misinterpret how daylight varies with latitude during that event.
