A small, abbreviated mark on a line.

A small, abbreviated mark on a line.

• A. WAC
• B. Longitude
• C. Tick
• D. Map

Answer: (C)

The main idea here is recognizing the term used for a small mark that appears on a line to show a measurement or division. That tiny mark is called a tick (a tick mark). It’s a short, often perpendicular intrusion on the line that marks an increment, such as a distance or scale division, making it easy to read off values at regular intervals. On maps or charts, ticks give quick visual cues for estimating distances or steps along a line. WAC is just a type of chart, not a mark on a line. Longitude is a continuous geographic line on a globe or map, not a small short mark. A map is the whole depiction, not the individual mark. So the small, abbreviated mark on a line is a tick.
