Final answer:
The question seems to describe positions of dots relative to hash marks, which could be part of a mathematical problem. However, without additional context or accompanying images, it is not possible to provide a definitive answer.
Step-by-step explanation:
The question provided describes the positioning of dots in relation to other dots and perpendicular hash marks on what could be interpreted as a coordinate grid or diagram, which might be used in a mathematical problem related to geometry or analytical reasoning. Without additional context, it is challenging to provide a precise answer. However, it appears that the question is asking for the filling in of blank statements relating to the number of tracks and what a sign indicates on those tracks. If this were a math question, one might read the description and interpret the positions of dots as points on a grid, potentially relating to a graphing exercise or geometric principles. Nevertheless, due to the lack of complete context in the information provided, it is impossible to answer the question definitively.
