Like if I think it's a straight line, could I assume it is a straight line even though the question doesn't tell me?

For example, three points on this line - A, B, and C. AB is a straight line and BC is a straight line, could I assume AC definitely is simply because the lines looks like a straight line per the diagram?

I think the question is in general, should I make assumptions based on how the diagram reflects on my eye balls? If so, could I make assumptions for all (whether it's a square vs rectangle) or some (a straight line)?

Problem Solving
Figures: All figures accompanying problem solving questions are intended to provide information useful in solving the problems. Figures are drawn as accurately as possible. Exceptions will be clearly noted. Lines shown as straight are straight, and lines that appear jagged are also straight. The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero. All figures lie in a plane unless otherwise indicated.

Data Sufficiency:
Figures:
• Figures conform to the information given in the question, but will not necessarily conform to the additional information given in statements (1) and (2).
• Lines shown as straight are straight, and lines that appear jagged are also straight.
• The positions of points, angles, regions, etc., exist in the order shown, and angle measures are greater than zero.
• All figures lie in a plane unless otherwise indicated.
