Question

the diagram represents a side view of the milky way galaxy. the dotted line represents the outer edge of the galaxy
at approximately which position is earths solar system located?
select the correct answer.

Explanation:

The Earth's solar system is located in the Milky Way galaxy, about halfway between the center of the galaxy and the outer edge, in one of the spiral arms (the Orion Arm). From the diagram, the position that is not at the center (the middle circle) and not at the extreme outer edge or the far - left, but in a position between the center and the outer regions (like the second circle from the left or the one on the lower right - but more accurately, in a spiral arm between the core and the edge) corresponds to the solar system's location. Typically, in such a diagrammatic representation of the Milky Way's side view, the solar system is in a position that is in the disk of the galaxy, not at the center (the central bulge - middle circle) and not at the very outer edge (the dotted line's extreme ends) but in one of the arms. So, looking at the diagram, the position that is in the disk, between the center and the outer edge (for example, the second circle from the left or the lower - right circle, but more precisely, in the region of the spiral arm) is where the solar system is. If we consider the standard knowledge, the solar system is in the Orion Arm, about 26,000 light - years from the galactic center, so in the diagram, it would be a position that is not the central circle (galactic center) and not the outermost dots, but in the disk part (like the second circle from the left or the lower - right circle).

Answer:

(Assuming the circles are labeled from left to right as A, B, C, D with A being leftmost, B next, C center, D lower - right) B (or the appropriate labeled position that is in the disk between center and edge, e.g., if the second circle from the left is the correct one, then that position's label). If we follow the diagram's visual, the solar system is in a spiral arm, so the position that is in the disk (not center, not extreme edge) – for example, the second circle from the left or the lower - right circle. If we have to pick from the diagram's elements, the position that is in the disk of the galaxy (not the central bulge, not the far - left or extreme outer edge) is where the solar system is. So, for example, if the circles are: leftmost (A), second left (B), center (C), lower - right (D), then the answer is B (or D depending on the arm, but more likely the second from left or the lower - right as part of the disk).
