Which eraser is best suited for large areas due to its block shape?

The best choice for erasing large areas due to its block shape is the gum eraser. Gum erasers are versatile and typically larger than other types of erasers, which makes them particularly effective for covering more extensive areas when removing pencil marks. Their flexible texture allows them to adapt to the surface of the paper, making them efficient and reducing the risk of tearing or damaging the paper.

In contrast, kneaded rubber erasers are more suited for targeted erasing and adjusting highlights, as they can be shaped by hand to a point or edge but are less effective for large areas. The pink eraser, while functional, is not designed in a block shape and generally has a harder texture than gum erasers, which can make it less effective for large surface areas. Vine charcoal, while not an eraser, is a medium used for drawing rather than for erasing and does not serve the purpose of erasing at all. Therefore, gum erasers are the most effective option in this context.
