The lowest aurora can come is 80km above sea level

And the highest balloon can go is 50km above sea level

So the closest will be the lowest level of aurora and highest level of balloon
You can check the diagram for the same.

Hence 80-50 =30km

Hi KarishmaB

Could you please explain part-2 of this question? I don't understand why its answer is 30km.

The diagram to the left is an image of the layers of the earth's atmosphere. It shows the approximate height from sea level of the borders between layers, and it includes several vehicles and atmospheric occurrences within those layers as points of reference.

Use the drop-down menus to complete each statement as accurately as possible on the basis of the information provided.

1. The stratosphere makes up most nearly percent of the height of the atmosphere.

2. If the reference objects in the diagram can exist only in the layer in which they are drawn but can appear anywhere within that layer, the closest that a weather balloon and an aurora could come to one another is kilometers.

Thanks APram

I think I was confused because I had assumed 80km above Stratosphere with the altitude range of 68-148km but it ends at 80km from sea surface with the range of 0-80km. Please correct me if I am wrong.
