Given a scientific passage and an answer, generate a question for the given answer.

[EX Q]: Passage: Oxygen is needed to make ozone. Ozone is a molecule made of three oxygen ions. Ozone in the upper atmosphere blocks harmful solar radiation from reaching the surface. Without oxygen, life on Earth would have been very simple. Answer: three
[EX A]: How many oxygen ions make up an ozone molecule?

[EX Q]: Passage: The most noticeable magnetic activity of the Sun is the appearance of sunspots. Sunspots are cooler, darker areas on the Sun's surface ( Figure below ). Sunspots occur in an 11-year cycle. The number of sunspots begins at a minimum. The number gradually increases to the maximum. Then the number returns to a minimum again. Answer: 11

[EX Q]: Passage: Relief , or terrain, includes all the landforms of a region. A topographic map shows the height, or elevation , of features in an area. This includes mountains, craters, valleys, and rivers. For example, Figure below shows the San Francisco Peaks in northern Arizona. Features on the map include mountains, hills and lava flows. You can recognize these features from the differences in elevation. We will talk about some different landforms in the next section. Answer: topographic
[EX A]:
What type of map shows the elevation and features in an area?
