Answer

Brief Explanations:

The passage first introduces tree rings, then explains that narrow rings (dark) mean hard times (cold, disease, etc.) and wide rings (light) mean good times (plenty of water and food). So the main idea is about what wide and narrow rings show regarding the tree each year.

Answer:

Wide rings and narrow rings show differences in what was happening to the tree each year.
