Explanation:

To determine why Lyme disease is less common today, we analyze the options. Knowing when it began (first option) doesn't directly reduce cases. People spending less time outdoors (second option) is not indicated in the text. The text shows doctors investigated and made a medical discovery, implying understanding the cause (third option, "because now we know what causes it") allows for prevention measures, reducing disease occurrence.

Answer:

because now we know what causes it
