Why is is relevant? Leebo at 2019-05-05 17:40:40 UTC What is particularly confusing about it? Did you try looking it up in a Japanese dictionary? Not an English-Japanese dictionary, but one that is just written in Japanese. You can find examples of the usage there, such as さかんに活動する火山 A vigorously active volcano 夜間活動する動物 An animal that is active at night I'm not sure what you found confusing though, or why you might doubt its relevance, so I'm not sure if that helps you at all.
