q4 Ginko biloba tree. Summarize the points in the lecture and explain how they are related to the reading passage.

The herbal medicine Ginkgo biloba comes from the ginkgo tree. This tree is the oldest surviving tree species in the world and dates back at least 200 million years. The tree is very hardy, resistant to insects, bacteria, viruses, and pollution. For this reason, it is now planted extensively in American cities and used as shade trees. The tree is so hardy that a solitary ginkgo was the only tree to survive the atomic blast at Hiroshima. Ginkgo trees can live for approximately 1,000 years and grow to 100-120 feet high.
