TSI - Texas Success Initiative Reading and Textual Analysis Questions and Answers
Read the following passage and answer the question below. "The monarch butterfly, with its vibrant orange and black wings, is a marvel of nature. Each fall, millions of these delicate insects embark on a monumental journey, migrating up to 3,000 miles from the northern United States and Canada to their overwintering grounds in central Mexico. This multigenerational migration is a unique and complex phenomenon. The generation that flies south is not the same one that returns north the following spring. It takes several generations to complete the round trip. Unfortunately, the monarch population has seen a steep decline in recent years due to habitat loss, climate change, and the reduction of milkweed, the sole food source for monarch caterpillars." What is the main idea of the passage?
