A.I. Explanation:

Option 1: "Human beings are the only organism that makes extensive use of technology to extend the limits of its natural tolerance range. but some stars are too cold and some are too hot. Only about 20% can be considered as suitable."

Explanation: This option incorrectly combines two separate ideas from the text without capturing the main theme. While it mentions human beings and their use of technology, it fails to summarize the overall focus on animal migration and survival in changing environments. The mention of stars is irrelevant to the main point.

Option 2: "Animals migrate to find a new habitat because the change of environment and only species that have the tolerance for new environment could survive and reproduce."

Explanation: This option accurately summarizes the main idea of the text, which discusses how animals migrate in response to environmental changes and the necessity of tolerance for survival and reproduction. It captures the essence of the text's focus on adaptation and survival.

Option 3: "For the development of civilizations, only a small amount of planet is livable. Because there are some factors for species and animals to survive and reproduce. Therefore, animals migrate to find new habitat and only species that can tolerant for new environment could survive and reproduce. However, human beings use technology to extend the limits of their natural tolerance range."

Explanation: This option, while touching on several points from the text, is overly complex and introduces unnecessary details that dilute the main idea. It attempts to summarize too many aspects, including civilization development and human technology, which are not the primary focus of the text.

Option 4: "Some stars are too cold and some are too hot. Only about 20% can be considered as suitable. We all know that there are some factors for species and animals to survive and reproduce, including environmental conditions, temperature, and tolerance range."

Explanation: This option focuses primarily on the suitability of stars for civilization development, which is not the main theme of the text. While it mentions factors for survival, it does not address the critical point about animal migration and adaptation, making it an incomplete summary.
