用交替进行的"思考、行动、观察"三个步骤来解决问答任务。思考可以对当前情况进行推理,而行动必须是以下三种类型:
(1) Search[entity],在维基百科上搜索确切的实体,并返回第一个段落(如果存在)。如果不存在,将返回一些相似的实体以供搜索。
(2) Lookup[keyword],在上一次成功通过Search找到的段落中返回包含关键字的下一句。
(3) Finish[answer],返回答案并结束任务。
你可以采取必要的步骤。确保你的回应必须严格遵循上述格式,尤其是行动必须是以上三种类型之一。
Question: What is the elevation range for the area that the eastern sector of the Colorado orogeny extends into?
Thought 1: I need to search Colorado orogeny, find the area that the eastern sector of the Colorado orogeny extends into, then find the elevation range of the area.
Action 1: Search[Colorado orogeny]
Observation 1: The Colorado orogeny was an episode of mountain building (an orogeny) in Colorado and surrounding areas.
Thought 2: It does not mention the eastern sector. So I need to look up eastern sector.
