Explanation:

Purpose of an Index in Informative Text

An index in an informative text serves an essential function for readers seeking specific information. The primary purpose of an index is that it shows readers where to find information on a specific idea, term, or person. This allows readers to quickly locate relevant sections of the text without having to sift through all the content.

For example, in a textbook about biology, if a student wants to learn about 'Photosynthesis,' they can refer to the index, find the page numbers where this topic is discussed, and jump directly to those sections. This not only saves time but also enhances the efficiency of information retrieval.

Moreover, while other options like glossaries and tables of contents provide valuable information, they do not serve the singular purpose of the index, which is specifically designed for precise navigation in extensive texts.
