The image displays a page from a textbook or educational material. On the left side, the number "37" is visible, followed by the word "Furan" rotated 90 degrees counter-clockwise. Below this, a skeletal structure of a five-membered ring containing oxygen is depicted. To the right of the Furan section, the word "Pyran" is also rotated 90 degrees counter-clockwise. Below "Pyran" is a skeletal structure of a six-membered ring containing oxygen. The majority of the page contains text, also rotated, discussing ring formation in sugars. Specifically, it mentions five and six carbon sugars undergoing cyclisation to form either a furan or a pyran ring. The text further elaborates on the reaction involving a hydroxyl group. The background of the image appears to be a patterned surface, possibly a table or a book cover. There are no people visible in the image. There is no information in the image that would indicate a location in Jalingo, Nigeria.
