Welcome to Wikipedia! If you have any questions about the assignment, please don't hesitate to let me know. Hoopes (talk) 16:52, 23 November 2020 (UTC)
Your addition to the article on Kalibangan consisted only of a list of bibliographic sources that are not tied to any specific content. These were not added to the article in the formats specified by Wikipedia, so they appear as a a separate, unformatted section that will probably be reverted as vandalism. While it is helpful to add additional references, these should be sources that are cited in the text of the Wikipedia article. Please review the article nad see if there are appropriate places to insert correctly formated reference tags. Otherwise, this content is likely to be removed.
