The author of the book The Chipko Movement: A People’s History is:

CONCEPT

For a book-authorship question, the governing evidence is the title page or an authoritative bibliographic catalogue. Similar personal names cannot substitute for a documented author-title relationship.

Set-based choices such as “more than one” and “none” must be tested only after checking every named person against that bibliographic record.

APPLICATION

Bibliographic records for The Chipko Movement: A People’s History identify the historian and environmental activist Shekhar Pathak as its author. Therefore, the offered name Shekhar Pathak matches the documented author-title relationship.

CONTRAST

• Shekhar Joshi was a noted Hindi short-story writer; his literary identity does not match the credited authorship of this title.

• Shekhar Pandey is not the author credited in bibliographic records for this title.

• “More than one of the above” would require at least two listed people to be credited authors, whereas the record identifies one.

• “None of the above” would require every listed name to fail, whereas one listed name matches the record.

RESULT

The author is Shekhar Pathak.
