I'm sorry, but I don't have access to specific English textbooks for 4th class called "Marigold." Textbook content varies by region, curriculum, and publisher. To find information about the Marigold English textbook for 4th class, I recommend the following:

1. Check your school or local education board's website: They often have lists of approved or recommended textbooks.
2. Contact your child's school or teacher: They will be able to provide the most accurate information about the specific textbooks used in the classroom.
3. Search online bookstores or educational resources: Websites like Amazon or educational publishers' websites might list the textbook if it's widely available.
