Question

you want a book from the library lines on the classroom

Answer 1

this is a conversation between you and you friend for eg. - rohan.

You- hey rohan! look at this book. What do you think whose book this might be?

rohan - see here, there is a stamp of our school's library this means someone has been careless about the book.

you - yes, now what should we do?

rohan - we should ask our class , may be they could provide any help.

you - that's right but English lecture is going to start , so it would be better if we submit the book to the library teacher, he would be able to find about the student from the library records.

rohan - yes you are right, hurry up! or we will be delayed.
