you have observed some malpractices in your school that you think should be discouraged.write a letter to the headmaster/headmistress discussing at least three of these negative practices and suggest ways they can be checked​

This is the correct way to separate the dialogue in this excerpt:

"Where is Rose?"

"Busy, as usual, with her mice and beetles, I suppose, father," answered Ethel; "we have not seen her all this afternoon."

"She will probably be with you at teatime," said Dr. Sinclair, "after which I should like you to ask her to come to me for a little while in the surgery."

"Very well, father, I won't forget."

Explanation: When dialogue involves two or more people, there needs to be an indent and paragraph for each speaker so the reader knows when one begins and ends their speech.
