The answer is explained below.
Step-by-step explanation:
The Contest was first published in 1911 in the New York Tribune. It is short story written by English author sir Arthur Conan Doyle, best known by his Sherlock Holmes.
The author's tone refers to the way the author expresses his attitude by their writing; in this case it refers to a mocking tone which can be seen through the next three sentences:
1) The low note was a grunting, a rumble, the deep discordant growling of an ill-conditioned dog.
2) Then suddenly the singer threw up his face, straightened his tubby figure, rose upon his tiptoes, and with wagging head and scarlet cheeks emitted such a howl as the same dog might have given had his growl been checked by a kick from his master.
3) Many a singer far better than this absurd fop had been driven amid execration and abuse from the platform.
