Answer:
Serious
Explanation:
The passage introducing the test above indicates that the tone of the story will be serious. In most passages, the introductory words serve as a means of telling the reader what he can expect from the passage. It is worded as a warning to the reader that the text will contain views that might be unacceptable to the reader.
This shows that the passage will not be humorous, informal, or light-hearted rather, it will contain views that are strongly worded and ideas that might be offensive to the reader.
