Answer:
B. An instruction booklet
Explanation:
What is a neutral tone?
A neutral tone is context that lacks positive or negative language. Rather than aiming for a sense of feeling, neutral tone aims for simply explaining facts.
An example of a sentence that has a neutral tone could be "The dog is brown." This would have a neutral tone because if reading it the sentence will have you feeling no certain way as it's speaking facts rather than an opinion which tends to spark feeling.
Looking at the answer choices
An advertisement - As you can imagine, when reading an advertisement you can expect to feel something as the author is trying to get you to buy something. Take burger king for example. At the end of their ads they typically say "Have it your way!." This type of sentence likely has a positive tone as they want you to go to their restaurant. So we can conclude that advertisements would likely have some sort of tone because they want you to feel some way so you will buy their product or service.
An instruction booklet - Imagine you buy a chair and you have to build it using a set of instructions. Imagine the sentence, "Step 2, put the nail through the hole and tighten it," This type of sentence does not create any feeling as it just tells you a fact on how you are going to build the chair. Because no feelings are created while reading instructions, we can say that an instruction booklet would have a neutral tone.
A personal letter - A personal letter will likely have a tone that's not neutral as they are usually written informally which typically creates a sense of feeling. So automatically we can get rid of that answer.
A murder mystery - Like the personal letter, we can infer that a murder mystery will likely want you to feel confused or puzzled to make the mystery interesting, meaning that a murder mystery would likely have a tone other than neutral.
