The sentence “Abstain from all appearance of evil” is an imperative statement. These types of sentences usually do not have a subject and their structures consist mainly on the bare verb alone. The main purpose of an imperative statement is to give commands. So, in this sentence, there is no subject and it is commanding somebody to abstain from doing something.
The excerpt uses explicit details in the following way: it provides a <u>physical description</u> of Sarah Penn (small woman, short waist, gray hair, mild forehead, downward lines about her nose and mouth). All of it is explicit, since there is no room for interpretation, it is what it is. In other words, such details are concrete ones, since they are physical and nothing else.
As for implicit details, we can find them in a figure of speech (a <u>hypallage</u>, which uses an adjective or participle to describe a noun other than the person or thing it is in fact describing): we learn Sarah Penn's forehead was benevolent, that is, it showed her benevolence (an implicit detail, since it was Sarah, and not her forehead, that was benevolent). It is a trait which implicitly tells something about the character's personality. There is also the description of <u>meek downward lines</u> about her nose and mouth. Again, a hypallage which implicitly tells us something about the character: it is Sarah who is gentle and humble, and not the lines about her nose and mouth.
Ok the setting is clearly outside.
The first point could be that the description of the growling dog gives an effect of being surrounded by danger, especially with the repetition of the growling coming from everywhere.
It give a feeling of being trapped and Stephen king uses this to create tension.
The second point could refer to the woman and her strange actions because she is frightened of the unknown, and often being in the outside exposes you to things you can’t always escape from. King uses this to convey a fearful setting that a reader can relate to.
I hope this helps :)
He is upset and no longer wants to attend the school.
