Hello. You have not informed which book reviews this question is referring to. This makes it impossible for me to answer you specifically. However, I will try to help you as much as I can, giving instructions on how to answer this.
You should read both reviews and observe the position of the review author in relation to the book. It is likely that each author makes different positions on the construction of the narratives, the characters, the writing style, the events, the themes and other elements of the work. These positions can be positive, when they praise the work, or, negative, when they criticize the work. You must identify which author is being positive and which is being negative.
Answer:
it's best to focus on yourself rather than others because sometimes they could take advantage
John once was a jester
he was always seen as a heckler
but he then met a girl in a dream
she was covered in orange cream
he found this to be extremely interesting
as she found her attire to be frustrating
he made an offer she couldn't resist
as he said he would solve her problem with a flick of the wrist
they both watched closely as he did his trick
he made her feel quite the fool as the watch on hist wrist began to tick
she was filled with wonder at what mysterious act he would do and that feeling soon began to fester
he began to laugh at this cruel trick as he said "I'll always be a jester".
It's describing "cookies" which is a noun which makes it an adjective phrase, because adjectives describe nouns :)
