Answer: What best describes the sentence is "It is subjective because it reflects feelings and opinions".
Step-by-step explanation: A subjective sentence is a sentence that has been influenced by personal opinions and emotions. In other words, unlike an objective sentence, a subjective sentence presents a writer's/speaker's judgement or perception about a particular topic, person or thing. The sentence taken from a summary about The Hot Zone can be considered a subjective sentence because it includes an individual's opinion about the text "The Hot Zone", which is mainly shown by the choice of certain words such as "brilliantly" and "fascinating".
