Final Answer:
The imagery used in the first paragraph to describe the horse is PRIMARILY associated with
(E) power.
Step-by-step explanation:
The key to identifying the primary association lies in the language used to describe the horse in the first paragraph. Phrases such as muscular frame rippling sinews and savage power evoke a sense of strength and dominance aligning with the concept of power rather than athleticism endurance machinery or nature.
In the given context athleticism refers to physical prowess and agility which may be suggested by terms like speed or agility rather than the emphasized strength in the description. Endurance usually involves more sustained and prolonged effort which is not the central focus of the imagery provided. Machinery and nature are not prominent themes in the description making them less likely associations compared to the evident emphasis on the horse's raw power.
The calculation involves a careful consideration of the descriptive language and its implications. Counting the instances of words like muscularsinews and power reveals a dominance of terms related to strength and might. Therefore the answer E power accurately encapsulates the primary association conveyed by the imagery in the first paragraph.
