Answer:
Answer is option A (sharp detail, count the strings, heard…breathing).
Explanation:
From the paragraph, it is clear that the person is participating in a game. The excitement and the enhanced alertness (because of acute senses) felt by the person when participating in the sport is due to the release of adrenaline hormone into their circulatory system.
If a person's senses are acute or have an acute mind, it means that the person's senses (sight, hearing, or smell) are very sensitive and powerful and so, that person must be very quick to notice things and can understand them clearly.
The clues that the reader would be most likely to use in determining the meaning of the word acute are 'sharp detail, count the strings, heard…breathing,' etc present in the paragraph.
