Every morning I get up at 7 o' clock, I have my breakfast. While I eat, my mother prepares my lunch. When I finish having breakfast, I always take my bike, and I always arrive late! - Hey! What you? - I do my homework.
Answer:
C. It creates an atmosphere of mystery
Explanation:
The passage gives out a few clues:
1. two am
2. stealthy step
3. long black shadow
4. man with a candle
5. notice the 2 key words in the middle of the passage, stealthy and cautiously
