The correct answer is option D. sentence 2, sentence 1, sentence 4, sentence 3. The most logical way to sequence these sentences to create a logical narrative is:
Sentence 2: I decided to ride my skateboard to school this morning.
Sentence 1: As I turned onto Bryce Road, I saw the Parkers’ cat crouched under a tree, hissing at something on the ground.
Sentence 4: Approaching the cat, I noticed that a nest full of tiny birds was on the ground; it must have fallen from a branch.
Sentence 3: I shooed the cat away and called my older stepbrother, a veterinarian, because he would know just how to help them.
In this way, this narrative follows a chronological order in which, first, the narrator decides, in the morning, to ride a skateboard to school. While riding, he/she sees a cat hissing something on the ground. Consequently, he/she approaches the cat to discover a nest full of birds. Finally, the narrator calls his/her stepbrother, who is a vet, because he will be better prepared to help the birds.
