Question

Answer on Passage:

Children are in pursuit of a dog whose leash has broken. James is directly behind the dog. Ruby is behind James. Rachel is behind Ruby. Max is ahead of the dog walking down the street in the opposite direction. As the children and dog pass, Max turns around and joins the pursuit. He runs in behind Ruby. James runs faster and is alongside the dog on the left. Ruby runs faster and is alongside the dog on the right. Which child is directly behind the dog?

Options

A
James
B
Ruby
C
Rachel
D
Max

Explanation

Max is directly behind the dog. Here is the order of the children behind the dog:

Max
Ruby
James
Rachel

Max was originally walking in the opposite direction, but he turned around and joined the pursuit. He ran in behind Ruby, which means that he is now the one directly behind the dog. James and Ruby then ran faster and passed Max, but they are both now alongside the dog, not directly behind it.

Therefore, the only child who is directly behind the dog is Max.

James: James was originally directly behind the dog, but he was then passed by Max. He is now alongside the dog on the left.

Ruby: Ruby was originally behind James, but she was then passed by Max. She is now alongside the dog on the right.

Rachel: Rachel was originally behind Ruby, but she is still behind Ruby and Max. She is not directly behind the dog.

Max is directly behind the dog.

Here is the order of the children behind the dog:

Max
Ruby
James
Rachel

Max was originally walking in the opposite direction, but he turned around and joined the pursuit. He ran in behind Ruby, which means that he is now the one directly behind the dog. James and Ruby then ran faster and passed Max, but they are both now alongside the dog, not directly behind it.

Therefore, the only child who is directly behind the dog is Max.
