Every request goes through the master. It returns the location of the data, a very short message. The chunk servers then take the much greater time to return the data to the client.

It‘s a queueing strategy where you get in a single file checkout line at a store and a master clerk tells you to go to cash register 5. The following customer is told to go to cash register 7 because register 6 is still processing a customers purchase. It takes the master clerk a second or so to find a free register for the next person in line but it takes the cash register clerk a few minutes to process your purchase.

You know that we do not provide answers to homework here. Now that you have the hints from @jedishrfu what are *your* answers to the questions that you listed...

This example wasn't very clear to me as I am from different culture and traditions probably.
