Writing Feedback / Reading books continuous/ separate ; Which is better? [2]

In my opinion, I prefer to read book in separated part than to read it continuously.

Because of two following reasons: The first reason is that I'm a slow reader. To understand whole story I have to read it carefully. For example, to figure out why there's a ghost in the phantom of the opera, I spent two hours reading two pages again and again.

The second reason: I'm a busy person. To manage time more effectively, I usually have a daily plan to work, to have fun with friends, to take care of my family. Only little time left for reading book so that I used to read 1 chapter each.
