Answer:
Yes your claim is arguable.
Explanation:
Here are some reasons as to why you would prefer reading on a tablet or computer rather than reading from a book.
I much prefer reading on a tablet or computer than reading a book because seeing the book on a screen helps me to focus better. The bright lights help me to pay attention, and a tablet or computer is something I am more familiar with. My brain associates computers and tablets with happiness, because I am usually doing something fun while on the device. This will help me to find reading more fun.
Here is the answer to your initial question.
My claim is arguable because I have examples and reasoning to support it. For example, my brain associates tablets and computer with fun and happiness. Usually, when I am on on of those devices, I am doing something fun that I enjoy. My brain will then associate reading with fun things because I am on a device my brain recognizes as fun.

You could write about a pretty place you have been too! something like this maybe?
I would say one of the most prettiest places I have seen is a beach in Virginia. To get there, you had to walk a couple of miles through a beautiful forest. The forest was so green and the heat of the sun was very hot but the trees covered us with cool shade. Once we got there, we relaxed and cooled off in the water. I felt happy and calm, I would love to do it again some time!
