And that's how you write an interesting paper for both you and your audience.
For example, I have to write a research paper and I chose "History of Lego".
"With more than 20 billion Lego bricks produced per year, more than 915 million ways to combine six Lego bricks and with a production of 306 million tyres a year, Lego, the world’s largest manufacturer brings joy to our children since 1932 (Lego Facts). Lego is a simple toy destined to become a complex structure. Kids, and even adults, from all around the world buy these simple plastic bricks in order to build bigger things such as a replica of the Eiffel Tower, or the Chinese Wall, or even Hogwarts from Harry Potter. We all know how successful the Lego brand is right now, but how did it all start?"
I learned lots of things about my favorite toy, and it's got enough facts for the professor to be satisfied.
