Assignment #2 - Update.

The minimum word count for assignment #2 is lowered to 1500 words. However, please take this serious and note the following: 

• This is not meant to be like the introduction of a real scientific article but should start at a bit lower level and can contain ¡°textbook level¡± content.
• This is an important foundation and starting point for your final assignment. Trying to express the topic in your own words is a powerful learning tool.  
• Please do not use lengthy expressions and/or filler word just to meet the word limit.
