(1) Imagine that you are writing the discussion section 
of a paper about your current or past research. 
Consider your most important results, and consider the 
broader context of the field in which you are working. 
In a couple of paragraphs, describe the work of at 
least two other groups in your field, and how their 
results relate to what you are doing. Note: in case you 
don't have final results yet, then simply describe the 
key results from at least two groups working in your 
field, whose work you will want to compare with your 
own when you write the discussion section of your 
actual paper.

(2) While your current research is certainly excellent, 
there must be some simplifying assumptions that you 
make, or some factors that limit the certainty of your 
conclusions. In one paragraph, describe these 
limitations and simplifying assumptions, and discuss 
how future studies can improve upon them.
