If you give two pieces of information, like in the two sentences above, the reader does not know what to make of them - they are just two pieces of information without interpretation or connection. They don't really mean anything yet.
But, when you add a connecting word like "Nevertheless", suddenly the reader knows what you are thinking; you are indicating that it is surprising.
In contrast, if you say "so" you are showing that one thing led to the other - it is not an unexpected connection.
Facts alone are not enough in most academic writing, such as essays and reports.
It is necessary to give facts some "meaning"
"There are two cats" is a fact, and so is "The couch is scratched". To give these facts a point or meaning, you need to put them together somehow.
|"There are two cats and the couch is scratched".||(I don't want to say the cats did it, but...)|
|"There are two cats, so the couch is scratched".||(I think the cats did it)|
|"There are two cats, and consequently the couch is scratched".||(The cats did it and this sort of thing is normal)|
You, the writer, have to choose the words you use carefully so that you communicate what you really mean.
