Despite there being no fundamental difference in shipbuilding traditions in Viking-Age Scandinavia from the ones in other parts of Northern Europe, archaeological evidence shows that Viking ships were lighter, slimmer, faster, and thus probably more seaworthy than the heavier vessels used by the English at that time.
A. Despite there being no fundamental difference in shipbuilding traditions in Viking-Age Scandinavia from the ones
B. Despite no fundamental difference between the shipbuilding traditions in Viking-Age Scandinavia from those
C. With shipbuilding traditions in Viking-Age Scandinavia not fundamentally different from those
D. With the shipbuilding traditions in Viking-Age Scandinavia having no fundamental difference from the ones
E. Although shipbuilding traditions in Viking-Age Scandinavia were not fundamentally different from those
The split between 'Despite', 'With' & Although and 'the ones' & 'Those'.
'The ones' is awkward so eliminate D & A
Left with B, C & E
Now this is contrasting sentence so with can not be use to contrast so eliminate C
now Despite used as 'first positive outcome than contrasting negative one'
and Although used as 'first negative outcome than contrasting positive one'
now the negative outcome is that the technique are same for both the viking and other region but positive is that the voking ships are better and lighter so Although is qualifying the task and hence
E is the best answer
