In this task, there seems to be quite an obvious split in the options - what is the reason for kidney damage, is it the supplements themselves (A-С) or the habit of overconsuming them (D-E)?
In my opinion, a much better call is to choose the practice, not the supplements themselves. The reason for it is that it
leads to kidney damage - not 'causes', not 'induces', etc.
Usually, a phenomenon
leads to another phenomenon, a process to process. Sth like: 'planting trees leads to increase in the oxygen levels'. But we don't normally say 'trees lead to high oxygen', right?
It's the fact of their planting that does - which
eliminates A, B and C.So, I'm left with options D and E, where the 'practice' leads to damage. Now, the split is the following:
(D) vitamin supplements, a practice that can, potentially, lead to
(E) vitamin supplements, a practice that has the potential for leading to
Again, I feel there's a slight difference in meaning here. While the adverb
'potentially' is somewhat synonymous to possibly, perhaps, maybe etc.,
'to have the potential for sth' is more commonly used
when speaking about someone's abilities, having a promising future, or just room for some future success.
That is, if we say that consumption of extra supplements has the potential for something, we refer to their future results and achievements (normally, clearly, positive) - and to me it looks that the sentence is
more inclined towards the 'possibly' meaning.
Plus, the structure of E is a bit too heavy as well.
Therefore,
I'm settling for D.
