Over 40,000 lead seals from the early Byzantine Empire remain today. Apart from the rare cases where the seal authenticated a document of special importance, most seals had served their purpose when the document was opened. Lead was not expensive, but it was not free: most lead seals would have been recast once they had served their purpose. Thus the number of early Byzantine documents sealed in such a fashion must have been many times the number of remaining lead seals.

Which one of the following statements, if true, most strengthens the argument?

(A) Most of the lead seals produced during the early Byzantine Empire were affixed to documents that were then opened during that period.

(B) Most of the lead seals produced during that early Byzantine Empire were affixed to documents that have since been destroyed.

(C) The amount of lead available for seals in the early Byzantine Empire was much greater than the amount of lead that remains in the seals today.

(D) During the time of the early Byzantine Empire there were at most 40,000 documents of enough importance to prevent the removing and recycling of the seal.

(E) During the time of the early Byzantine Empire there were fewer than 40,000 seals affixed to documents at any given time.

Answer D is incorrect because it does not really support the conclusion that "Thus the number of early Byzantine documents sealed in such a fashion must have been many times the number of remaining lead seals. " We can understand the argument in the following way:
number of remaining (reused) seals = X
The seals that were not recycled were probably destroyed together with documents and there is no correlation between their number and the number of the remaining seals. We don't know how many times a seal could be recast but probably many. Thus the total number of sealed documents of no special importance = X times Y
Y - how many times a seal was reused
[Reveal] Spoiler:
D
tells us that 40000 seals could not be recycled. The number of seals that could not be recycled has no influence on the number of the recycled/ remaining ones and thus answer D is irrelevant.

Hey Jlgdr,
Let me first break down the argument.
The argument states that "the number of early Byzantine documents sealed in such a fashion must have been many times the number of remaining lead seals."
The assumption here is that these lead seals were used on documents that ended up being opened and as a consequence recycled. In other words "most of the lead seals produced were opened during that period" and as a consequence recycled.

Option A says this and supports the argument.

Let's play devil's advocate here to ascertain the validity of option A.
If it were found that No, Most of the lead seals produced during the early Byzantine Empire were affixed to documents that were NOT opened during that period. I.e. they remained sealed forever. Then the assumption that 'these lead seals were recycled' will be broken - therefore breaking the conclusion!

By doing this negation we realise that this option is quite relevant.

Hope that clarified things
