4. Samples from a ceramic vase found at a tomb in Sicily prove that the vase was manufactured in Greece. Since the occupant of the tomb died during the reign of a Sicilian ruler who lived 2,700 years ago, the location of the vase indicates that there was trade between Sicily and Greece 2,700 years ago.

Which of the following is an assumption on which the argument depends?

(A) Sicilian potters who lived during the reign of the ruler did not produce work of the same level of quality as did Greek potters.

(B) Sicilian clay that was used in the manufacture of pottery during the ruler’s reign bore little resemblance to Greek clay used to manufacture pottery at that time.

(C) At the time that the occupant of the tomb was alive, there were ships capable of transporting large quantities of manufactured goods between Sicily and Greece.

(D) The vase that was found at the Sicilian tomb was not placed there many generations later by descendants of the occupant of the tomb.

(E) The occupant of the tomb was not a member of the royal family to which the Sicilian ruler belonged.

The answer is D.

The conclusion of this passage is that Samples from a ceramic vase found at a tomb in Sicily prove that the vase was manufactured in Greece. The given reason, as per the statement, is that the location of the vase indicates that there was trade between Sicily and Greece 2,700 years ago.

However, if the Sicilian potters could make the products of the same level of quality as did Greek potters, then the reason that there was trade between Sicily and Greece 2,700 years ago will not necessarily lead to the conclusion that the vase was made by Greeks. It was likely that it was Sicilian potter who made the vase and put it there. Therefore, A should alslo be a correct answer.

Please comment. Thx.

(A) Sicilian potters who lived during the reign of the ruler did not produce work of the same level of quality as did Greek potters.

Please see an example as the following:

aMM gave you an apple, so you claimed you had two apples.

Q: Which of the following is an assumption on which the argument depends?

(a) the fruit aMM gave you was not an orange;

(b) you had one apple before aMM gave you the other one.

(b) is correct

Key: (a) states something correct, but it just repeats the premise, and it doesn’t help to explain the logic here why you had two apples after you got one from aMM. At the same time, usually there is nothing to refute with the premise itself, also we don’t regard premise as assumption.

…… Hope it helps.
