As a solver, the very first step is to figure out what the examiner wants out of you. The examiner wants you to choose an answer option that is most strongly supported by the statements. Each answer option is a hypothesis as indicated by the stem of the question. Now that your answer option must be 100 percent supported/validated by the para, you shall read and understand the statements. Let's state the facts:
Fact #1 -> 32 ancient gold coins were minted in Morocco.
Fact #2 -> The 32 coins were discovered in the ruins of an ancient Jordanian city.
Fact #3 -> This Jordanian city is some 4,000 kms to the east of Morocco.
Fact #4 -> When the discovery happened, Jordanian city was an important trading center along the trade route linking China and Europe.
Fact #5 -> The Jordanian city was also a stopover for pilgrims on the route between Morocco and Mecca.
Fact #6 -> The purse of a trader in the Jordanian city would probably have contained a more diverse set of coins.
(This fact, which is in actuality an opinion of the author, suggests that the discovered bag very likely did not belong to any trader from the Jordanian city.)Since we're dealing with a conclusion question, the right answer must simply be validated by the para. The statements given will serve as premises/evidences to the hypothesis, which, by the way, is the right answer. Answer options that are out of context along with those that are very extreme can be eliminated. Now, let's eliminate the incorrect answer options.
