Critical Reasoning: Inference Questions

Which of the following best completes the passage below?

An ancient scripture, about 3500 years old, was deciphered by experts revealing it to be the account of a barter between two tribes. Verified by concurring evidence, the account describes how the Ngebono tribe promised military assistance in exchange for 200 musical instruments, believed to be vital accessories for tribal ceremonies, which were supplied by the Vergiba tribe. However, it has been proven that the latter tribe did not have the technological knowledge to manufacture any items other than ceramic vessels until 2000 years ago so __________.

Incorrect.

[[snippet]]

This answer choice is more like an additional premise than a conclusion. It does not rest on the premises given, but presents new information on the topic.

Incorrect.

[[snippet]]

This answer choice goes too far beyond the premises. The argument contains no evidence to support this remark about the breakout of a war. Such a statement requires too many assumptions to link it to the information we've been given.

Incorrect.

[[snippet]]

This answer choice contradicts the second premise. The argument explicitly says that the account was Verified by concurring evidence, i.e., it was recorded in other evidence. There is no doubt about whether the barter took place.

Excellent work!

[[snippet]]

This answer choice provides a logical conclusion. If ceramic vessels were the only thing the Vergiba could make, it makes sense that the musical instruments they provided were based on ceramic vessels. Thus, this answer choice manages to explain the apparent conflict.

no remnants of the original instruments have been found because of the primitive clay mixture and firing process that was used for their production
the instruments were probably not functional, resulting in a lengthy and violent war between the two tribes
the account was probably fictitious and was created to cease later hostilities by showing how cooperation could benefit both tribes
it is extremely likely that the barter did not actually take place, and that the idea was eventually discarded
the musical instruments were probably based on such vessels, with whatever adaptations required to allow them to be used as musical instruments
