Critical Reasoning: Inference Questions

In a recent press conference, the government promised the citizens of Town Y that the new national highway will not pass through existing archaeological heritage sites neighboring Town Y, including Site Z. However, the new highway will pass within a mile of Site Z, which is situated at the center of an area rich in archaeological sites yet to be completely discovered.

Which of the following inferences is best supported by the statements made above?

Incorrect.

[[snippet]]

This answer choice presents a new premise regarding an additional concern of the citizens. Since there is nothing in the existing premises to support such a statement, this cannot be a valid conclusion.

Incorrect.

[[snippet]]

This answer choice contradicts a premise of the argument which states that the government promised that the highway will not pass through existing archaeological heritage sites. Since the highway will not pass through Site Z but through an area of undiscovered sites, it is incorrect to infer that the government has broken its promise.

Correct!

[[snippet]]

This answer choice provides a likely conclusion to the argument's premises. We are told that the area around Site Z has many undiscovered sites, and that the highway will pass near Site Z, that is, within the area. It is logical to conclude that these undiscovered sites may be damaged in the process.

Incorrect.

[[snippet]]

This answer choice is based only upon premise A,which states that the government has promised not to endanger Site Z. However, premise B contradicts the conclusion in this answer choice as it reveals other sites may be in danger.

Incorrect.

[[snippet]]

The information in this answer choice constitutes quite a leap from the information provided in the premises and requires many assumptions to link it to the argument. Remember - any inference must be based on the given premises only!

The citizens of Town Y are worried that the noise the new highway will generate might discourage tourists from visiting Site Z.
The government has broken its promise to the citizens of Town Y.
Unless the national highway plan is changed, undiscovered archaeological sites will possibly be damaged during the highway's construction.
Now that the government has shown its commitment to preserving archaeological heritage sites, there is no longer a threat to Site Z or to whatever undiscovered archaeological sites there are in its vicinity.
It is not that important if the area around Site Z is damaged by the highway since interest in archaeology is decreasing and the site would not receive many visitors anyway.
