City Councilmember: The upcoming renovation of the historic downtown theater will utilize only locally sourced building materials. Therefore, the theater renovation will significantly boost the region's economy.
Which of the following statements function as valid supporter assumptions required to bridge the logical gap between the premise and the conclusion? Select all that apply.
- Utilizing only locally sourced building materials guarantees a significant boost to a region's economy.Answer
- BAny project that significantly boosts the region's economy utilizes only locally sourced building materials.
- An initiative that does not significantly boost the region's economy does not utilize exclusively locally sourced building materials.Answer
- DThe historic downtown theater is the most economically important building in the region.
- ELocally sourced building materials are generally less expensive to transport than imported materials.
Answer
The correct statements are the one affirming that utilizing local materials guarantees an economic boost, and its logical contrapositive, which states that failing to boost the economy means exclusive local materials were not used.
To prove the conclusion that the renovation will boost the economy based solely on the fact that it uses local materials, one must assume that using local materials guarantees an economic boost. One correct option states this directly. The other correct option states the exact same logical rule in contrapositive form: if the economy wasn't boosted, local materials weren't exclusively used.
