Cevap
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.
