Economic growth can be encouraged by: an increase in cultural elements
a thriving trade
the production of goods
artistic production

Third option

Explanation:

The production of goods is what will majorly help a economy grow. The creation of products to sell and buy from others is what will keep the economy going in whole. It wouldn't be the second option because although a thriving trade is good without the production of goods you cannot keep trading, it wouldn't be a increase of cultural elements because if anything that is a bad thing. With culture getting in the way of buying and selling that would mean certain things cannot be bought if it affects someones culture. Then it wouldn't be the fourth option because artistic product has little to nothing to do with the economy because it's sold at a high price.

Hope this helps.
