Final answer:
The sentence should be corrected to include proper capitalization and punctuation around the quotation by Bernard M. Baruch, ensuring the first word of the quote is capitalized and the final punctuation is placed correctly.
Step-by-step explanation:
The correct version of the sentence with proper capitalization and punctuation would be: "Economist Bernard M. Baruch noted, 'The art of living lies less in eliminating our troubles than in growing with them.'" The quotation is integrated into the sentence with quotation marks, and the first word of the quotation is capitalized, while the rest of the sentence follows standard English capitalization and punctuation rules. When punctuating quotations, it's important to place the final punctuation inside the quotation marks if it's part of the quoted material. The name 'Bernard M. Baruch' also needs to be capitalized as it's a proper noun.
