Use the article to answer the question. Which sentence from later in the text best helps develop the idea expressed in paragraph 2? (1 point) Responses By targeting more than 3,000 genes of interest, the researchers could tease out the variations between humans and tortoises. By targeting more than 3,000 genes of interest, the researchers could tease out the variations between humans and tortoises. Thanks to this analysis, the researchers were able to narrow down their original list of 3,000 genes to 43 specific sequences that might have contributed to Lonesome George’s long, disease-free life. Thanks to this analysis, the researchers were able to narrow down their original list of 3,000 genes to 43 specific sequences that might have contributed to Lonesome George’s long, disease-free life. Their long, slow existence “has been key to their survival — from a time of overexploitation to a time of greater enlightenment and conservation,” she wrote in an email. Their long, slow existence “has been key to their survival — from a time of overexploitation to a time of greater enlightenment and conservation,” she wrote in an email. Lonesome George was a conservation icon, Caccone said, but a conservation icon that can also provide insights into human health and aging. Lonesome George was a conservation icon, Caccone said, but a conservation icon that can also provide insights into human health and aging.

Answer 1

The sentence that best helps develop the idea expressed in paragraph 2 is: "Thanks to this analysis, the researchers were able to narrow down their original list of 3,000 genes to 43 specific sequences that might have contributed to Lonesome George’s long, disease-free life." This sentence supports the idea by detailing the outcomes of the research and emphasizing the significance of the targeted genes in understanding the longevity of Lonesome George.
