问题 Pauline Gross felt seared because she thought she would die of ______.
From the last paragraph, we know many factors involved in complex diseases, such as gene, lifestyle and ______.
选项
答案environmental influences
解析 定位到文章末段的第二句Genes aren’t the only factors involved in complex diseases—lifestyle and environmental influences, such as diet or smoking, are too．[精析] 同义转述题[考频：22]。由and可知此处要填入名词性成分并与gene，lifestyle形成并列结构。从原文可知，除了基因因素外，生活方式和环境影响也会导致那些复杂疾病的产生，由此可知此处应填入environmental influences。
