问题 Anxiety is believed to ______ diabetes by raising levels of the stress hormone cortisol which regulates insulin and blood-sugar levels.
选项 A、impede
B、exacerbate
C、inherit
D、facilitate
答案B
解析 B项“exacerbate恶化”符合题意，如：a speech that exacerbated racial tensions(一个加剧了种族间紧张的演讲)。其他三项“A项impede阻止；C项inherit继承；D项facilitate帮助，推动”都不正确。本题空格处是说焦虑被认为会使糖尿病恶化。因此B项为正确答案。
