The new research reveals that despite public health efforts to reduce tobacco use, secondhand smoke continues to【C3】______a grievous toll on nonsmokers.

"The【C5】______of information on biomarker-measured(生 物指标测量)exposure allows us to more accurately assess the impact of secondhand smoke exposure on health and productivity. The impact is particularly great for communities of color."
    Exposure to secondhand smoke is linked to a number of【C6】______illnesses including heart and lung disease, as well as conditions affecting newborns such as low birth weight and respiratory distress syndrome. In the research, the scientists【C7】______the economic implications—years of potential life lost and the value of lost productivity—on different racial and ethnic groups.
    "Our study probably underestimates the true economic impact of secondhand smoke on【C8】______," said Max. "The toll is substantial, with communities of color having the greatest【C9】______. Interventions need to be designed to reduce the health and economic burden of smoking on smokers and nonsmokers alike, and on particularly【C10】______groups."

选项
答案N
解析 空格前是副词particularly，空格后是名词groups，故应填人形容词或分词，说明需要特别对待的群体。本句提到我们需要制订干预措施来减轻吸烟者和非吸烟者的健康负担与经济负担，结合上文提到的有色人群(communities of color)伤亡最重，可推断他们是vulnerable groups(易受伤害的群体)。
