问题     According to a report from the Harvard School of Public Health, many everyday products, including some bug sprays and cleaning fluids, could lead to an increased risk of brain and behavioral disorders in children. The developing brain, the report says, is particularly【C1】______to the toxic effects of certain chemicals these products may contain, and the damage they cause can be【C2】______.
    The official policy, however, is still evolving. Health and environmental【C3】______have long urged U. S. government agencies to【C4】______the use of some of the 11 chemicals the report cites and called for more studies on their long-term effects. In 2001, for example, the Environmental Protection Agency【C5】______the type and amount of lead that could be present in paint and soil in homes and child-care【C6】______, after concerns were raised about lead poisoning. The agency is now【C7】______the toxic effects of some of the chemicals in the latest report.
    But the threshold for regulation is high. Because children’s brain and behavioral disorders, like hyperactivity and lower grades, can also be linked to social and genetic factors, it’s tough to pin them on exposure to specific chemicals with solid【C8】______evidence, which is what the EPA requires. Even the Harvard study did not prove a direct【C9】______but noted strong associations between exposure and risk of behavioral issues.
    Nonetheless, it’s smart to【C10】______caution. While it may be impossible to prevent kids from drinking tap water that may contain trace amounts of chemicals, keeping kids away from lawns recently sprayed with chemicals and freshly dry-cleaned clothes can’t hurt. A)advocates I)particles
B)compact J)permanent
C)correlation K)restricted
D)exercise L)simulating
E)faculties M)statistical
F)interaction N)tighten
G)investigating O)vulnerable
H)overwhelmed [br] 【C8】
选项
答案 M
解析 该空格位于形容词solid和名词evidence之间，名词evidence同时也是先行词，被which引导的定语从句修饰，空格处应填入形容词，与solid一起修饰名词evidence。根据常识可知，统计学数据对于政策制定关系很大，故此处应填入statistical。本句含义为“很难凭确凿的统计学证据证明这一现象是由于暴露在某些化学物质下引起的”。故答案为M)statistical“统计上的，统计学上的”。备选项中的形容词还剩下compact，但与上下文语义不符，故排除。
