Homeowners often weatherize their homes, that is, they add insulation and seal up gaps to avoid drafts. In the past, many homeowners used insulation that releases formaldehyde, a gas that at high concentrations causes health problems. Such insulation is now banned. It is still possible, however, to create dangerous levels of formaldehyde by weatherizing a house, since reducing airflow increases the concentrations of any gas being released into the air of the house, and________.
Which of the following most logically completes the argument?
选项
A、any formaldehyde-releasing insulation installed before the ban has long since stopped releasing formaldehyde
B、many items in a typical home release measurable quantities of formaldehyde
C、the insulation that releases formaldehyde was easy to install in an existing house
D、almost all of the fresh air that enters a weatherized house enters through heating and cooling vents
E、certain other kinds of insulation present other health risks if not used properly
答案
B
解析
即使隔热物释放的甲醛不存在了,但是其他东西依然会释放甲醛,加上原文提到的减少空气流动会导致气体浓度升高,可知该项能够解释文章,B正确。A项隔热物早就停止释放甲醛,无法解释为什么现在的甲醛浓度依然有可能升高。C项和是否容易安装无关,不选。D项新鲜空气来自哪里,和本文讨论内容无关,不选。E项文中只是讨论甲醛,和其他健康问题无关,不选。
