【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Are you concerned about the effect of the haze(雾霾) in Singapore on the health of your children? Then you should read the following passage.
＂Young children, especially those with lung or heart illness, should avoid outdoor activity at PSI(Pollution Standards Index — used in Singapore) levels above 100,＂ says Dr Biju Thomas.
The immune system(免疫系统) of children is not mature. 16 Exposure to the haze can result in symptoms such as a blocked nose, dry throat, breathing difficulty, and so on.
Children who are exposed to the haze and experience any of these symptoms which are not serious should recover on their own in time if they limit their exposure to the haze. 17
To keep children safe during the haze in Singapore, parents should keep doors and windows closed at home. Ensure children drink plenty of pure water every day.
18 The answer is that there aren’t any N95 masks designed for use by children. That’s because these masks are made to create a seal(密封) around the mouth and nose of the adult user so particles(颗粒) can not get in. 19 Surgical masks may not offer enough protection from the harmful particles in the haze, which is very small (2.5 microns or less). There is usually some gap between the surgical mask and the face, through which the haze particles may easily get in. 20 However, if it is necessary to take children outdoors during a haze, parents may wish to offer children
A. So during a haze, children are especially at risk.
B. Are N95 masks and surgical masks suitable for children?
C. The available N95 masks may not fit tightly on the face of a child.
D. Allow children to make regular travels from one building to another.
E. However, if the symptoms continue, they should ask a doctor for help.
F. So you can use a conditioner instead of opening the windows regularly.
G. So it is best to keep children indoors to protect them from the haze when the PSI is high.
