本題在描述過去台灣發生的八仙塵爆（A）On June 27, 2015, at a party in a water park in Taiwan, people used the colored flour. .....描述該事故（B）問題說“該作者”“沒有”“示範給我們”，作者沒有在文章中親自示範扔有顏色的粉，When you throw it in to the air, the surface area will become larger. -->這段只是描述一個事實 （C）第一段以「But do you know that flour can blow up easily?」作為本篇文章的開場 （D）最末段-->Other powders, like sugar and milk powders are just as dangerous as flour. Be careful when you use them, and remember to keep powders away from fire.所以答案是“B”＊solving problem tips英文文章喜歡以開門見山的方式去表達自己的描述，下次遇到要問「文章主旨」的題目，可以看“第一段”及“最後一段結語”，基本上就可以找出答案了。
