问题 PASSAGE TWO
What might account for some companies’ reluctance to deorbit their satellites?

选项

答案The high cost of deorbiting and lack of fair regulations．

解析第6、7段提到未来会有很多通讯公司向空间站附近的区域发射自己的商用卫星。这些卫星产生的太空垃圾会对空间站有威胁，但有些公司并没打算通过让他们的卫星脱轨来解决问题。根据第8段提到的相关法规还处于初级阶段，而“脱轨”的成本高昂，可知本题答案可归纳为The high cost of deorbiting and lackof robust regulations。
