38: The market for recycled commodities like aluminum and other metals remain strong despite economic changes in the recycling industry.
- commodities like aluminum and other metals remain
- commodities like those of aluminum and other metals are remaining
- commodities such as aluminum and other metals remains
- commodities, such as aluminum and other metals, remain
- commodities, like the commodities of aluminum and other metals, remains
为什么不能选a??? 还有c中用了同位语,我想问,同位语修饰对象是前一部分中心词(这里应该是market) 还是靠他最近的那个(这里就是commodities)?
请指教!!!
