6-2-4-5-1-3

Answer

B. 6-2-4-5-3-1

Solution

The correct order is 6-2-4-5-3-1. Each sentence picks up an idea from the one before it: Old phones and computers are often thrown out with ordinary household garbage. Such electronic waste contains small amounts of valuable metals, including gold and copper. It also contains toxic substances such as lead and mercury. When e-waste is burned or dumped carelessly, these toxins can leak into soil and water. Proper recycling, by contrast, recovers the metals while keeping the toxins contained. Some malls and telecom companies now operate drop-off points to make such recycling easier. Each wrong choice swaps just one pair of neighboring sentences, which breaks one of these links.
