Practice Listening: Multiple Choice, Single Answer ID: #41022 Short Aluminium
Instructions ›
You will see a video about the process of recycling aluminium cans. Listen to the recording and answer the multiple-choice question by selecting the correct response. Only one response is correct.

Transcript:

Many waste materials are recyclable, including aluminium cans and paper. These materials must be processed before they can be reused as raw materials for new products. Processing aluminium cans begins at the recycling centre, where clean, dry aluminium cans are either compacted into bales or shredded into popcorn-sized pieces of metal that are blown into a trailer. The aluminium is then shipped to a processing facility. There, the baled or shredded cans are melted in an industrial furnace. The furnace burns off any labels or inside coating on the cans. The molten aluminium is cast into blocks called ingots and, while still hot, rolled into sheets for new cans. Aluminium cans can be endlessly remelted and reused.

Option 4: "They are compacted into bales or shredded into small pieces."

Explanation: This option accurately reflects the information in the text, which states that at the recycling centre, clean, dry aluminium cans are either compacted into bales or shredded into small pieces before being shipped for further processing.

Option 1: "They are cleaned with a chemical solution."

Explanation: The text does not mention any cleaning process involving a chemical solution at the recycling centre. Instead, it states that clean, dry aluminium cans are processed, implying they must be clean before arriving, but no specific cleaning method is described.

Option 2: "They are separated based on colour and size."

Explanation: The text does not indicate that aluminium cans are separated by colour or size at the recycling centre. It focuses on the processes of compacting or shredding, making this option incorrect.

Option 3: "They are immediately melted down."

Explanation: The text clearly states that aluminium cans are first compacted into bales or shredded before being shipped to a processing facility for melting. Therefore, this option misrepresents the sequence of events.
