C. <em>The coal miner symbolizes the fossil fuel energy used to create electricity to power devices</em>. This is the correct option.
The man from the cartoon looks happy about using his device but he has a wrong idea about "green energy" since he thinks he is not using any animal fossil to power his device. His i-Pad is plugged in and the power <em>still</em> comes from a power source where a human being is hired to exploit fossil resources. If the energy had come from a true green source, the miner would not have been present. A green source could be powered by the sun or the wind.
These options are not right:
-A.The coal miner symbolizes the hard work that went into creating the internet devices we use today. ( The focus is not set on the origins of internet devices but on the way in which they are powered).
-B. The coal miner symbolizes jobs lost by books being printed online rather than on paper. ( A miner will never be related to printing books. Besides, books cannot be printed on line; they can be <em>downloaded </em>on line).
-D. The coal miner symbolizes the green energy used to create electricity that powers devices. ( A coal miner will not work at a green resource centre. Coal comes from fossils not from the sun or the wind).
