Use the graph to answer the question.
The vertical axis ranges from 0 to 100 in increments of 10. The horizontal axis lists dates from 1776 to 2018. The data is as follows. 1776: Wood, 100%. 1801: Wood, 100%. 1826: Wood, 100%. 1851: Wood, 90%. Coal, 10%. 1876: Wood, 65%. Coal, 34%. Petroleum, 1%. 1901: Wood, 20%. Coal, 61%. Petroleum, 3%. Natural gas, 3%. Hydroelectric, 3%. 1926: Wood, 5%. Coal, 65%. Petroleum, 20%. Natural gas, 7%. Hydroelectric, 3%. 1951: Wood, 2%. Coal, 38%. Petroleum, 40%. Natural gas, 16%. Hydroelectric, 4%. 1976: Wood, 20%. Petroleum, 45%. Natural gas, 29%. Nuclear, 2%. Hydroelectric, 4%. 2001: Coal, 25%. Petroleum, 35%. Natural gas, 20%. Nuclear, 18%. Hydroelectric, 1%.

Use the scenario to answer the question.
Edwin buys a water bottle, reuses it twice, and then recycles it. Eleanor buys a water bottle, reuses it twelve times, and then throws it away.
Which energy cost would apply to Edwin, but not to Eleanor?
(1 point)
Responses
the cost of transporting the bottle to the store
the cost of transporting the bottle to the store
the cost of processing the bottle after it was no longer used
the cost of processing the bottle after it was no longer used
the cost of transporting the bottle away from the house
the cost of transporting the bottle away from the house
the cost of producing the original bottle
the cost of transporting the bottle away from the house would apply to Edwin, but not to Eleanor, since he recycles the bottle after reusing it twice.
Your class goes on a field trip to observe drilling machinery. The geologists at the drill site show you displays of drilled rocks to compare different types of drills and methods. The drilled holes in one rock display are significantly larger than the holes drilled in the display next to it. Given this information, which statement is correct? (1 point)
Responses
The rock display with larger holes shows copper drilling, which is closer to the surface.
