A, B, C, and D

Answer 1

The best option that shows ways the increased use of copper affects Earth itself is A and D.

• A states that the amount of available copper ore decreases, which reflects the depletion of resources due to increased mining.
• D indicates that pollution from mining increases, pointing out the environmental impact of extracting more copper.

While options B and C also relate to the consequences of increased copper use, they are more about market dynamics and behavioral changes rather than direct effects on Earth itself. Therefore, the correct response is A and D.

Answer 2

And you are sure?

Answer 3

Yes, I am confident in that response.

• A (The amount of available copper ore decreases) directly relates to the depletion of a natural resource, which is an environmental impact of increased copper usage.
• D (Pollution from mining increases) highlights the environmental consequences associated with the extraction process.

Both A and D focus on specific effects that increased copper use has on Earth, while B and C relate to economic factors and social behavior rather than direct effects on the environment. Thus, the best choice is indeed A and D.
