About half of the world's zinc production is used for what purpose?
AMaking decorative jewelry and ornaments
BManufacturing glass and ceramic products
CProtecting iron and other metals from corrosion
DProducing agricultural fertilizers and pesticides
Answer & Solution
Correct answer: C. Protecting iron and other metals from corrosion
1. Zinc is widely used in coatings applied to other, more corrosion-prone metals.
2. The text states: "About half of zinc production serves to protect iron and other metals from corrosion."
3. This corrosion-protection role (galvanizing) is the dominant industrial use described, not jewelry, glass, or fertilizer manufacture.
4. So the largest single use of zinc, by the text's account, is protecting iron and other metals from corrosion.
