Social Science (087) — AI-generated practice question

Magnetite has a very high iron content (up to 70%) and excellent magnetic properties, making it the finest in quality. However, hematite is the most important industrial iron ore because of the far greater quantity in which it is available and used, even though its iron content is slightly lower (50–60%). Industrial importance depends not just on quality but on availability and volume of use. Thus, magnetite is superior in grade, but hematite dominates actual industrial production.

• The key distinction examiners expect is quality vs. quantity/availability.
• Mention the iron percentages: magnetite (up to 70%), hematite (50–60%) — figures show you've read the source.
• The word "industrially" in the question signals that quantity used is the deciding factor, not purity alone.
• Avoid writing a lengthy essay; 3 marks = ~3 clear points, which this answer covers: magnetite's quality, hematite's dominance by quantity, and the reason for the apparent contradiction.
