Which one of the following statements best reflects the central idea of the passage given above?
Answer & explanation
Answer: (b) Availability of higher education can be made easier and cheaper without diluting the content.
The best universities pair video lectures with active class discussion, give those lectures free to the world, and invite other colleges to build them into their own teaching. The central idea is that good higher education can reach more people, more cheaply, without losing quality.
- ✗ (a) The passage describes a blended 'flipped classroom', with class time and professors, not a claim that online mode beats conventional teaching.
- ✓ (b) Lectures by excellent teachers are 'available free for anyone in the world' and can be integrated by colleges everywhere — easier, cheaper access to the same content.
- ✗ (c) Infrastructure spending is never discussed, and 'human and social capital' is a leap.
- ✗ (d) Private institutions and coaching institutes are not mentioned.
Remember · The central idea generalises what the passage's examples achieve; reject options about groups or costs the passage never mentions.
