Question

BlackTom AI · Accepted Answer

Around 95% of the world’s schools are co-educational, so the best choice is C: Nearly all.

1) Relevant knowledge points and concepts
- Definition: co-educational = boys and girls taught together in the same school/class.
- Interpretation of wording: “Some” implies a small minority, “Most” implies a majority but not overwhelming, and “Nearly all” implies an overwhelmingly large proportion (generally >90%).
- Global trend: the long-term trend has been toward mixed‑sex schooling in most countries, with single‑sex schools now a minority worldwide.

2) Step‑by‑step reasoning
- Determine what the ordinary-language choices mean quantitatively: “Some” ~ much less than 50%, “Most” ~ 50–89% (majority but not nearly universal), “Nearly all” ~ 90–100%.
- Use the given figure: about 95% of schools are co‑educational.
- Compare 95% to the categories: 95% ≥ 90% → fits “Nearly all.”

3) Calculations / intermediate steps
- Express 95% as a fraction: 95/100 = 0.95 (i.e., 95 out of every 100 schools).
- Threshold check: 0.95 ≥ 0.90, therefore it meets a “nearly all” threshold.

4) Why the correct answer is correct
- Because a proportion around 95% means that almost every school worldwide is co‑educational. That percentage is far above a simple majority, so “Nearly all” correctly describes the global situation.

5) Why the other options are incorrect
- A (Some): “Some” suggests a small minority; 95% is not a small minority, so this is wrong.
- B (Most): While “most” is true in the loose sense, it understates the scale. “Most” implies a majority but doesn’t convey the near‑universality that 95% does, so it is not the best answer.

6) Conclusion
- The correct answer is C: Nearly all, which matches the provided answer.
