Questions 22 - 24. Choose A, B or C as the best answer. 22. What proportion of schools worldwide are co-educational?

BlackTom AI · Accepted Answer

Co-educational schools (boys and girls taught together) make up the majority of schools worldwide, so the correct choice is B: Most.

1) Relevant knowledge points and concepts
- Definition: co-educational = both sexes taught together; single-sex = only boys or only girls.
- Global schooling systems: public/state systems generally favor co-education for reasons of scale, equity and cost; single-sex schools tend to be a minority and are often private, religious, or selective.
- Interpretation of answer choices: "Some" implies a minority or modest proportion; "Most" implies more than half; "Nearly all" implies an overwhelming, almost universal proportion.

2) Step-by-step reasoning
- Examine global patterns: in the majority of countries the default for primary and secondary public schooling is co-education. Large public-school systems (e.g., most of Europe, North America, Latin America, large parts of Africa and Asia) operate predominantly co-educational schools.
- Identify exceptions: some countries or communities maintain a significant number of single-sex schools (certain private or religious institutions, or particular regions). Those exceptions are notable but do not outweigh the global majority.
- Compare to options: because co-educational schools are the standard across many large systems, the proportion is greater than half (so "Most" fits). However, since single-sex schools still exist in non-negligible numbers, it would be inaccurate to say "Nearly all."

3) Intermediate steps and evidence type
- No precise numeric calculation is required here; the answer depends on comparative prevalence. Observationally the number of co-educational institutions exceeds single-sex institutions in most countries, leading to a global majority.

4) Why the correct answer is correct
- "Most" accurately reflects that co-educational institutions are the prevailing model internationally while allowing for meaningful exceptions.

5) Why other options are incorrect
- "Some" understates the prevalence (implies minority).
- "Nearly all" overstates it by ignoring the substantial minority of single-sex schools in many regions.

6) Conclusion
- Therefore, the best answer is B: Most, which matches the provided correct answer.
