MCQ with One-Line Explanations
MCQs where every correct answer comes with a crisp one-line 'why', great for self-study handouts.

✅ How to use this effectively
- 1. Fill class, board and chapter.
- 2. Choose how many MCQs you want.
- 3. Send the prompt.
- 4. Hand the explained version for self-study.
- 5. Spot-check two explanations yourself.
🔧 If it is not right, reply with this: If an explanation is too long or vague, reply: 'Make every explanation one clear line that names the key step, then re-verify the answers.'
THE PROMPT
ROLE: Act as a mathematics teacher who writes self-study MCQs with brief, clear explanations.
CONTEXT: I teach [CLASS/GRADE] for [BOARD or EXAM e.g. CBSE / ICSE / State Board / JEE / NEET]. The chapter is [CHAPTER NAME]. I want [NUMBER, e.g. 12] single-correct MCQs, each with a one-line explanation, for a self-study handout.
YOUR TASK:
1. Write [NUMBER] MCQs from the named chapter, four options A to D each, one correct, three plausible distractors.
2. For EACH question, write a single-line explanation that names the key step or idea that leads to the correct answer (not a full solution - just the deciding insight).
3. Order from easy to hard.
INPUT: Here is the sub-topic to focus on: [PASTE TOPIC OR LEAVE BLANK].
HOW TO WORK IT OUT: Solve each question fully, then VERIFY the answer by a second method before writing the one-line explanation. Make sure the explanation is true and points to the actual deciding step. Do not invent formulas. Keep maths legible.
OUTPUT FORMAT: For each question print: the question, options A to D, then 'Answer: _ - <one-line why>'. Keep each explanation under 20 words.
RULES: Exactly one correct option each. Explanations must be accurate and short. No full multi-line solutions. Difficulty suited to the class above.
FORMAT THE OUTPUT — PRIMARY DELIVERABLE:
Return the complete material as a clean, print-ready A4 handout that can be pasted into Word or Google Docs and saved as PDF. Use a clear title, logical sections, readable mathematics and page-break markers where needed. Keep student material separate from the answer key or teacher notes.
MATHS FORMATTING: Write ALL mathematics so it reads correctly in a normal chat and pastes cleanly into Word or Google Docs. Use plain readable notation - for example a/b for fractions, x^2 for powers, sqrt(x) for roots, and symbols like <=, >=, !=, +-, pi, theta, integral and sum. Do NOT output raw LaTeX or code such as \frac{}{}, \sqrt{}, x^{2}, $...$ or \( ... \) - these appear as broken symbols to a teacher in a free chat.
At the very end add a footer line: 'Prepared by [YOUR NAME]', and put 'Compiled by [YOUR NAME]' in the title block at the top.
CONTEXT CHECK: Before you begin, if any [SQUARE-BRACKET] above is still empty, or I have not given you the question / photo / data you need, ask me for exactly those and wait - never guess, and never answer with the placeholder text still in brackets.
GROUND RULES (always follow): Do not invent statistics, percentages, marks distributions you were not given, exam cut-offs, solve-time figures, NCERT or textbook page/line numbers, citations, or historical exam data. If you are unsure of any fact or number, say so and clearly label it an estimate; keep established fact separate from your own inference. Every step must be mathematically correct and at the stated class/board/exam level.
SIGNATURE: End your ENTIRE response with exactly this footer block (keep the lines and symbols):
