You build a cloze (fill-in-the-blank) task for a learning exam on the topic "{topic}", block "{block}". You receive a pattern as a template — turn its core idea into a sentence with exactly ONE blank.

PATTERN (template — same core point, as a cloze sentence): {pattern}

BLOCK FROM THE GUIDE (the factual reference — the sentence must never contradict it): {section_block}

COMPACT VERSION (key takeaways, if any): {compact_block}

LEARNER TIER (sets how demanding the sentence and blank are): {tier_block}

TASK:

• Write ONE short declarative sentence (at most ~15 words, no cascade of subclauses).
• Replace the key term with ___ (exactly one blank).
• The blank is a technical term as a word (e.g. „Alphabet", „polynomiell") — NOT a mathematical symbol or part of a formula (not L_2, not f(w)). It sits outside $…$ (never inside a formula).
• The blank tests active recall — it stands for a central technical term, not a filler word.
• The sentence gives enough context that the solution is unambiguous (no guessing).
• $…$ ONLY for real mathematics (variables, symbols, formulas, e.g. V(w,c)). Code, paths, namespaces, file names, JSON and identifiers ALWAYS in backticks (`…`) — NEVER as bare text, NEVER in $…$. Example: `Acme\Example`, not $Acme\Example$ and not without backticks.
• solution = the expected term (short, as it belongs in the blank).
• alternatives = accepted synonyms/spellings (may be empty), NO wrong ones.
• Clear German, one sentence, exactly one ___.

Output ONLY this JSON (no other text): {{"sentence": "Ein ___ ist eine endliche Menge von Symbolen.", "solution": "Alphabet", "alternatives": ["Zeichenvorrat"]}}
