Example: Quantum Entanglement Explanation

PROMPT:
Explain quantum entanglement to a 12-year-old in under 150 words.
RESPONSE A:
Imagine you have two magic dice. When you roll one in New York and the other in Tokyo, they always land on the same number, even though nobody looks until the last moment. In quantum physics, particles can be 'entangled' so their properties are linked this way. No messages travel between them; it's just how the math works. Einstein called it 'spooky action at a distance,' but experiments show it's real!
RESPONSE B:
Quantum entanglement is when wave-functions of multipartite Hilbert spaces non-locally collapse, violating classical separability axioms, so the Bell inequality is transcended in an SU(2) singlet.
Preferred: Response A
ANNOTATION:
A is age-appropriate (grade-7 reading level, 112 words) and accurate. B uses jargon a 12-year-old would not grasp.

Example: Merge Sort Bug Detection

SUBMISSION ID:
code_11402
CODE:
def merge_sort(arr): # BUG: this incorrectly recurses when array length is 1 mid = len(arr) // 2 left = merge_sort(arr[:mid]) right = merge_sort(arr[mid:]) return merge(left, right)
EVALUATION RESULTS:
  • Compiles: ✓ Yes
  • Unit Tests Passed: 0 / 12
  • Quality Score: 0.17
ISSUES FOUND:
  • Infinite Recursion (Line 4) Base case missing when len(arr) <= 1
  • Performance Issue Slices create O(n log n) additional arrays
SUGGESTED FIX:
Add if len(arr) <= 1: return arr guard

Example: Medical Expert Q&A

QUESTION ID:
endo_00294
QUESTION:
For a 58-year-old patient newly diagnosed with type 2 diabetes and stage 2 chronic kidney disease, what is the ADA-recommended first-line medication and typical starting dose?
ANSWER:
Metformin 500 mg orally twice daily with meals.
CHAIN OF THOUGHT:
  • ADA 2024 guidelines recommend metformin unless eGFR < 30 mL/min.
  • Patient has stage 2 CKD (eGFR 60–89), so metformin is safe.
  • Start low (500 mg BID) to minimise GI side-effects; titrate every 1–2 weeks.

Example: Team Meeting Diarization

AUDIO FILE:
team_meeting_clip.wav (Duration: 00:31)
SPEAKER DIARIZATION:
  • 00:00 - 03:54 → Speaker A
  • 03:54 - 06:80 → Speaker B
  • 06:50 - 08:80 → Overlap (Speakers A & B)
TRANSCRIPT:
  • [00:00-03:54] Speaker A: "Alright, let's review the sprint backlog..."
  • [03:54-06:50] Speaker B: "Sure, first item is refactoring the data loader."
  • [06:50-08:80] Speaker A: "Exactly, we'll need benchmark results by Friday."
ASR METADATA:
  • Utterance ID: tmc_0007
  • Language: English
  • Pronunciation Quality: 0.94
  • Note: Minor clipping on 'benchmark'
