Scoring update (Solution 3): each line is checked as a complete “idea”.

Format rules:
• One idea per line.
• Synonyms separated by commas.
• If an idea needs two parts (paired completion), separate the parts with | (pipe). Each part must be present somewhere in the student's answer to count.

Example (SIZE):
numerator, top number | larger, increases, bigger
denominator, bottom number | stays the same, unchanged, does not change
