Explanation:
Let’s go step by step. You need to match each singular word (like “child”) with its plural form (like “children”) and also pick the correct rule that explains how it changed.
1. Look at “child” → plural is “children”. What changed? The “i” became “e” — that’s changing the middle vowel. So match it with “Change the middle vowel.”
2. “Tooth” → “Teeth”. Again, “oo” became “ee” — middle vowel changed.
3. “Goose” → “Geese”. Same thing — middle vowel changed.
4. “Woman” → “Women”. “a” became “e” — middle vowel changed.
5. “Foot” → “Feet”. “oo” became “ee” — middle vowel changed.
6. “Mouse” → “Mice”. “ou” became “i” — middle vowel changed.
7. “Man” → “Men”. “a” became “e” — middle vowel changed.
8. “Sheep” → “Sheep”. No letters changed — so “No change.”
9. “Fish” → “Fish”. Also no change — “No change.”
10. “Person” → “People”. Totally different word — so “Change the whole word.”
11. “Ox” → “Oxen”. Added “en” at the end — so “Add a final vowel and a consonant.”
12. “Cactus” → “Cacti”. Added “i” at the end — so “Add consonants and a vowel to the end.”
13. “Fungus” → “Fungi”. Last part “us” became “i” — so “Replace the final vowel and consonant with one vowel.”
14. “Deer” → “Deer”. No change — “No change.”
That’s all! Just match each word to its plural and the rule that fits.
