11. I heard a pack of ________ howling loudly in the forest. (wolff)

12. The farmer's ________ walked slowly into the field. (sheep)
→ "Sheep" is the same in singular and plural → but "walked" (past tense) suggests more than one → plural
Answer: *sheep*
*(Note: "sheep" is irregular — same for singular and plural)*

13. The young ________ peered at the players. (potato)
→ "The young..." likely refers to one person (a child), not potatoes → probably a typo? But if we assume it’s about a person, then maybe "potato" is meant as metaphorical? Wait — that doesn’t make sense.
Actually, let’s re-read: “The young ________” — perhaps it's "potato" meaning a young person? That seems odd.
Alternatively, could it be a typo for "peasant" or "boy"? But since the word is given as (potato), and "potato" is not typically used for people...
Hmm — unless it's a joke or metaphor? But likely, it's a mistake.
However, assuming the intended meaning is "the young potato", which doesn't make sense.
Wait — perhaps it's "the young lady"? No — the clue says "(potato)".
Another possibility: maybe it's "the young potato" as in a baby plant? But "peered" suggests a human-like action.
This seems like an error. But perhaps it's supposed to be "the young boy" or something else.
Let’s reconsider: maybe the word is "potato" and we’re to use its plural?
But "the young potato" → singular. "Peered" is singular verb → so likely singular.
So: Answer: *potato*
*(But this sentence is awkward — possibly a typo in the original. If it were "young men", it would make more sense. But we must go by what's given.)*

✔ Final decision: Since the verb is "peered" (singular), the subject must be singular → potato

14. The caterpillars suddenly turned into stunning ________. (butterfly)
→ "Caterpillars" = plural → so they turn into multiple butterflies → plural
Answer: *butterflies*

15. There were high ________ and beautiful ________. (cliff, valley)
→ "Were" = plural → both nouns need to be plural
Answer: *cliffs*, *valleys*

16. The ________ have four ________. (buffalo, foot)
→ "Have" = plural verb → subject is plural → buffaloes or buffalo (both acceptable; "buffalo" can be plural)
And "four" → feet (plural of foot)
Answer: *buffalo*, *feet*

17. The rotten ________ stole the bright red ________. (thief, cherry)
→ "The rotten..." = one thief → singular
"Stole" = past tense, singular or plural — but "stole" is consistent with singular or plural.
But "the bright red ________" — likely one cherry? Or more?
"Stole" could be singular or plural. But "the bright red cherry" makes sense as singular.
However, "the rotten thief" → singular
So: thief, cherry
Answer: *thief*, *cherry*

18. Those ________ had to do many ________. (boy, quiz)
→ "Those" = plural → boys
"Many" → plural → quizzes
Answer: *boys*, *quizzes*

19. The ________ played happily among the ________. (fox, cactus)
→ "Played" = plural verb → subject is plural → foxes
"Among the..." → plural → cacti or cactuses (both acceptable)
Answer: *foxes*, *cacti* (or *cactuses*)

20. The ________ had fun at the spring ________. (elf, party)
→ "The ________" — likely elves (plural) because "had" is plural
"Spring party" — one party → party
Answer: *elves*, *party*

📌 Notes:

- Some words are irregular plurals (e.g., child → children, mouse → mice, tooth → teeth).
- Context (numbers, verbs, determiners like "those", "many") helps decide singular vs. plural.
- Sentence 13 ("The young potato") is unusual — likely a typo or metaphor, but based on grammar, we go with singular.
