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 boys", it would make more sense. But based on the clue, we go with "potato")*

✔ Final Answer: potato (singular)

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

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

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

17. The rotten ________ stole the bright red ________. (thief, cherry)
→ "The rotten" → singular → thief
"Stole" → past tense, singular → thief
"The bright red" → one cherry → 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 → foxes
"Among the" → plural → cacti or cactuses (both acceptable; "cacti" is Latin plural)
Answer: *foxes, cacti*
*(Or "cactuses" — both are correct)*

20. The ________ had fun at the spring ________. (elf, party)
→ "The" → could be singular or plural, but "had" → past tense, singular or plural?
"Had" is used for both singular and plural → but "spring party" is one event → likely one elf?
But "the" might refer to a group.
However, "the elf" → singular → "had" is okay for singular
"Spring party" → one → party
But could also be plural: "elves" and "parties"?
But "the spring party" → likely one party → so party
But "the elves" → plural → "had" works
Let's look: "The ________ had fun" → could be either
But "spring ________" → likely party → singular
So probably: elf, party
But could also be elves, party
However, the structure is: "The [blank] had fun at the spring [blank]"
If it's one elf → "The elf had fun at the spring party" → makes sense
If it's multiple elves → "The elves had fun at the spring party" → also makes sense
But "spring party" is singular → so second blank is party
First blank: could be singular or plural
But "the" + noun → no clear indicator
But since it's a single event ("spring party"), and "had fun" — both forms are grammatically correct
But looking at the pattern of the worksheet — often uses plural for groups
But here, "the" is ambiguous
However, since "party" is singular, and "had" is shared, it's safer to assume singular
But actually, "elves" is fine too
But the most natural is: elf, party
Or elves, party
But the answer key likely expects elf, party — unless specified otherwise
Let's check: "The elves had fun at the spring party" — very common
So plural is possible
But without more context, both are valid
But since the first blank is before "had", and "had" can be plural, we need to decide
But "the" doesn't help
However, in such exercises, if no number is given, and the verb is "had", it could be either
But let’s see: "The elf had fun" vs "The elves had fun" — both work
But "spring party" is singular → so second blank is party
First blank: depends on what the writer wants
But since the word is given as (elf), and we're to choose singular or plural, and there's no indication of number, but "the" + "had" → could be either
However, in most such worksheets, if it's one person, they say "the elf", if many, "the elves"
But here, no clue
But "spring party" is singular → so likely one event
But doesn't tell us how many elves
So safest: assume singular
But actually, in real usage, "The elves had fun at the spring party" is more common
But since the word is (elf), and only one is listed, maybe singular
But wait — the instruction is to fill in the blank using the word in parentheses, choosing singular or plural
So we can use elf or elves
But the clue is "elf" → so we can make it plural
Since "had" is plural-compatible, and "spring party" is singular, the best choice is:
elves, party — because "elves" is plural, "had" matches, "party" is singular
But "the elves" → plural subject → "had" → correct
So: elves, party
✔ Answer: *elves, party*

📝 Summary Notes:

- Many of these words are irregular plurals (e.g., child → children, mouse → mice, man → men).
- Some words have the same form for singular and plural (e.g., sheep, fish, buffalo).
- Always pay attention to context clues: numbers ("two", "three"), verbs ("were", "had"), and collective nouns ("flock", "pack").
