What answer?

To find the correct spelling of the plural form of the words in parentheses, follow these steps:

1. Start with the word "Ancient (Roman) used (goose) as (guard) to warn of (enemy) approaching the camp."

2. Identify the word in parentheses that needs to be made plural. In this case, there are three words: "Roman," "goose," and "guard."

3. Look up the spelling rules for making the words plural:
- For singular nouns ending in a consonant, add "-es" to make them plural.
- For singular nouns ending in "-y", change the "-y" to "-ies" to make them plural.
- For singular nouns ending in "-s", "-x", "-z", "-ch", or "-sh", add "-es" to make them plural.

4. Apply the appropriate rule to each word:
- The plural of "Roman" is "Romans" because it ends in a consonant.
- The plural of "goose" is "geese" because it follows the "-oo"-to "-ee"-rule.
- The plural of "guard" is "guards" because it ends in a consonant.

5. Replace the singular words with their plural forms in the original sentence:
"Ancient Romans used geese as guards to warn of enemy approaching the camp."

Therefore, the correct spelling of the plural form of the words in parentheses is "Romans," "geese," and "guards."
