- D datas

✔ Correct Answer: B) data

2. Write the plural form of the given noun.
basis – ________

"Basis" ends in "-is", which is a common Latin-derived ending. The plural of such nouns typically changes to "-es", so:

3. Which nouns have the correct plural forms? Check all that apply.

- A grandchilds
- B firemen
- C passersby
- D bookshelves

✔ Correct Answers: B, C, D

Explanation:

- A) grandchilds ✘ Incorrect. The correct plural is grandchildren.
- B) firemen ✔ Correct. This is an irregular plural (man → men), so "fireman" becomes firemen.
- C) passersby ✔ Correct. "Passerby" becomes passersby (plural without adding 's').
- D) bookshelves ✔ Correct. Regular plural: add -s to "bookshelf".

4. Which is the plural form of the given noun?
Cruz – ________

- A Cruz's
- B Cruzes
- C Cruzs
- D Cruz’s

✔ Correct Answer: B) Cruzes

Explanation:
"Cruz" is a proper noun (a surname). For surnames ending in consonants, we usually form the plural by adding -es. So:
- Cruz → Cruzes

Note: "Cruz's" (A or D) is possessive form (e.g., "Cruz's car"), not plural. "Cruzs" (C) is incorrect because it doesn't follow standard pluralization rules for names like this.

5. Which nouns have the correct plural forms? Check all that apply.

- A 2020s
- B DOHs
- C Bs
- D t’s

✔ Correct Answers: A, B, C

Explanation:

- A) 2020s ✔ Correct. When pluralizing years, we add 's after the number: 2020s.
- B) DOHs ✔ Correct. Acronyms often take an 's for plural: DOH → DOHs (e.g., Department of Health).
- C) Bs ✔ Correct. Letters are pluralized by adding 's: B → Bs.
- D) t’s ✘ Incorrect. The correct plural of "t" is Ts (without apostrophe). Apostrophes are only used for possession or contractions, not plurals.

So, Ts is correct; t’s is wrong.

6. Write the plural of the singular nouns inside the parenthesis.
The desert is home to many ____________. (cactus)

✔ Answer: cacti

Explanation:
"Cactus" is a Latin word. Its plural is cacti (from Latin *cactus* → *cacti*).

So: "The desert is home to many cacti."

Five ____________ grazed in my backyard. (deer)

✔ Answer: deer

Explanation:
"Deer" is a noun that has the same form in both singular and plural. It is an irregular noun.

So:
- One deer
- Five deer

This applies to other animals like "sheep", "fish" (in some contexts), etc.

✔ Answer: mangoes or mangos

Explanation:
"Mango" can be pluralized in two ways:

Both are acceptable, but mangoes is more widely accepted in formal writing.

So: "We saw many mangoes in the park."
