Choose the correct item. this/these frog is green but that/those frog is brown/ that/those ducks are yellow.

Here is the breakdown of the correct grammatical choices for your sentences. Correct Sentences

1. This frog is green but that frog is brown.
2. Those ducks are yellow.

Grammar Explanation In English, demonstrative pronouns (this, that, these, those) must match the number (singular or plural) of the noun they describe.

Why these choices were made:

• This/That frog: The word "frog" is singular (one frog). Therefore, you must use the singular forms this or that. Using "these" or "those" would be incorrect because they require the plural "frogs."
• Those ducks: The word "ducks" is plural (more than one). Therefore, you must use the plural form those. Additionally, the verb "are" confirms that the subject is plural.
