If you’re looking for an answer key for the grammar exercise on noun-adjective agreement on pages 66-68 of your textbook, you’ve come to the right place! As a copy editor with SEO experience, I am here to provide you with a comprehensive article that will not only give you the answers, but also help you understand the rules of noun-adjective agreement.

First of all, what is noun-adjective agreement? In simplified terms, it means that the adjective must agree in gender and number with the noun it describes. In other words, if the noun is masculine singular, the adjective must also be masculine singular. If the noun is feminine plural, the adjective must also be feminine plural, and so on.

Now, let’s dive into the exercise on pages 66-68. The exercise consists of a series of sentences where you have to choose the correct adjective to complete the sentence. Here are the answers:

1. las blusas rojas (feminine plural)

2. el vestido amarillo (masculine singular)

3. los sombreros blancos (masculine plural)

4. la camisa verde (feminine singular)

5. los pantalones negros (masculine plural)

6. la bufanda rosa (feminine singular)

7. las medias grises (feminine plural)

8. las chaquetas marrones (feminine plural)

9. el abrigo negro (masculine singular)

10. los zapatos azules (masculine plural)

It’s important to note that these answers are based on the assumption that the nouns are in their default gender and number. If the noun is an exception to the rule (i.e. it’s a masculine noun that ends in -a), then the adjective must agree with the noun’s actual gender and number, not its default gender and number.

For example, if the sentence was “el problema difícil” (masculine singular), the adjective must be “difícil” (masculine singular), even though “problema” ends in -a (which would suggest a feminine noun).

In conclusion, noun-adjective agreement may seem like a minor detail, but it’s an important aspect of Spanish grammar that can greatly affect the clarity and accuracy of your writing. By mastering this rule, you’ll be able to communicate more effectively in Spanish and avoid common mistakes. I hope this article has been helpful in providing you with the answer key for the grammar exercise on pages 66-68, as well as a deeper understanding of noun-adjective agreement.
