unit 4

Explanation:

For part B, we solve each sentence by choosing the correct word (demonstrative adjective or article) based on noun number (singular/plural) and vowel/consonant sound for articles.

1. "postcards" is plural, so "These" (demonstrative adjective for plural) is correct.
2. "opera" starts with a vowel sound, so "an" (article for vowel - initial words) is correct.
3. "photograph" is singular, so "This" (demonstrative adjective for singular) is correct.
4. "trolley" starts with a consonant sound, so "A" (article for consonant - initial words) is correct.
5. "courthouse over there" is singular and distant, so "that" (demonstrative adjective for distant singular) is correct.
6. "town's courthouse" is a specific noun, so "the" (definite article) is correct.
7. "waterway" is singular, so "This" (demonstrative adjective for singular) is correct.
8. "town library" is a specific noun, so "The" (definite article) is correct.
