Fill in the blanks with appropriate articles: a, an, the.

Answer
To fill in the blanks correctly, we need to identify when to use 'a,' 'an,' and 'the.' 1. (1) a - used before 'famous institution' because 'famous' begins with a consonant sound. 2. (2) The - 'the' is used here because it specifies the school previously mentioned. 3. (3) an - 'an' is used before 'excellent' because 'excellent' starts with a vowel sound. 4. (4) an - again 'an' is used because 'old man' begins with a vowel sound. 5. (5) a - 'a' is used before 'book' since it starts with a consonant sound. 6. (6) an - 'an' is used before 'umbrella' because it begins with a vowel sound. 7. (7) a - 'a' is used because 'sun' starts with a consonant sound. 8. (8) an - here 'an' is used before 'hour' because it starts with a silent 'h', making the first sound a vowel sound. 9. (9) the - 'the' is used because it specifies the book already mentioned. 10. (10) a - 'a' is used before 'unique' because it starts with a consonant sound. Therefore, the filled-in passage is: "The United School and College is (1) a famous institution in our area.
