Question

Select the correct option for the blanks :
 I have _______ hour and _______ half for lunch.

Accepted Answer

The correct answer for the blanks in the sentence "I have _______ hour and _______ half for lunch." is Option 2: "an, a."

1. **Explanation for Option 2 (Correct Answer):**
   - The word "hour" begins with a vowel sound, as the "h" is silent. In English, when a word starts with a vowel sound, the indefinite article "an" is used. Therefore, "an hour" is grammatically correct.
   - The word "half" begins with a consonant sound. In English, when a word starts with a consonant sound, the indefinite article "a" is used. Therefore, "a half" is grammatically correct.
   - Thus, the sentence "I have an hour and a half for lunch." correctly uses "an" before "hour" and "a" before "half."

2. **Explanation for why other options are incorrect:**
   - **Option 1 (a, the):** 
     - "A hour" is incorrect because "hour" starts with a vowel sound, requiring "an" instead of "a."
     - "The half" is not appropriate in this context because the sentence is referring to an unspecified amount of time, not a specific half that has been previously mentioned or is known to the listener.
   
   - **Option 3 (an, an):**
     - "An hour" is correct, but "an half" is incorrect because "half" starts with a consonant sound, requiring "a" instead of "an."
   
   - **Option 4 (a, a):**
     - "A hour" is incorrect because "hour" starts with a vowel sound, requiring "an" instead of "a."
     - "A half" is correct, but the first part of the option is incorrect, making the entire option incorrect.

In conclusion, Option 2 is the only choice that correctly applies the rules of English grammar regarding the use of indefinite articles before words starting with vowel and consonant sounds.
