Her sister got an admission in ______ University in Germany.
The question asks us to choose the correct article ('a', 'an', 'the', or 'X' if none is needed) for the blank in the sentence: "Her sister got an admission in ______ University in Germany."
Articles are small words used before nouns. The choice between 'a' and 'an' depends on the sound that begins the word immediately following the article:
Remember, it's about the sound, not just the letter. For example, 'an hour' (h is silent, starts with vowel sound) but 'a university' (u looks like a vowel but starts with a 'y' sound, which is a consonant sound).
The word following the blank is 'University'.
Since 'University' begins with a consonant sound, the correct article to use is 'a'.
Let's complete the sentence:
"Her sister got an admission in a University in Germany."
This follows the standard grammar rule for article usage in English.
