Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. “an.”
“Soon after, they came across ____ old cottage.”
When referring to a singular countable noun that's mentioned for the first time, English uses an indefinite article ('a' or 'an') to introduce it.
The word “old” begins with a vowel sound, so the correct choice is “an old cottage”, not “a old cottage” or no article.
Using 'an' here signals that the cottage is one unspecified cottage they encountered, making the phrase grammatically correct and fluent.
