To determine the correct answer, let's analyze the given options:
A:
used to
B:
should
C:
ought to
D:
would
The correct answer is A, "used to". Here's why:
1.
Used to: This phrase is used to express something that was true or happened in the past but is not true or does not happen now. In this sentence, it indicates that there was a famous shop in the past, but it may no longer exist.
2.
Should: This modal verb is used to express obligation, recommendation, or expectation. It does not fit the context of the sentence, as it does not imply anything about the existence of a famous shop.
3.
Ought to: Similar to "should", "ought to" expresses obligation or recommendation. However, it does not indicate anything about the existence of a famous shop.
4.
Would: This modal verb is often used to express conditional situations or hypothetical scenarios. It does not fit the context of the sentence, as it does not convey any information about the existence of a famous shop.
In conclusion, the correct answer is A, "used to", as it accurately reflects the idea that there was a famous shop in the past, but it may no longer be present.
