I have a doubt on the following question.
1) I ______________ want to be a practising doctor but now I'm more interested in research.
A. was used to
B. used to
I was going with would but the correct answer is used to.
1.We use used to + infinitive to talk about permanent situations that are usually no longer true.
2. We do not use used to if we want to talk about how long the situation lasted.
Reference: Cambridge Grammar for IELTS
Now although I read this two tips, but still this answer is not clear to me. Is this question related to any permanent situation?
I still don't understand the reason behind the choice used to, rather than would.
