If you would have
gone to his house
before 10 a.m., you would have
got his autograph E. No error
Answer is Right!
Answer is Wrong!
The correct answer is: E. No error
The sentence is grammatically correct. The use of the past perfect subjunctive “would have gone” and the past perfect infinitive “to have got” is correct to express a counterfactual situation, i.e., a situation that did not happen but could have happened.
The sentence can be paraphrased as follows: “If you had gone to his house before 10 a.m., you would have got his autograph.”
