• B. after I have finished my homework
• C. as soon as you arrive home
• D. before the Prime Minister enters the conference hall

Answer 1

The correct option is A when the eight o'clock news started

Option A is the correct answer. It serves as the most appropriate timing in relation the the event described in the sentence. Options B and C are incorrect because they are not compatible with the tense in the first part of the sentence. Where the given part is in the past tense, option B is in the present perfect tense and option C in the simple present tense. Option D is also incorrect in the given context because it has no relation to the lights going out.
