Answer: A storm caused a power failure, so Peter started the new generator.
A computer virus has totally wiped out my had drive because I did not renew my subscription to my virus protection program
Explanation: for the first statement, the main clause is 'A power failure' as it is drawing attention to the action carried out by Peter. Joining the 2 statements was only possible if 'so' is added, as it shows exactly the reason why Peter started the new generator.
For the second statement, computer virus is the main clause. 'because' is a word showing what had caused an event to occur, so it is the best joiner for the 2nd question
Answer:
Peter started the new generator when a storm caused a power failure.
Because I did not renew my subscription to my virus protection program,a computer virus has totally wiped out my hard drive.
Explanation: In the first sentence, the adverbial clause of time comes after the main clause. That is, telling us what Peter did after the storm has caused power failure.
In the second sentence, the adverbial clause of reason tells us why the computer virus wiped out the hard drive.
