Answer 1

$\mathbb{ \huge{ \fcolorbox{blue}{pink}{Answer!!}}}$

$<b>When did you do this?$

$\huge{Explanation:}$

$<b><i>✨The sentence which you gave is in Passive voice,so by the rules the answer which I gave you is in the Active.$

✨As you can see,there is no doer present in the original sentence.So,we have to assume one.

✨If we add a doer in the original sentence,then it becomes "By when was this done BY YOU".If we convert this sentence to the active voice,we get "When did you do this?" which is the answer.

✨In these types of sentences,imagining a doer is the most important thing of changing the voice.You can also take the doer as 'you','they','she','he'.ect.

✨But remember,never use a doer which is in the first person.Always imagine a doer which is in the second or third person.

DOER=The person who has done the work.
