Question

"you are a very gallant young man",she said,"but why are you so serious?" change of voice

Answer 1

she said that he was a very gallant young man but why he was so serious

Answer 2

We need to change the voice of the statement given in the question.

• We need to change the voice by making it into a passive voice from the active voice in which the sentence is.  

• She said that he was a very gallant young man and further asked why he was so serious
• The active voice of the second person has been changed to the passive voice in the third person.
• Also in such cases, the tense of the sentence changes to the past tense.
• The passive voice is used and it shows interest in the person or object  who experiences an action rather than the person who experiences that action
• In other words, we can say that the most important thing or person becomes the subject of the sentence.
