Question

I did everything I could to persuade them to come with us, but with no success. (Begin: Nothing...)

Answer 1

HOLA friend!!
Rajdeep here.....

I did everything I could to persuade them to come with us, but with no success...

What you need to do, is to transform the above statement by beginning the statement with nothing.

So, the correct answer will be:

"Nothing did I fail to do to persuade them to come with us, but I failed."

OR

"Nothing I did could persuade them to come with us".

Hope my answer helps you....
