Which sentence is accurate? Do you know what she did ? I believe this is the right one its pertains to something that someone done in the past.
Do you know what did she do?I believe its not correct it's gramatically incorrect mixing past and present tense are not cool

Hi,

mixing past and present tense are not cool

You don't think it's correct to say I know Obama won a Nobel Prize this year ?
