Bonjour:)

1. Correction en piece-jointe

2. e. Who visited him yesterday?

What is the difference with the questions a,b,c and d = there is no auxiliary.

The subject is “who”

When the missing information is the subject of the question we don’t need an auxiliary.

3.

f. When did you see the victim for the last time ?

g. Does he look worried ?

h. Why does his son has a different name ?

g. Who found the victim’s body ?
