This answer appears in the writing challemge: "Pre-date stress".

The question was "All afternoon, he'd rehearsed in his head"

Why would the answer not end in "la tête"? Or at least allow both la and sa?

Isn't this a similar case to "il s'est gratté la tête" (He scatched his head) where the body part belongs to the subject of the verb.

In the B2 writing challenge "Pre-date stress"

"he'd taken out the garbage"
is translated

"il avait sorti les poubelles"

but isn't this just as valid:

"il a sorti les déchets"

The first assumes that the person is taking a trash can out (to the street) but the second (describing the situation in my house) assumes the person is taking (bagged) garbage out to the trash can.

If so shouldn't the excercise be updated?
