Select all sentences in which the tense is used correctly.
The community pool closes at eight every weekday.✓Bonne réponse
Our chef is preparing chestnut soup every winter as a regular tradition.
I am using the spare desk this week while mine is being repaired.✓Bonne réponse
The Earth is orbiting the Sun once every year.
Explication
The pool sentence correctly describes a repeated schedule, and the desk sentence correctly marks a temporary situation this week. The other forms wrongly treat a yearly routine as temporary or attach a once-every-year frequency to a continuous form.
