Which sentence contains an error in the wish contrast between a completed past regret and a present regret?
I wish the apartment had more natural light now.
The workshop closed permanently in October last year; I wish it stayed open until December of that year.✓Bonne réponse
I wish we had photographed the comet during Tuesday's clear spell.
If only my desk faced the window now.
Explication
The workshop sentence is erroneous because the closure happened last year, so stayed does not mark the earlier lost possibility. A past regret needs had stayed, while a present regret takes a past-simple form.
