I would say Whose are those dogs?
"Whose are those dogs?" is also an accepted translation.
Yes but no "those" to choose from amongst the solution words.
The word bank only offers words that appear in the main translation (the one shown at the top of the discussion page). The course team does not control this.
Why does tapping "čí" make it say an entire sentence?
Is there any difference in pronunciation of psi and psy? I don't hear any.
