"They have two sons."
Translation:उनके दो बेटे हैं।
I can't for the life of me figure out why this answer is wrong: उनके दाे वेटे हैं. I get marked incorrect every time, even though, as far as I can tell, it is correct. I am going to have to resort to the word bank to finish the exercise, but I would truly like to know whether I have done something incorrectly or whether there is a bug in the system somewhere.
I got this wrong several times with "do" underlined. Despite being visually identical, it wants you to type it as "d" + "o" rather than as "d" + "a" + "`."
Sorry for not typing in Hindi. I have Duo keyboard set up, but I'm not yet familiar with the Microsoft IME for Hindi and don't know how to type it out on there.
