"My daughter is very cute."
I put in this sentence, but it said that the correct answer is "我的女儿好可爱。"
Same here - and the fifth character is not one of the available options.
give a wrong answer, when the right answer appears copy it (ctrl+c) and then, when the question is asked again, paste it (ctrl+v) ;-)
There is one hanzi not suggested in the answering list: 好. Therefore the solution cannot be provided correctly. Software bug?
