For the exercises where I am asked to choose 1 of 4 words to fill the space, it would be good to hear the sentence after I have chosen the answer. I'm not sure where to put that request, as it isn't really a fault that I can report. If someone on the Hindi development team reads this - please add sound for the sentences after we have chosen the answer.
