Correct it pls

Dear MemRise team, it’s a Great application but…
It’s uncomfortable that we can’t mark wrong(or useless) task right in application so you could improve it easily automatically or by hands. Really I don’t know why, the situation looks like 10 years ago )))

Portugues 2. topic: “Where Do You Live?”
1st picture) A girl speak Spanish or Brazilian - not Portuguese(Europian)
2nd picture) The voice in application pronounces both phrases “porque” and “por que” equally and no way which answer is correct (You forbid attach 2 images for new users! Wow!). Task is about “porque” and “por que”
