You know, it's kind of funny that the word 'difficulties' is such a hard word. Just try and pronounce it...
"There are still many vans skidding down hills," she explained candidly. "But nothing we can't handle. We can count them!"
Why is this wrong
there still are many difficulties
It doesn't say that it's wrong. I was thinking "There are still many obstacles," as that seems to make better sense, which is easier to follow with "but nothing we can't handle"
It very much says that's wrong, even though it most definitely is not.
It doesn't accept "constantly". According to the dictionary that is one meaning of "stadig"
It wouldn't be the right choice in this sentence. The "stadig" here implies that there was an expectation that the difficulties would have lessened or disappeared, but has not.
