What' wrong with " there is a gum in my bag "?
Actually your answer is correct and Duolingo is wrong.
Assuming that it means "chewing gum," and not a single gumdrop candy, I've never heard it said that way. You could say "there is some gum in my bag," or "there is a pack of gum in my bag," but I don't think "a gum" is correct English grammar.
Yje worst is that "the English sentence is wrong" is not even among the possibles error flags...
Can someone identify the first two letters in the word for gum.
I don't hear the "L" (second letter)
hmm ..it's ok with me (i'm on PC and use speakers)
