I don't use the word "backpack" at all;-;

Why was "There is a backpack in front of the desk" marked incorrect?

table doesn't work for 책상?

잉야기할 shouldn't be an option. You people are doing a fine job though! Tx

For 앞에, how would you differ between "in front of" and "inside"?

because I made a space between back and pack they consider it wrong

i suppose i cant say table can i? i guess in my country we're just too lazy to say desk when referring to a table used for studying
