some of the questions were already inaccurate making the whole exercise pointless. Learn english

Question 7 doesn't make sense. Although I got it right, you can't say "She had never been Dubai before." There should be a "to" before "Dubai". Question 10 is incorrect. You cannot give a correct answer because no answer fits the question: "I listened the president's SONA very carefully." There should be a "to" after "listened". 15 also doesn't make much sense, as "great" is just as applicable as "wide". Additionally, it should be, "the subject, English" or "English as a subject".
