Answer:
4. Present progressive (he IS listening to the music)
5. Past (he LEFT it behind)
6. Past perfect. (he HAD THOUGHT he had it in his bag)
Explanation: This stuff is super simple, just think about the meanings when reading it. You can easily mark out the wrong answers here.
4. present meaning it happens now, where as present progressive is happening and will continue until the progression is over. Make sense?
5. Present or present perfect doesn't make sense here does it? no.
Just keep these in mind when taking the quiz/quick check at the end. :)
