1. Which one is correct below, A mirror or THE mirror?
I watch myself in a mirror/ in the mirror every morning.
(There isn't a specific mirror. It could be a hand mirror or It could be a wall mirror. Watching myself in a mirror every morning is import.)
2. Which one is correct below, A contract or THE contract?
Are you gonna renew a contract/the contract?
(There is an employee. His contract expires in April.)
3. Is "no matter your level" correct?
(I think "no matter what your level is" is correct. But, recently, I heard a native speak say "no matter your level". Is it correct?)
Thanks in advance!
