So the response I get when I try the above answer is that the C–Br bond is replaced with a C–O bond, but it asks me where the O must come from in the EtOH. Which of the two bonds to O is more likely to break when the O in EtOH makes a new bond? Please show the correct answer.

This is an elimination reaction and the product we expect is an alkene, in this case the only alkene that can be formed is that with a double bond between the benzyl carbon (the carbon that is directly bonded to the benzene group) and any of the two methyl groups.
The reaction will most likely follow the E1 reaction mechanism because the tertiary phenyl-conjugate carbocation that is formed in the first step is very stable. On a second step, the Br– that is released grabs a -H from any of the -CH3 groups and the double bond is formed:
