Wouldn't E also be possible? I mean the solvent is not specified so the reaction could go E1 or E2 since both can react with tertiary halides? Can someone shine some light on this for me? Thanks!

The best reagent is the one that inhibits E1/SN1...so we want a strong base.

so in cases like this E2 is preferred over E1?

Just out of curiosity, if this reaction was to proceed via E1, would the carbocation shift to the left to be allylic to the benzene ring?

Either way, I see Eugeniager's point...either E1 or E2 would give the same major product here. Is there a specific reason we would want to go E2?

yeah that's what I am confused about..hope flavor will comment further on this. i guess what he means is that E2 or preferred over E1? 😕

E1 also gets you SN1 products. E2 will not also get you sn2 products because it's a tertiary carbon/hindered.
