Understanding the Arrow Notation in Organic Chemistry Elimination

[Carbon123]

Can anyone help me with this ?
What does the arrow mean ? Is it cis or trans,the base is small so it should be an E2 elimination with zaitsev product.Though I think it may be due to the beta hydrogen being unavailable,but I do not know whether the arrow means from the upper or lower /cis trans side ?

I’m assuming the arrow means that this proton is abstracted with the ethoxide base. For the product, consider two things: 1) what is the resultant species from abstracting that proton, and 2) what is its stability relative to its isomers.
