With the info provided, I call this exhibit one why ochem gets a bad reputation. If this were an alkene reaction, the product would be an alcohol. One generally doesn't indicate aqueous acid for dehydration/elimination. If you do, expect confusion, in my opinion.
I might expect formation of an allylic carbocation, but in water, it should add water back to it. No net reaction. The only other reaction I might think of is a neighboring group addition of water to the alkene. Were reactions of this type given in class or problems? If so, I might expect a three-membered ring intermediate. Opening of this ring would give a trans-1,2-diol.
