Las casas de Puerto Rico tienen garajes que se llaman marquesinas.

Las casas de Puerto Rico se construyen de cemento.

Explanation: We must choose the sentences that are true:

1) Las casas de Puerto Rico tienen sótanos. (The houses of Puerto Rico have basements.)  

This is not really common to see, so this is no really true.

2) Las casas de Puerto Rico tienen garajes que se llaman marquesinas. (The houses of Puerto Rico have garages called canopies. )

So yes, most garajes are constructed in the form of marquesinas, that are like rooms, sometimes with no door, where you can put your car, this is true.

3) Las casas de Puerto Rico se construyen de cemento. (The houses of Puerto Rico are constructed of cement.)

This is mostly true, is an efficient and durable material, so it is used in most houses, in recent times the market of prefabricated houses raised, so you can see some houses that are of other materials, but is not the common case, the sentence is true.

4) Las casas de Puerto Rico son exactamente iguales a las casas de los Estados Unidos. (The houses of Puerto Rico are exactly the same as the houses of the United States.)

This would be false, the necessities are different, the recurses are different, and the cultures are different, of course, every house has like a kitchen, a bathroom, etc, but there are differences in other things, so the houses in Puerto Rico are not exactly equal to the houses in the US
