The answers are:
"las leyes federales de los Estados Unidos" --> "the federal laws of the United States"
y --> and
"las leyes estatales de Puerto Rico" --> "the state laws of Puerto Rico"
The following is a section from my lesson:
Puerto Rico is an island in the Caribbean. Although it's often referred to as a country, it's actually a territory that belongs to the United States (U.S.). Puerto Rico is slightly different from most of the U.S. territories because it's a commonwealth like the Northern Mariana Islands.
This status means that Puerto Rico is considered a self-governing unit that's willingly associated with the U.S. Therefore, the federal laws that apply in the 50 states apply in Puerto Rico, and it aso has the freedom to self-govern like the states.
Puerto Rico has its own constitution, and its people are U.S. citizens who get a social security number at birth and who can freely travel to and from the U.S. However, they're also citizens of Puerto Rico. Remember, for legal, travel, and communication purposes, Puerto Rico is generally treated the same as a state by the postal services, retail companies, airlines, and U.S. government. So, if you want to take a vacation from the U.S. and don't have a passport, you can travel to Puerto Rico and even take the family pet.
