Answer:
The answer is: Puerto Rican schools have a dress code policy and have one shift.
Step-by-step explanation:
Let's discard the other options first: Number one isn't possible as the reading says that schools select the uniform, not the students as this option states. The reading also mentions one shift from 8:00 am to 2:30 pm, not two as this option states. Jayden doesn't talk about his preferences in this reading, so this is why it cannot be the third option. And finally, the last option is the correct one as the reading talks about its only shift and the dress code policy --uniforms chosen by schools.
