9. This is something all of the schools in Spanish-speaking countries share in common:(1 point) Responses

They all learn a foreign language.
The students play at least one sport.
The students all spend at least two years in college.
All students are under the age of 13.

They all learn a foreign language.

The correct answer is: They all learn a foreign language.

To determine the correct answer, we need to consider what is commonly shared among schools in Spanish-speaking countries.

Option 1: They all learn a foreign language.
Learning a foreign language is a common practice in many schools worldwide, not just in Spanish-speaking countries. Therefore, this option may not be the specific feature that differentiates schools in Spanish-speaking countries.

Option 2: The students play at least one sport.
While physical education and sports are an integral part of many school curriculums, it is not necessarily shared by all schools in Spanish-speaking countries.

Option 3: The students all spend at least two years in college.
The statement that "students all spend at least two years in college" is not accurate for all schools in Spanish-speaking countries. College education requires higher levels of education and is not compulsory for all students.

Option 4: All students are under the age of 13.
This statement is the most specific and accurate description among the given options. In many Spanish-speaking countries, students attend primary education (elementary school) until the age of 12 or 13, which means that all students in schools share the characteristic of being under the age of 13.

Therefore, the correct answer would be: All students are under the age of 13.
