Read the following excerpt from an argumentative essay about why civics should be taught in schools. Answer the question that follows.

Critics might say that students should spend their school day focusing on core subjects like math, science, and language arts. A 2018 study found the opposite. According to Civics Says, an organization that promotes civics education in public schools, only one-third of elementary school students are aware of the basic structure of government. Furthermore, research shows that adding civics to other courses, like math, science, and language arts, enriches the curriculum and provides real-world examples of putting civics knowledge to good use.

What is the counterclaim the author introduces to the argument?
Civics should be taught in the classroom.
Education should focus only on math, science, and language arts.
One-third of elementary school students don't know the basics of government.
Students without civics education are actually at a disadvantage
