Read the paragraph.

people tend to adopt the style of writing and speaking that they read the most. if hours of each day are spent absorbing the casual banter of social media, the reader’s own language will reflect that casual style. if this material is balanced with more serious content, such as newspapers, journals, or classic novels, the reader’s language is likely to reflect the depth and maturity of these sources. students should strive for such balance, regularly immersing themselves in text that is more intellectual than a passing "tweet.”

what central idea is explicitly stated in the paragraph?

social media is becoming increasingly popular with students.
the language of newspapers is well researched and clever.
students’ language is a reflection of what they read.
reading is the most important subject for serious students.

The correct answer is C. Students' language is a reflection of what they read

Explanation:

According to the paragraph presented the way people write and speak is connected to the kind of texts they read. In this way formal, casual, complex or simple ways of writing and speaking are formed by the material read, an example of this is that according to the paragraph reading newspapers, journals, classic novels or similar materials would lead to developing mature and complex language and ways of speaking/writing. While social media including tweets would lead to a casual and simple way of writing and speaking. Also, the text emphasizes the importance students read complex materials (newspapers, novels, and journals) and not only social content (tweets) as the content read is reflected in their language. Thus, the central idea is that student's language is a reflection of what they read.
