The correct answer is 4. Reflexive writing is used by accomplished writers, while extensive writing is used by beginning writers.
Step-by-step explanation:
Extensive and reflexive writing are two types of writings that differ in their purpose and features. In the case of extensive writing, in this novice writers write long texts about any topic mainly for purpose and without following high standards for writing. On the opposite, reflexive writing is mainly used for more skilled writers because this aims at creating formal texts about any topic but including a reflection which requires more knowledge and practice than in the case of extensive writing. Considering this, the difference between reflexive and extensive writing is that "Reflexive writing is used by accomplished writers, while extensive writing is used by beginning writers".
