Can you check this question and answer?(I need to shorten the answer: points 2-3)
1) Describe the kind of technique adopted by writers (at the beginning of the 20th century OR by early 20th century writers) to represent the unspoken activity of the mind.
2) At the beginning of the 20th century, writers gave more and more importance to subjective consciousness and understood it was impossible t reproduce the complexity of the human mind using traditional techniques; so they looked for more suitable means of expression.
3) They adopted the interior monologue to represent, in a novel, the unspoken activity of the mind before it is ordered in speech.
1. Either phrasing works, but I think the second one is better.
2. Alternative for you, although it's not shorter!
In the early 20th century, writers gave more importance to expressing human thoughts than they had in the past. They understood it was impossible to reproduce the complexity of human thought by traditional techniques; therefore, they tried out different means of expressing this.
3. OK
1) The technique adopted by writers at the beginning of the 20th century to represent the unspoken activity of the mind is called the interior monologue.
2) At that time, writers recognized the significance of subjective consciousness and realized that traditional techniques were insufficient to portray the intricate workings of the human mind. Therefore, they sought alternative ways to effectively express it.
3) In order to capture the unspoken activity of the mind before it is organized into coherent speech, these writers employed the interior monologue in their novels.
