What is one reason steinbeck uses parallelism in the grapes of wrath?

Parallel structure or parallelism means repeating the grammatical form within the sentence. Repetitive grammatical elements in the sentence are similar or identical in structure, sound, meter or meaning. This technique contributes to the balance and effectiveness of written work, affecting readability and makes texts easier to process.

For that purpose, John Steinbeck used parallelism to emphasize the injustice that occurred to migrants during the Great Depression. He wanted readers to experience the lives of migrants. In order to achieve this, he created tones of passion, sorrow, anger and despair through his writing. In order to develop his tones and present it to readers in a more acceptable and understandable way, he used paralelism.

the present continuous is a verb tense which is mainly used to indicates that an action is in progress at the moment of speaking.  

it is formed using: person + verb to be (am/is/are) +verb + - ing form  

example: i am studying at this moment .

in addition, the present continuous is also used in order to express things that will or will not happen in the near future.

example: i am having dinner with some friends tonight.

the speaker sometimes   uses it   to express that an action is repeated and it causes irritation on the part of the speaker

example: my sister is constantly complaining about everything.

most likely you should find things like facts and important information to you understand. i hope this .
