Jose uses a more serious and professional style of speaking when he is interacting with his professors, but when he is with his friends he uses a much more relaxed style of speaking. what aspect of language is this shifting of speaking styles?

Downward and Upward Style-Shifting

Explanation:

Style-shifting refers to a language style when the speaker change their speech pattern to suit the individual they are speaking to - which can apply to social and cultural dimensions, such as age and the relationship between speakers.

We can clearly see this happening in Jose when he switches his speaking style between his professors (more formal, which is an Upward style-shifting) and between his friends (less formal, which is a Downward style-shifting).

the answer is:  

he is voicing feelings shared by all humans regardless of race.

in paul laurence dunbar's poem "we wear the mask," he replicates the words mask and we to emphasize how people in general -not just black americans- hide their true feelings. he suggests the masks cover people's faces and eyes, which are the main parts that display their emotions. he also thinks people's pain conceal behind those masks, so that they cannot see reality and nobody is able to see one another's sorrow.

the purpose of a nonfiction text is to give the text a rap up. for example, when i say : frogs are interesting animals is an ending. then when i say: frogs are unique in different ways. that is an intro.
