5. how are companies responding to these changes?

Depends

Explanation:

Some/most companies do not have enough willing workers to go back into work, and so their company/ies is suffering. But some companies, like my mom and dad's, can keep working since they can manage with everyone at home. Meaning all the workers can still do all of their work from their laptop.

themselves

an intensive pronoun is a pronoun that ends in self or selves, such as himself, herself, themselves, yourself, ourselves. since band members is a third person plural, the correct intensive pronoun would be themselves. if the band was talked about as a collective noun, itself would be the appropriate intensive pronoun. intensive pronouns are used to add emphasis to the noun it's modifying which is why it directly follows it.

the author develops a cold, and scared tone. making the reader shudder with fear, and suddenly become cold. i'm guessing that he's writing a scary novel, or maybe about a chilly december night.
