b)“technology-based society”

c. get with the program

Explanation:

A "formal style" of writing uses more complex words and longer sentences in order to elaborate what the topic is all about. It is more "objective," thereby avoiding range of emotions. It doesn't involve contractions (such as "It's"), rather it uses full words.

The phrase in sentence 2 which should be revised is "get with the program." Such phrase is written in a personal tone and is colloquial in nature, thus it is informal.

Choices a, b and d are clearly written in a formal tone.

So, this explains the answer.

because of all the immigration, america became one big melting pot. the diversity of cultures from all over the world made america somewhat divided as well. people that immigrated stayed with their kind, and their traditions, while native born americans stayed with their kind and their traditions. normally, people born in american scorned the immigrants as well. the new religions also divided america. in summary, it took away from the american culture and identified america as the "melting pot."
