Answer:
Because there was so much shouting, many of the protestors began screaming in order to be heard.
I will resist the urge to stay out late and go home before midnight.
Step-by-step explanation:
First question-
Synonyms are those words that have the same meaning but might have different words. These words, though different, will still convey the same meaning. And so, the sentence that contains a pair of synonyms is the first sentence "[B]ecause there was so much shouting, many of the protestors began screaming in order to be heard." Here, the synonyms are "shouting/screaming".
Second question-
Based on the definition of the word "resist" given in the question, the sentence that uses the word correctly is the last/ fourth option "I resist the urge to stay out late and go home before midnight." Here, the word resist is correctly used when the speaker states that he will try to not stay out but rather come home early.
