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.
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<u> "[B]ecause there was so much shouting, many of the protestors began screaming in order to be heard."</u> 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<u> "I resist the urge to stay out late and go home before midnight."</u> Here, the word resist is correctly used when the speaker states that he will try to not stay out but rather come home early.
