Choose the pair of words from the options provided that correctly fills the blanks to complete the sentence.

________________________ was the orator's strength, and he relied on this passion to ________________ the crowd into supporting the cause.

Correct Answer: Fervor, persuade

To determine the correct pair of words to fill in the blanks, let us analyze the context and meaning of the sentence step-by-step:

1. Analyzing the First Blank:
The sentence mentions that the missing word "was the orator's strength, and he relied on this passion...". The word "passion" directly refers back to the noun placed in the first blank. Therefore, we need a word that means intense passion, zeal, or enthusiasm.
• Fervor means intense and passionate feeling, which aligns perfectly with "passion".

2. Analyzing the Second Blank:
The second part of the sentence reads "...to ________________ the crowd into supporting the cause." An orator using passion or fervor aims to convince or influence an audience.
• Persuade means to induce someone to do something through reasoning or argument/emotion, which fits the context of inspiring the crowd to support a cause.

3. Evaluating Other Options:
• toxicity, nurture: "Toxicity" (poisonous nature) does not mean passion, and "nurture" does not fit influencing a crowd to support a cause.
• compulsory, compel: "Compulsory" is an adjective meaning mandatory, not a noun representing a strength or passion.
• supremacy, extract: "Supremacy" means state of being supreme, not passion.
• freedom, urge: While "urge" could work for the second blank, "freedom" does not synonymously match the referenced "passion" in the sentence structure.

Thus, the correct pair of words that logically completes the sentence is Fervor, persuade.
