The correct answers are:
- is
- relies
Explanation:
- "Everyone" is a singular collective noun, so it takes singular verbs. Therefore, "is" and "relies" are the correct forms.
- The verb "think" could also be used in a singular structure ("Everyone thinks"), but since it is listed twice in your options, it doesn't count as two separate correct answers.
- "Agree" is also a singular verb ("Everyone agrees"), but like "think," it appears only once.
- "Were" is incorrect because it is a plural past form, which does not agree with the singular subject "everyone."
