The verbs that agree with the subject "everyone" are "is" and "agrees." Since "agree" is not in the correct form to match "everyone," the correct answers from your list are:
- is
- agrees (though it's not listed in your options, the correct form should be used)
However, among the options provided, if you just need to select from those available, the most fitting answer that aligns with "everyone" is "is." "Agree" does not agree with "everyone" since it should be "agrees."
If strictly selecting two from your given list that are the closest matches:
- is
- rely (if "relies" were considered because it is singular, but it needs to be "relies on" to make sense in usage).
In summary, the best answer from your list is "is" and while neither "agree" nor "were" agrees, if forced into a choice, "relies" potentially fits depending on context.
