No one will deny that the children have worked very hard this year. (Begin: Everyone...)
Topic: Transformation — negative to affirmative
Answer
Everyone will agree that the children have worked very hard this year.
This is a DOUBLE NEGATIVE converted into an affirmative, and it requires TWO changes at once: "No one" becomes "Everyone" "deny" becomes "agree" (or "admit") Changing only one would reverse the meaning — "Everyone will deny" says the opposite of the original.
The logic: to say that NOBODY will DENY something is to say that EVERYBODY will AGREE with it. Two negatives make a positive, and the word "deny" is itself a negative verb.
The same pattern appears with other negative verbs: "No one can refuse" becomes "Everyone will accept"; "Nobody failed to notice" becomes "Everybody noticed". Whenever a negative word meets a negative verb, look for the positive statement hidden underneath.
