Which sentence has a hyphen where it should not be?
The custom-built computers were an instant hit among buyers.
Agents were sent to his house to re-cover the money.
Two-thirds of the cake was reserved for my friends.
He is the most well-known stock analyst in New York.
The correct answer would be option B. Agents were sent to his house to re-cover the money. This sentence uses hyphen incorrectly because the word "recover" should only be one word. Words that are connected by hyphens are only compound words.
