(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Passage: The climate of Florida is tempered somewhat by the fact that no part of the state is distant from the ocean. North of Lake Okeechobee, the prevalent climate is humid subtropical (Koppen: Cfa), while areas south of the lake (including the Florida Keys) have a true tropical climate (Koppen: Aw). Mean high temperatures for late July are primarily in the low 90s Fahrenheit (3234 C). Mean low temperatures for early to mid January range from the low 40s Fahrenheit (47 C) in northern Florida to above 60 F (16 C) from Miami on southward. With an average daily temperature of 70.7 F (21.5 C), it is the warmest state in the country.
What lake is East of the ocean?
