This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(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.

Input: Consider Input: Passage: The revisionist paleontologist Robert T. Bakker, who published his findings as The Dinosaur Heresies, treated the mainstream view of dinosaurs as dogma. "I have enormous respect for dinosaur paleontologists past and present. But on average, for the last fifty years, the field hasn't tested dinosaur orthodoxy severely enough." page 27 "Most taxonomists, however, have viewed such new terminology as dangerously destabilizing to the traditional and well-known scheme..." page 462. This book apparently influenced Jurassic Park. The illustrations by the author show dinosaurs in very active poses, in contrast to the traditional perception of lethargy. He is an example of a recent scientific endoheretic.

Output: Who is a modern example of an exoheretic?

Input: Consider Input: Passage: Even though some proofs of complexity-theoretic theorems regularly assume some concrete choice of input encoding, one tries to keep the discussion abstract enough to be independent of the choice of encoding. This can be achieved by ensuring that different representations can be transformed into each other efficiently.

Output: What can not be achieved by ensuring different representations can transformed into each other efficiently?

Input: Consider Input: Passage: The port of Palermo, founded by the Phoenicians over 2,700 years ago, is, together with the port of Messina, the main port of Sicily. From here ferries link Palermo to Cagliari, Genoa, Livorno, Naples, Tunis and other cities and carry a total of almost 2 million passengers annually. It is also an important port for cruise ships. Traffic includes also almost 5 million tonnes of cargo and 80.000 TEU yearly. The port also has links to minor sicilian islands such as Ustica and the Aeolian Islands (via Cefalu in summer). Inside the Port of Palermo there is a section known as "tourist marina" for sailing yachts and catamarans.
Output: What is the main port of Italy?
