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.

Ex Input:

Ex Output:

Ex Input:
Passage: Worldwide use of solar power and wind power continued to grow significantly in 2012. Solar electricity consumption increased by 58 percent, to 93 terawatt-hours (TWh). Use of wind power in 2012 increased by 18.1 percent, to 521.3 TWh. Global solar and wind energy installed capacities continued to expand even though new investments in these technologies declined during 2012. Worldwide investment in solar power in 2012 was $140.4 billion, an 11 percent decline from 2011, and wind power investment was down 10.1 percent, to $80.3 billion. But due to lower production costs for both technologies, total installed capacities grew sharply. This investment decline, but growth in installed capacity, may again occur in 2013. Analysts expect the market to triple by 2030. In 2015, investment in renewables exceeded fossils.

Ex Output:
In 2012, solar electricity consumption decreased by what percentage?


Ex Input:
Passage: Another term for Christians which appears in the New Testament is "Nazarenes" which is used by the Jewish lawyer Tertullus in Acts 24. Tertullian (Against Marcion 4:8) records that "the Jews call us Nazarenes," while around 331 AD Eusebius records that Christ was called a Nazoraean from the name Nazareth, and that in earlier centuries "Christians," were once called "Nazarenes." The Hebrew equivalent of "Nazarenes", Notzrim, occurs in the Babylonian Talmud, and is still the modern Israeli Hebrew term for Christian.

Ex Output:

What is another term for Christians which appears in the Old Testament?
