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.
Q: Passage: The lower (Triassic) boundary is set by the PermianTriassic extinction event, during which approximately 90% to 96% of marine species and 70% of terrestrial vertebrates became extinct. It is also known as the "Great Dying" because it is considered the largest mass extinction in the Earth's history. The upper (Cretaceous) boundary is set at the CretaceousTertiary (KT) extinction event (now more accurately called the CretaceousPaleogene (or KPg) extinction event), which may have been caused by the impactor that created Chicxulub Crater on the Yucatan Peninsula. Towards the Late Cretaceous large volcanic eruptions are also believed to have contributed to the CretaceousPaleogene extinction event. Approximately 50% of all genera became extinct, including all of the non-avian dinosaurs.
A:
What percentage of marine life growth happened during the PermianTriassic era?
