TASK DEFINITION: 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.
PROBLEM: Passage: This may be managed directly on an individual basis, or by the assignment of individuals and privileges to groups, or (in the most elaborate models) through the assignment of individuals and groups to roles which are then granted entitlements. Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called "subschemas". For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data. If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases.

SOLUTION: What does data security support?

PROBLEM: Passage: Dallin H. Oaks replaced Wilkinson as president in 1971. Oaks continued the expansion of his predecessor, adding a law school and proposing plans for a new School of Management. During his administration, a new library was also added, doubling the library space on campus. Jeffrey R. Holland followed as president in 1980, encouraging a combination of educational excellence and religious faith at the university. He believed that one of the school's greatest strengths was its religious nature and that this should be taken advantage of rather than hidden. During his administration, the university added a campus in Jerusalem, now called the BYU Jerusalem Center. In 1989, Holland was replaced by Rex E. Lee. Lee was responsible for the Benson Science Building and the Museum of Art on campus. A cancer victim, Lee is memorialized annually at BYU during a cancer fundraiser called the Rex Lee Run. Shortly before his death, Lee was replaced in 1995 by Merrill J. Bateman.

SOLUTION: Who replaced Wilkinson as president in 1980?

PROBLEM: Passage: Another issue has been the use of a hypopodium as a standing platform to support the feet, given that the hands may not have been able to support the weight. In the 17th century Rasmus Bartholin considered a number of analytical scenarios of that topic. In the 20th century, forensic pathologist Frederick Zugibe performed a number of crucifixion experiments by using ropes to hang human subjects at various angles and hand positions. His experiments support an angled suspension, and a two-beamed cross, and perhaps some form of foot support, given that in an Aufbinden form of suspension from a straight stake (as used by the Nazis in the Dachau concentration camp during World War II), death comes rather quickly.

SOLUTION:
In what century did Rasmos Bartholin perform crucifixion experiments?
