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.

Passage: The effects of local surface low pressure are extremely limited because upper-level subsidence still continues to block any form of air ascent. Also, to be protected against rain-bearing weather systems by the atmospheric circulation itself, the desert is made even drier by his geographical configuration and location. Indeed, the extreme aridity of the Sahara can't be only explained by the subtropical high pressure. The Atlas Mountains, found in Algeria, Morocco and Tunisia also help to enhance the aridity of the northern part of the desert. These major mountain ranges act as a barrier causing a strong rain shadow effect on the leeward side by dropping much of the humidity brought by atmospheric disturbances along the polar front which affects the surrounding Mediterranean climates.
what is blocked buy the surface low pressure?

Passage: Dunn and Dunn focused on identifying relevant stimuli that may influence learning and manipulating the school environment, at about the same time as Joseph Renzulli recommended varying teaching strategies. Howard Gardner identified a wide range of modalities in his Multiple Intelligences theories. The Myers-Briggs Type Indicator and Keirsey Temperament Sorter, based on the works of Jung, focus on understanding how people's personality affects the way they interact personally, and how this affects the way individuals respond to each other within the learning environment. The work of David Kolb and Anthony Gregorc's Type Delineator follows a similar but more simplified approach.
Who discredited identifying stimuli that can influence learning?

Passage: The 2004 election was the first to be affected by the campaign finance reforms mandated by the Bipartisan Campaign Reform Act of 2002 (also known as the McCainFeingold Bill for its sponsors in the United States Senate). Because of the Act's restrictions on candidates' and parties' fundraising, a large number of so-called 527 groups emerged. Named for a section of the Internal Revenue Code, these groups were able to raise large amounts of money for various political causes as long as they do not coordinate their activities with political campaigns. Examples of 527s include Swift Boat Veterans for Truth, MoveOn.org, the Media Fund, and America Coming Together. Many such groups were active throughout the campaign season. (There was some similar activity, although on a much lesser scale, during the 2000 campaign.)
