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: In Ancient Greece, green and blue were sometimes considered the same color, and the same word sometimes described the color of the sea and the color of trees. The philosopher Democritus described two different greens; cloron, or pale green, and prasinon, or leek green. Aristotle considered that green was located midway between black, symbolizing the earth, and white, symbolizing water. However, green was not counted among of the four classic colors of Greek painting; red, yellow, black and white, and is rarely found in Greek art.
answer:
How many blues did Democritus describe?


question:
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.
answer:
 Who discredited identifying stimuli that can influence learning?


question:
Passage: The two major types of nonprofit organization are membership and board-only. A membership organization elects the board and has regular meetings and the power to amend the bylaws. A board-only organization typically has a self-selected board, and a membership whose powers are limited to those delegated to it by the board. A board-only organization's bylaws may even state that the organization does not have any membership, although the organization's literature may refer to its donors or service recipients as "members"; examples of such organizations are Fairvote and the National Organization for the Reform of Marijuana Laws. The Model Nonprofit Corporation Act imposes many complexities and requirements on membership decision-making. Accordingly, many organizations, such as Wikimedia, have formed board-only structures. The National Association of Parliamentarians has generated concerns about the implications of this trend for the future of openness, accountability, and understanding of public concerns in nonprofit organizations. Specifically, they note that nonprofit organizations, unlike business corporations, are not subject to market discipline for products and shareholder discipline of their capital; therefore, without membership control of major decisions such as election of the board, there are few inherent safeguards against abuse. A rebuttal to this might be that as nonprofit organizations grow and seek larger donations, the degree of scrutiny increases, including expectations of audited financial statements. A further rebuttal might be that NPOs are constrained, by their choice of legal structure, from financial benefit as far as distribution of profit to its members/directors is concerned. Beware of board-only organizations- review the board members annual income before donating, such as the Clinton Foundation. Board members who decide what percentage of your donations will increase their personal wealth are rampant in abusing this designation of an NPO, and this is why they attempt to avoid audits and use a double bottom line for taxing.
answer:

What are two examples of a membership organization?
