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: Regardless of the way the tension between universities, individual scientists, and the scientific revolution itself is perceived, there was a discernible impact on the way that university education was constructed. Aristotelian epistemology provided a coherent framework not simply for knowledge and knowledge construction, but also for the training of scholars within the higher education setting. The creation of new scientific constructs during the scientific revolution, and the epistemological challenges that were inherent within this creation, initiated the idea of both the autonomy of science and the hierarchy of the disciplines. Instead of entering higher education to become a "general scholar" immersed in becoming proficient in the entire curriculum, there emerged a type of scholar that put science first and viewed it as a vocation in itself. The divergence between those focused on science and those still entrenched in the idea of a general scholar exacerbated the epistemological tensions that were already beginning to emerge.

SOLUTION: What type of epistemology served as the foundation of knowledge constructions and training students in universities?

PROBLEM: Passage: Conventional ("tailhook") aircraft rely upon a landing signal officer (LSO, radio call sign paddles) to monitor the aircraft's approach, visually gauge glideslope, attitude, and airspeed, and transmit that data to the pilot. Before the angled deck emerged in the 1950s, LSOs used colored paddles to signal corrections to the pilot (hence the nickname). From the late 1950s onward, visual landing aids such as Optical Landing System have provided information on proper glide slope, but LSOs still transmit voice calls to approaching pilots by radio.

SOLUTION: What does OSL stand for?

PROBLEM: Passage: Additionally, owing to its colonial history, cuisine in Eritrea features more Italian influences than are present in Ethiopian cooking, including more pasta and greater use of curry powders and cumin.The Italian Eritrean cuisine started to be practiced during the colonial times of the Kingdom of Italy, when a large number of Italians moved to Eritrea. They brought the use of "pasta" to Italian Eritrea, and it is one of the main food eaten in present-day Asmara. An Italian Eritrean cuisine emerged, and dishes common dishes are 'Pasta al Sugo e Berbere', which means "Pasta with tomato sauce and berbere" (spice), but there are many more like "lasagna" and "cotoletta alla milanese" (milano cutlet). Alongside sowa, people in Eritrea also tend to drink coffee. Mies is another popular local alcoholic beverage, made out of honey.

SOLUTION:
What is one of the main foods eaten in Ethiopia?
