This task is about reading the given passage and construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) its answer is a continuous text span from the paragraph. Avoid creating questions that (i) can be answered correctly without actually understanding the paragraph and (ii) uses same words or phrases given in the passage.

Input: Consider Input: There are several reasons an otherwise valid and agreed upon treaty may be rejected as a binding international agreement, most of which involve problems created at the formation of the treaty.[citation needed] For example, the serial Japan-Korea treaties of 1905, 1907 and 1910 were protested; and they were confirmed as "already null and void" in the 1965 Treaty on Basic Relations between Japan and the Republic of Korea.

Output: When are most of the problems created that might result in an otherwise valid treaty being rejected as a binding international agreement?

Input: Consider Input: Institute of technology (also: university of technology, polytechnic university, technikon, and technical college) is a designation employed for a wide range of learning institutions awarding different types of degrees and operating often at variable levels of the educational system. It may be an institution of higher education and advanced engineering and scientific research or professional vocational education, specializing in science, engineering, and technology or different sorts of technical subjects. It may also refer to a secondary education school focused in vocational training.[citation needed] The term institute of technology is often abbreviated IT and is not to be confused with information technology.

Output: What's a common abbreviation for the term institute of technology?

Input: Consider Input: The Triassic was generally dry, a trend that began in the late Carboniferous, and highly seasonal, especially in the interior of Pangaea. Low sea levels may have also exacerbated temperature extremes. With its high specific heat capacity, water acts as a temperature-stabilizing heat reservoir, and land areas near large bodies of waterespecially the oceansexperience less variation in temperature. Because much of the land that constituted Pangaea was distant from the oceans, temperatures fluctuated greatly, and the interior of Pangaea probably included expansive areas of desert. Abundant red beds and evaporites such as halite support these conclusions, but evidence exists that the generally dry climate of the Triassic was punctuated by episodes of increased rainfall. Most important humid episodes were the Carnian Pluvial Event and one in the Rhaetian, few million years before the TriassicJurassic extinction event.
Output: What was the general rainfall in the Triassic?
