You will be given a passage, and your task is to generate a Yes/No question that is answerable based on the given passage.

Input: Consider Input: In mathematics, and more specifically set theory, the empty set or null set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set; in other theories, its existence can be deduced. Many possible properties of sets are vacuously true for the empty set.

Output: is an empty set an element of an empty set?


Input: Consider Input: In their opening match of the 2018 FIFA World Cup, Mexico defeated defending champion Germany, 1--0, for the first time in a World Cup match. They would go on to defeat South Korea 2--1 in the next game, with goals from Carlos Vela and Javier Hernández, but would fall 3--0 to Sweden in the last group stage match. Despite the loss, Mexico qualified to the round of 16 for the seventh-consecutive tournament. In the round of 16, Mexico was defeated 0--2 by Brazil; the defeat meant that for the seventh tournament in a row, Mexico failed to reach the quarterfinals since they last hosted the World Cup in 1986.

Output: has mexico ever beat germany in the world cup?


Input: Consider Input: Linseed oil, also known as flaxseed oil or flax oil, is a colourless to yellowish oil obtained from the dried, ripened seeds of the flax plant (Linum usitatissimum). The oil is obtained by pressing, sometimes followed by solvent extraction. Linseed oil is a drying oil, meaning it can polymerize into a solid form. Due to its polymer-forming properties, linseed oil can be used on its own or blended with combinations of other oils, resins or solvents as an impregnator, drying oil finish or varnish in wood finishing, as a pigment binder in oil paints, as a plasticizer and hardener in putty, and in the manufacture of linoleum. Linseed oil use has declined over the past several decades with increased availability of synthetic alkyd resins--which function similarly but resist yellowing.


Output: is flax oil the same as linseed oil?
