In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.

Input: Consider Input: passage: Some non-benzene-based compounds called heteroarenes, which follow Hückel's rule (for monocyclic rings: when the number of its π electrons equals 4n + 2, where n = 0, 1, 2, 3, ...), are also called aromatic compounds. In these compounds, at least one carbon atom is replaced by one of the heteroatoms oxygen, nitrogen, or sulfur. Examples of non-benzene compounds with aromatic properties are furan, a heterocyclic compound with a five-membered ring that includes a single oxygen atom, and pyridine, a heterocyclic compound with a six-membered ring containing one nitrogen atom.
 question: do all aromatic compounds have a benzene ring?

Output: No


Input: Consider Input: passage: Aviation research during World War II led to the creation of the first rocket- and jet-powered aircraft. Several claims of breaking the sound barrier during the war subsequently emerged. However, the first recognized flight exceeding the speed of sound by a manned aircraft in controlled level flight was performed on October 14, 1947 by the experimental Bell X-1 research rocket plane piloted by Charles ``Chuck'' Yeager. The first production plane to break the sound barrier was an F-86 Canadair Sabre with the first 'supersonic' woman pilot, Jacqueline Cochran, at the controls. According to David Masters, the DFS 346 prototype captured in Germany by the Soviets, after being released from a B-29 at 32800 ft (10000 m), reached 683 mph (1100 km/h) late in 1945, which would have exceeded Mach 1 at that height. The pilot in these flights was the German Wolfgang Ziese.
 question: can planes go faster than the speed of sound?

Output: Yes


Input: Consider Input: passage: Joel got the idea for the song when he had just turned 40. He was in a recording studio and met a friend of Sean Lennon who had just turned 21 who said ``It's a terrible time to be 21!'' Joel replied to him, ``Yeah, I remember when I was 21 -- I thought it was an awful time and we had Vietnam, and y'know, drug problems, and civil rights problems and everything seemed to be awful.'' The friend replied, ``Yeah, yeah, yeah, but it's different for you. You were a kid in the fifties and everybody knows that nothing happened in the fifties''. Joel retorted, ``Wait a minute, didn't you hear of the Korean War or the Suez Canal Crisis?'' Joel later said those headlines formed the basic framework for the song.
 question: is we didn't start the fire about the cold war?


Output: No
